Step 1: Define Your Business Needs and Spatial Requirements
A luxury office fit-out is a capital project that reshapes how a business operates, not simply how its reception looks. According to RICS guidance on commercial property, occupiers increasingly treat workspace as a strategic asset, which is why the planning stage deserves more scrutiny than the finishes. This guide from Wish Interiors walks through the full process, from brief to handover.
Start with the brief. Before any designer puts pen to paper, answer three questions: how many people will occupy the space, how do they actually work, and what must the office achieve over the next five years?
Assessing Occupancy Density and Agile Working Patterns
Occupancy density is the floor area allocated per desk, usually in square metres. Measure genuine peak attendance rather than total headcount, because hybrid patterns mean fewer desks are needed on any given day. A flexible mix of fixed desks, hot-desking zones and enclosed meeting rooms often suits agile working better than a uniform grid of workstations.
Step 2: Set Your Budget and Understand the Cost of a Luxury Office Fit-Out Per Square Foot
The cost of a luxury office fit-out per square foot varies widely with specification, building condition and location, so treat any single figure with caution. What matters is how the budget is structured, not the headline number.
Split capital expenditure into four pots: shell and core works, Category A and Category B fit-out, furniture and equipment, and professional fees. Cat A covers the base building essentials a landlord typically delivers; Cat B covers everything that makes the space yours, from partitions to bespoke joinery.
Where Contingency Budget Should Sit
A contingency budget is the reserve set aside for unforeseen costs. Hold a percentage of total project value untouched, released only when a genuine variation arises. Treat it as insurance, not spare cash for mid-project upgrades.
| Budget Pot | What It Covers | Typical Share |
|---|---|---|
| Shell and core | Base building condition | Fixed by lease |
| Cat A | Landlord's base specification | Fixed by lease |
| Cat B | Partitions, ceilings, finishes | Largest variable |
| Furniture and equipment | Desks, seating, AV | Specification-led |
| Professional fees | Design, project management | Percentage-based |
Step 3: Appoint a Fit-Out Contractor and Commercial Interior Design Team
A fit-out contractor delivers the physical works, while the commercial interior design team translates your brief into drawings and specifications. Some projects use a single turnkey provider for both roles; others split them. For a luxury scheme the appointment matters more than the design, because a weak contractor will erode a good design long before a strong contractor rescues a weak one.
Choose the Right Procurement Route First
The procurement route determines who carries design risk and when you commit to a price. Three routes dominate:
- Traditional (design, bid, build). Appoint the designer first, tender on completed drawings, then appoint the contractor. Highest cost certainty at tender, longest programme, and no contractual link between designer and contractor.
- Design and build. One contractor takes responsibility for both design and construction. Faster, single point of responsibility, but you lose some control over specification unless the employer's requirements are written tightly.
- Two-stage tender. A contractor is appointed early on a pre-construction services agreement to advise on buildability and cost, then prices the works at stage two. This suits complex luxury schemes where early contractor involvement saves more than tendering competition would.
For a bespoke, high-specification scheme, two-stage or design and build with tightly drafted employer's requirements is the common pattern. Traditional suits occupiers who want the design team's independence and accept a longer programme.
What to Interrogate in a Tender Return
Price alone tells you little. Ask every shortlisted contractor for the same pack and compare like for like:
- Comparable projects of similar value, specification and building type, with references you can call.
- A named delivery team, not a bid team. Ask who the project manager and site manager will be, and confirm they will not be moved after award.
- A cost plan broken down by element, not a lump sum, so you can see where money goes and test variations later.
- A programme with float shown, so you can see which activities are genuinely critical.
- Confirmation of who holds responsibility for building regulations approvals, structural calculations and the fire strategy. Ambiguity here starts disputes.
- The defects liability period and snagging process, in writing, before you sign.
Fees, Preliminaries and the Cost of Being Vague
Professional fees for design and project management are typically a percentage of construction value or a fixed lump sum, and the percentage usually falls as project value rises. Contractor preliminaries, site setup, welfare, scaffolding, temporary power, site management, are a separate cost line and can be a meaningful share of the contract sum on a short programme. Vague tender documents mean contractors either price in a risk allowance or qualify their bid, and both cost more than a properly specified tender.
The Human Side of Appointment
This is where most guides stop, and where luxury projects are won or lost. The appointment is also a change event for staff. Bring the design team in early to walk the floor plate with the people who use it, and let the contractor hear directly what the business cannot compromise on. A contractor who has met the occupants builds differently from one working only from drawings, and consulted staff become advocates rather than critics.
Step 4: Master Space Planning and Floor Plate Optimization
Space planning arranges functions, circulation and furniture within the available floor area to support how people work, balancing occupancy density against comfort, privacy and operational efficiency.
Floor plate optimization examines the building's shape and constraints. A deep floor plate may need a central core with perimeter workspaces; a narrow one may suit a spine layout with meeting rooms along one edge.
Acoustic Treatment and Biophilic Design in Layout Decisions
Acoustic treatment belongs in the layout conversation, not the finishing schedule. Meeting pods, soft furnishings and acoustic ceiling rafts reduce noise transfer, and their position affects the plan.

Frequently Asked Questions
How much does it cost to fit out an office?
Costs vary widely depending on specification, building condition and whether you need Cat A or Cat B works. A luxury office fit-out typically sits at the higher end because of bespoke joinery, premium finishes and custom furniture. Build your budget around a cost per square foot figure from your contractor, then add a contingency budget of 10 to 15 percent for unexpected building issues, and account for furniture procurement and MEP services separately.
What are the essential stages of a luxury office fit-out?
The project lifecycle runs through eight stages: defining business needs and spatial requirements, budgeting, appointing a fit-out contractor, space planning, bespoke office furniture design and procurement, meeting commercial office fit-out regulations UK requirements, managing the project timeline through to handover and snagging list, then handling employee change management and technology infrastructure. Skipping any stage usually costs more later, particularly compliance and furniture lead times.
What regulatory standards must a UK office fit-out comply with?
Commercial office fit-out regulations UK requirements cover building regulations approval, fire safety compliance including means of escape and alarm systems, electrical safety, ventilation and HVAC integration, and accessibility provisions. If you are a tenant, your lease agreement will also set out dilapidations obligations and any landlord approval needed before works start. Appoint a contractor who handles building control submissions as part of a turnkey solution so nothing is missed.
How can bespoke furniture elevate an office interior?
Bespoke office furniture design solves problems standard pieces cannot, such as awkward floor plates, low ceilings or unusual room shapes. Made-to-measure desks, storage and upholstery create a coherent look rather than a showroom of mismatched items, and they hold up better under daily commercial use. Pieces like the Bradbury Home Office Desk at £129.99 or the Heritage Ivory Desk with Drawer and Shelves at £214.95 show how considered design lifts a workspace without a huge spend.
