Office Fit-Out: Definition, Stages, Timeline and Renovation Costs in 2026

Office fit-out is the comprehensive process of preparing a space for operation—from space planning and engineering design to finishes, furniture installation, multimedia systems and commissioning every work area. The owner or tenant receives more than a renovated space: they get a fully operational office ready for employees to move in.

In 2026, indicative office fit-out costs in Moscow start at approximately RUB 100,000–120,000 per square metre for a standard project. A business-grade office may require RUB 150,000–180,000 per square metre, while a premium headquarters with complex engineering and bespoke solutions may cost RUB 240,000–300,000 per square metre or more.

These figures should not be treated as a fixed price list. The final cost depends on the initial condition and size of the premises, the standard of finishes, engineering systems, furniture, schedule and the building management requirements.

The costliest mistake is not choosing high-quality materials, but starting construction without a precise technical brief. Changes are then made during the build, completed work must be redone, and the move-in date keeps slipping.

Below we explain what fit-out includes, how it differs from conventional refurbishment, how long a project takes and how to estimate the budget in advance.

What Does Office Fit-Out Mean?

Fit-out is the range of works that turns an empty or partially prepared space into a fully functioning office.

A fit-out may include:

• site assessment;
• concept development;
• space planning;
• interior design;
• engineering design;
• construction and finishing works;
• ventilation and air conditioning;
• power supply;
• lighting;
• low-voltage systems;
• access control;
• fire safety systems;
• multimedia equipment;
• acoustic treatment;
• furniture;
• wayfinding;
• decorative finishes;
• move-in preparation.

The scope of service may vary from one contractor to another.

One company may use the term fit-out only for design and construction work. Another may also include furniture, connectivity, meeting-room equipment and move management.

When comparing bids, therefore, focus not on the headline cost per square metre but on the detailed scope included in each estimate.

How Fit-Out Differs from Conventional Refurbishment

Conventional refurbishment most often focuses on finishes:

• levelling surfaces;
• painting walls;
• laying floor finishes;
• installing doors;
• replacing the ceiling;
• upgrading lighting.

Fit-out treats the office as one integrated working system.

A visually attractive finish is not enough. The project must establish:

• how many people will work in the office;
• where meetings will take place;
• how much electrical capacity is required;
• how the ventilation operates;
• how workstations will be connected;
• where the server room will be located;
• how visitors move from reception to a meeting room;
• whether the sales team will disturb the analysts;
• whether the office can be adapted in several years.

Refurbishment is therefore one component of a fit-out, but it does not replace the complete process.

Shell & Core, White Box and Fully Fitted Offices

Fit-out cost and duration largely depend on the condition in which the space is handed over.

Shell & Core

Shell & core is often described as a bare concrete space.

It may include:

• structural elements;
• the façade and windows;
• utility connection points;
• base-building systems;
• a screed or unfinished floor;
• unfinished walls and ceilings.

Internal partitions, full lighting, floor finishes and internal engineering distribution are generally absent.

The principal advantage of shell & core is complete design freedom. A company can create an office from scratch around its own operating processes.

Disadvantages:

• the highest budget requirement;
• a longer programme;
• the need for a complete design package;
• greater exposure to design changes;
• a large number of approvals.

This format suits a company that expects to occupy the office for a long time and wants a bespoke headquarters.

White Box

White box is a space with basic preparation completed before final finishes.

Depending on the building, the following may already be provided:

• floor screed;
• levelled walls;
• partial engineering distribution;
• basic lighting;
• ceiling preparation;
• toilets;
• utility connection points.

The principal advantage is a reduction in the amount of preliminary construction work.

However, the term white box does not have an identical meaning across all developments. Before committing, obtain a detailed schedule showing what has already been completed, which materials were used and what may need to be redone.

Sometimes the completed base finish does not suit the future layout. In that case, some of the work already paid for by the buyer must be removed.

Fully Fitted Office

A completed space can enable a faster move, but it may not suit the new owner.

Check the following:

• whether the layout is suitable;
• the condition of the engineering systems;
• the number of workstations;
• the quality of finishing materials;
• acoustics;
• available electrical capacity;
• the server room;
• ventilation;
• furniture wear;
• the scope for alterations.

An attractive interior can conceal engineering limitations. A technical audit is therefore essential before purchasing a completed office.

A detailed property-assessment procedure is provided in the article “How to Choose an Office in Moscow City”.

Main Types of Fit-Out

Standard Fit-Out

Suitable for functional offices without complex architectural features.

Typically includes:

• a functional space plan;
• standard partitions;
• basic lighting;
• commercial-grade flooring;
• standard ceiling solutions;
• essential engineering systems;
• standard meeting rooms;
• off-the-shelf furniture.

The main objective is to create a reliable office within a controlled budget.

Business-Grade Fit-Out

This format places higher demands on design, acoustics and engineering systems.

The project may include:

• glass partitions;
• tailored lighting scenes;
• high-quality furniture;
• an advanced air-conditioning system;
• phone booths;
• multimedia-enabled meeting rooms;
• acoustic panels;
• desk-booking systems;
• automated access control.

This format is often chosen by companies that need the office to be comfortable for the team while also presenting well in client meetings.

Premium Fit-Out

A premium project is developed individually and rarely fits a standard set of solutions.

It may feature:

• natural stone;
• fine woods;
• bespoke furniture;
• feature lighting;
• complex ceiling structures;
• bespoke engineering solutions;
• professional AV systems;
• reconfigurable spaces;
• artworks;
• automated climate and lighting control;
• enhanced security.

In a premium headquarters, a coherent architectural concept matters more than the materials in isolation.

Expensive marble will not fix an inconvenient layout, and designer furniture will not compensate for noisy ventilation.

How Much Does Office Fit-Out Cost in 2026?

The following benchmarks can be used for preliminary budgeting:

Project standard	Indicative cost per m²	Typical inclusions
Basic standard	RUB 100,000–120,000	Basic finishes, base engineering systems and standard solutions
Business grade	RUB 150,000–180,000	High-quality materials, a complete engineering fit-out, acoustic treatment and meeting rooms
Premium	RUB 240,000–300,000 and above	Bespoke design, complex engineering systems and custom solutions

Prices are indicative and include VAT. The actual estimate may differ materially.

The cost per square metre may exclude:

• furniture;
• IT equipment;
• servers;
• computers;
• video walls;
• professional conferencing systems;
• artworks;
• move services;
• removal of existing finishes;
• building management charges;
• work outside standard hours.

Before comparing two proposals, therefore, make sure they cover the same scope.

Example Budget Calculation

Consider a hypothetical office measuring 1,000 m².

Standard Project

With a budget of RUB 110,000 per square metre:

1,000 × 110,000 = RUB 110,000,000.

Business grade

With a budget of RUB 165,000 per square metre:

1,000 × 165,000 = RUB 165,000,000.

Premium Project

With a budget of RUB 270,000 per square metre:

1,000 × 270,000 = RUB 270,000,000.

The following costs may need to be added:

• furniture;
• employee equipment;
• a contingency for changes;
• relocation;
• temporary office costs;
• additional building management requirements.

For a complex project, it is advisable to allow a contingency of at least 10–15% of the approved budget.

This does not mean the contingency will necessarily be spent. It protects the project from stalling if concealed works are discovered or requirements change.

What Determines Fit-Out Cost

Initial Condition of the Space

A fit-out from shell & core is almost always more expensive than adapting a good-quality white box.

However, a poorly executed white box can increase costs if completed elements have to be removed.

Office Size

Larger spaces can have a lower cost per square metre because some expenses are spread over a greater area.

However, a large-scale office requires:

• more engineering systems;
• more complex project management;
• multiple work phases;
• more approvals;
• substantial materials logistics.

Layout

An open-plan layout is generally less expensive than a cellular office because it requires fewer doors, partitions and separately serviced zones.

However, an open-plan office needs acoustic treatment, phone booths and additional meeting rooms.

Before starting the design, it is useful to review types of office layouts and choose a format that reflects the company’s actual working processes.

Engineering Systems

Engineering systems can account for a substantial share of the budget.

Particularly costly elements include:

• ventilation;
• air conditioning;
• power supply;
• controls and automation;
• fire protection systems;
• low-voltage networks;
• the server room;
• access control;
• multimedia systems.

Cutting costs on engineering systems rarely goes unnoticed. Once the office is occupied, the company may face poor air quality, overheating meeting rooms, noisy equipment and insufficient electrical capacity.

Material Standard

The price depends not only on appearance, but also on:

• wear resistance;
• fire performance;
• acoustic properties;
• maintainability;
• availability of replacements;
• lead times.

An exclusive material that cannot be reordered quickly may complicate local repairs several years later.

Work Programme

An accelerated fit-out almost always costs more.

The contractor may need to:

• increase the workforce;
• organise multiple shifts;
• carry out work at night;
• expedite deliveries;
• run otherwise incompatible activities in parallel.

Before signing the contract, make sure the proposed programme is physically achievable.

How Long Does an Office Fit-Out Take?

Indicative project durations:

Area	Indicative total duration
Up to 300 m²	2–3 months
300–1,000 m²	3–5 months
1,000–3,000 m²	5–8 months
3,000–5,000+ m²	8–12 months or more

The total programme includes more than construction work. It also covers:

• survey;
• concept development;
• design;
• approvals;
• procurement;
• construction;
• testing and commissioning;
• snagging;
• furnishing;
• move-in preparation.

If only the visible finishes are counted, the programme will appear shorter. The company cannot move in, however, until ventilation, connectivity, security systems and workstations are operational.

Fit-Out Project Stages

1. Define Business Requirements

The project does not begin with choosing a wall colour.

Establish the following:

• headcount;
• a hybrid or full-time working pattern;
• the number of workstations;
• department types;
• visitor numbers;
• meeting rooms;
• private offices;
• the need for a conference room;
• security requirements;
• the company’s growth forecast.

For a preliminary calculation, use the guide on how much office space is required per employee.

2. Conduct a Technical Audit of the Space

Specialists inspect:

• the condition of structural elements;
• available electrical capacity;
• connection points;
• ventilation;
• cooling supply;
• water supply;
• fire protection systems;
• floor-slab limitations;
• the operation of base-building equipment;
• building management requirements.

The audit should ideally be completed before purchasing the space or signing a long-term lease.

If the space cannot provide the required electrical capacity or air exchange, even an attractive design will be impractical.

3. Prepare a Test-Fit Layout

The plan should show:

• workstations;
• private offices;
• meeting rooms;
• a kitchen;
• reception;
• a cloakroom;
• the server room;
• breakout areas;
• circulation routes;
• technical rooms.

A test-fit layout shows whether the selected floor area genuinely meets the company’s needs.

This stage often reveals that an apparently large office loses a substantial amount of usable area to columns, the lift core and complex geometry.

4. Develop the Concept

The concept defines the overall character of the space:

• formal or informal;
• high-tech or intimate;
• open or private;
• neutral or branded;
• designed for full-time or hybrid work.

A strong concept connects the interior with business objectives. It should not become a collection of fashionable images that cannot be delivered within the available budget.

5. Develop the Design

Architectural and engineering design packages are developed.

The design package usually includes:

• architectural solutions;
• partitions;
• ceilings;
• floors;
• a furniture layout;
• power supply;
• lighting;
• ventilation and air conditioning;
• water supply;
• fire safety systems;
• low-voltage networks;
• access control;
• multimedia systems;
• acoustic design.

The more detailed the design, the more accurate the estimate and the lower the risk of disputes during construction.

6. Obtain Building Management Approval

The business centre may impose requirements concerning:

• contractors;
• fire safety;
• material deliveries;
• permitted hours for noisy work;
• waste removal;
• lift use;
• engineering connections;
• the renovation programme;
• insurance;
• worker access passes.

Approvals in a high-rise are usually more complex than in a small standalone office building.

7. Prepare the Estimate and Programme

The estimate must be tied to the design documentation.

It is risky to accept a proposal consisting of a single line:

Fit-out — RUB 150,000 per square metre.

The proposal should show:

• quantities;
• materials;
• equipment;
• work items;
• the programme;
• liability;
• exclusions;
• the change-control procedure.

A separate procurement schedule should be agreed. Some materials and engineering equipment must be ordered well in advance.

8. Carry Out the Construction Works

The following works are carried out on site:

• demolition;
• partitions;
• engineering distribution;
• ceilings;
• floors;
• finishes;
• doors;
• lighting;
• equipment installation;
• installation of interior elements.

Completed work should be checked against the design regularly rather than only at final handover.

9. Test and Commission the Systems

Engineering systems are tested under operating conditions.

Tests cover:

• ventilation;
• temperature;
• lighting;
• fire alarm and control systems;
• power supply;
• backup power;
• internet connectivity;
• access control;
• CCTV;
• meeting-room systems.

An empty meeting room may feel comfortable, but temperature and noise levels change when it is occupied. Some tests should therefore be carried out under the design occupancy load.

10. Furnish the Office and Prepare for the Move

Once the main works are complete, the following are installed:

• desks;
• chairs;
• cabinets;
• soft seating;
• kitchen units;
• storage systems;
• meeting-room equipment;
• wayfinding;
• decorative elements.

Before the move, check every workstation:

• whether the power socket works;
• whether internet access is available;
• whether the lighting is configured correctly;
• whether cabinets open properly;
• whether chairs obstruct circulation;
• whether sufficient fresh air is supplied.

How to Choose a Fit-Out Contractor

The contractor must be able not only to deliver finishing works, but also to manage a complex project.

Request the following:

• a portfolio of comparable projects;
• experience in the relevant business centre;
• the proposed team structure;
• evidence of financial stability;
• insurance cover;
• client references;
• a sample estimate;
• a sample programme;
• the quality-control procedure;
• warranty obligations.

Attractive photographs do not show how well the contractor maintained the programme and budget.

Speak to previous clients and ask:

• how many changes were made;
• how mistakes were resolved;
• whether the final cost changed;
• whether there were delays;
• how the contractor performed after handover.

General Contractor or Multiple Contractors

One General Contractor

Advantages:

• single-point responsibility;
• easier programme management;
• fewer conflicts between contractors;
• one contract;
• a clear point of communication.

The disadvantage is greater dependence on a single contractor.

Multiple Contractors

The company can appoint separate:

• building contractors;
• engineering contractors;
• furniture suppliers;
• an IT contractor;
• an AV supplier.

This approach provides greater control over pricing but requires a strong project-management team.

If no one is responsible for overall coordination, contractors begin shifting responsibility to one another.

How to Stay Within Budget

Freeze the Technical Brief

Every late change increases cost.

Changes become particularly expensive after:

• partition installation;
• cable installation;
• furniture orders have been placed;
• ceiling installation;
• engineering systems have been connected.

Conduct the Audit Early

Concealed problems are best identified before construction begins.

Approve Materials and Alternatives

For key items, agree acceptable substitutes in advance.

Separate Essential and Desirable Items

The estimate can be divided into three levels:

1. Items without which the office cannot operate.
2. Items that materially improve comfort.
3. Decorative or brand-enhancing items.

If savings are required, begin with the third level rather than ventilation or fire safety.

Control Changes

Every change request should include:

• a description;
• the reason;
• the cost;
• the effect on the programme;
• the person responsible for approval.

Verbal agreements on site almost always lead to disputes.

Fit-Out and Operating Costs

A well-designed fit-out can reduce future costs if it includes:

• energy-efficient lighting;
• zoned climate control;
• automatic equipment shut-off;
• maintainable materials;
• access to engineering systems;
• standard replaceable components.

A complex interior can also increase maintenance costs.

For example:

• bespoke lighting requires expensive components;
• natural stone requires specialist care;
• bespoke furniture can be difficult to repair;
• extensive automation requires ongoing maintenance;
• rare materials have long lead times.

The CAPEX required to create an office should therefore be considered alongside future OPEX. Recurring costs are examined in detail in the article on office operating costs.

Class A Office Fit-Out

Fit-out requirements are generally more demanding in a Class A business centre.

The reasons include:

• complex centralised building systems;
• strict building management requirements;
• premium common areas;
• rules governing façade works;
• fire-safety controls;
• noise restrictions;
• complex logistics;
• the use of service lifts.

Unauthorised changes to engineering systems can affect not only the office but the operation of the entire floor.

Therefore, when selecting a Class A office in Moscow City obtain the tenant or owner technical guide in advance.

Special Considerations for Fit-Out in a Skyscraper

A high-rise office creates additional challenges:

• material deliveries;
• restricted operation of freight lifts;
• wind loads on the façade;
• panoramic glazing;
• solar shading;
• complex cooling requirements;
• enhanced fire-safety requirements;
• long evacuation routes;
• equipment weight limits;
• access-control procedures.

The climate-control design requires particular attention.

A space with panoramic glazing can experience significant solar heat gain, while a 15-person meeting room requires a dedicated air-exchange calculation.

F-375 as an Example of an Integrated Fit-Out

The F-375 office penthouse occupies 2,642 m² across the three upper levels of Federation Tower East.

The space supports a range of working scenarios:

• open-plan workspace;
• team offices;
• meeting rooms;
• quiet rooms;
• a library;
• a dining area;
• executive offices;
• VIP meeting rooms;
• a principal executive level;
• a conference hall;
• reception and hospitality areas.

The three levels are connected by a unified architectural and engineering concept. The upper section sits beneath a glass dome approximately 14 metres high.

A project of this scale cannot be assessed solely by an average cost per square metre. The budget is influenced by:

• complex architecture;
• height;
• AV systems;
• climate control;
• security;
• automation;
• bespoke furniture;
• multi-level wayfinding;
• privacy requirements.

F-375 demonstrates that premium fit-out is not simply expensive finishing for visual impact. It creates an environment in which workplace, management and representative functions form one integrated system.

Detailed specifications are available on the page for the office in Federation Tower.

Fit-Out for Purchased and Leased Offices

Purchasing an office gives the company greater freedom:

• it can invest in bespoke solutions;
• there is no lease expiry to consider;
• long-term returns are easier to plan;
• capital improvements can increase the value of the asset.

When leasing, check:

• the lease term;
• the rent-free period;
• any fit-out contribution;
• any obligation to reinstate the premises;
• the right to remove equipment;
• the fit-out approval procedure;
• the treatment of permanent tenant improvements.

Before making a significant investment, review the complete process for buying an office in Moscow City.

Common Fit-Out Mistakes

Starting Construction Without a Working Design

Decisions are made directly on site and change continuously.

Selecting a Contractor on Price Alone

Important work items may be absent from the estimate and appear later.

Cutting Costs on the Technical Audit

Problems are discovered only after demolition or partition installation.

Ignoring Business Centre Requirements

The design must be revised after it is submitted for approval.

Ordering Furniture Too Late

The fit-out is complete, but the company cannot move in for several months.

Designing the Office Without Employee Input

Management receives an attractive space that is inconvenient for the team’s daily work.

Failing to Plan for Growth

A year later, meeting rooms become private offices and breakout areas become workstations.

Budgeting Only for Construction Work

The budget omits furniture, equipment, connectivity, relocation and contingency.

Failing to Test the Office Under Load

Overheating, noise and insufficient fresh air become apparent only after occupation.

How to Organise an Office Fit-Out: Step by Step

Step 1. Define the Business Objectives

Define the team size, working model and functions of the future office.

Step 2. Conduct a Technical Audit

Check the engineering systems, available capacity, restrictions and condition of the space.

Step 3. Prepare a Test-Fit Layout

Make sure the office genuinely accommodates all required areas.

Step 4. Select the Project Standard

Choose a standard, business-grade or premium format.

Step 5. Develop the Design

Prepare the architectural and engineering design packages.

Step 6. Obtain the Required Approvals

Obtain approval from building management and the relevant specialists.

Step 7. Prepare a Detailed Estimate

Compare contractors using the same scope of work.

Step 8. Prepare a Realistic Programme

Allow for design, procurement, construction, furniture and relocation.

Step 9. Monitor the Works

Regularly check quality, budget and compliance with the design.

Step 10. Test and Commission

Test all systems before employees move in.

In Brief: What You Need to Know About Fit-Out

Fit-out is the comprehensive creation of a fully operational office, not merely the finishing of walls and floors.

In 2026, indicative budgets are:

• RUB 100,000–120,000 per m² for a standard office;
• RUB 150,000–180,000 per m² for a business-grade project;
• RUB 240,000–300,000 per m² or more for a premium fit-out.

The total programme typically ranges from two to three months for a small space to eight to twelve months for a large headquarters.

An accurate budget can only be established after a technical audit, space planning and completion of the working design.

The key rule is to design workplace processes and engineering systems first, and only then select materials, furniture and decorative solutions.

Frequently Asked Questions

What is an office fit-out?

Fit-out is the comprehensive design, construction, engineering installation and furnishing of an office until it is fully ready for operation.

How does fit-out differ from refurbishment?

Refurbishment mainly concerns finishes. Fit-out additionally covers space planning, engineering systems, connectivity, security, furniture and workstation preparation.

How much does an office fit-out cost in 2026?

A standard project may cost approximately RUB 100,000–120,000 per m², a business-grade fit-out RUB 150,000–180,000 per m², and a premium project RUB 240,000–300,000 per m² or more.

How long does an office fit-out take?

A small office can be completed in two to three months. A large project covering several thousand square metres may take from eight months to a year.

What is included in the fit-out cost?

Design, engineering systems, construction work, finishing materials and project management. Furniture, IT and AV systems may be priced separately.

Which is better: shell & core or white box?

Shell & core offers maximum freedom but requires more time and budget. White box allows final finishing to begin sooner, provided the completed work suits the future layout.

How much contingency should be included in the budget?

For a complex project, a contingency of approximately 10–15% is reasonable for changes and unforeseen work.

Can fit-out begin before the lease is signed?

Design can begin once the technical information has been received, but committing funds to construction is safer after the lease is signed and rights to the improvements are documented.
