Turnkey Interior Design in London for Residential & Commercial Projects
Oraanj provides fully managed turnkey interior design for homes and selected commercial properties across London.
From space planning and interior design to renovation, procurement, bespoke joinery, furniture installation and final styling, we coordinate every stage required to complete the interior.
Our turnkey service is designed for clients who want the finished result without personally managing designers, contractors, suppliers, deliveries and installers. You give us the property. We manage the interior. You receive it finished.
What Does Turnkey Interior Design Actually Mean?
Beyond Drawings. We Take Responsibility for the Finished Property.
Many interior studios stop at mood boards and shopping links, leaving you to manage contractors and delivery chaos. Turnkey means we take total responsibility for bringing the interior to life.
Space Planning & Layout
Determining room circulation, furniture proportions, and sightlines to ensure effortless functionality before any construction starts.
Interior Architecture & CAD
Comprehensive MEP drawings, lighting schedules, small power layouts, and detailed joinery production elevations.
Procurement & Consolidation
Direct trade discounts, international shipping logistics, insured storage holding, and rigorous defect inspection.
Renovation & White Glove
End-to-end site build, custom joinery installation, bespoke furniture placement, and complete styling down to the accessories.
Who Turnkey Interior Design Is For, and What We Manage?
A Complete Service for Clients Who Value Time and Certainty
Turnkey is designed for busy professionals, property investors, overseas buyers, and families who want a beautifully finished home without the burden of running a complex project.
Busy London Owners
Clients who demand uncompromising design quality and luxury standards without sacrificing weekends to manage sub-contractors.
International Buyers
Remote owners who require trusted local management, licence to alter coordination, and complete move-in readiness on landing.
Prime Landlords
Property investors seeking rapid, high-specification interiors that attract premium corporate tenants and maximize yields.
Whole-Home Transformations
Substantial family homes requiring joined-up renovation, bespoke storage joinery, and tailored luxury furnishing throughout.
Turnkey Interior Design for London Homes
From Flats and Townhouses to Substantial Family Residences
A London turnkey project is not one-size-fits-all. A lateral apartment in Marylebone has completely different constraints from a Victorian townhouse in Richmond or a penthouse in Canary Wharf.
Apartments & Penthouses
We navigate complex building management regulations, licences to alter, parking dispensations, acoustic isolation, and freight elevator logistics.
Victorian & Edwardian Townhouses
We balance heritage architectural cornicing and ceiling heights with modern open-plan flow, underfloor heating, and concealed environmental control.
Substantial Family Residences
Whole-home narrative connecting master suites, walk-in dressing rooms, family living zones, utility areas, and intelligent automation seamlessly.
Overseas Owners & New Property Purchases
Complete Local Management While You Are Abroad
Many of our turnkey clients live abroad or have acquired a prime London residence. Oraanj acts as your trusted representative on the ground throughout:
Survey & Key Handover
Direct coordination with estate agents and developers, laser measured surveys, and defect auditing prior to completion.
Virtual Reviews & Samples
Interactive design presentations, curated finish sample boxes couriered internationally, and digital milestone sign-offs.
Licence to Alter Consents
Managing freeholder stipulations, building management approvals, party wall surveyors, and local council compliance.
Weekly Video & Handover
High-definition weekly progress videos, snag testing, utility setup, and handing over the keys to a completely finished home.

A Coordinated Five-Stage Transformation
Every turnkey interior progresses through a structured sequence that protects your programme and budget from start to finish:
The Initial Property
Evaluating proportions, daylight, structural layout, and building services before any works begin.
The Design Concept & 3D CGI
Photorealistic 3D visualisations that resolve spatial flow, colour schemes, and bespoke cabinetry before ordering.
Renovation & Trade Coordination
Strip-out, electrical rewiring, plumbing, plastering, and architectural finishes executed under strict supervision.
Joinery & Furniture Installation
Fitted wardrobes, media walls, custom kitchens, and curated loose furniture delivered and installed seamlessly.
Turnkey Handover
A deep-cleaned, styled, fully operational interior ready for immediate living or tenant occupancy.
Furniture & Spatial Planning Starts With the Floor Plan
Furniture Doesn’t Come at the End — It Drives the Architecture
A common mistake in interior projects is leaving furniture until the renovation is finished. By then, socket positions, pendant drops, wall switches, and radiator locations are already fixed in the wrong places.
Circulation & Scale
Ensuring dining tables, seating groups, and consoles fit comfortably without blocking walkways or natural sightlines.
Electrical Alignment
Floor sockets positioned precisely under sofas; bedside switches and reading sconces wired to exact headboard dimensions.
Architectural Lighting
Ceiling downlights, statement pendants, and joinery LED washes coordinated with key seating zones and artwork locations.
Lead-Time Protection
Bespoke European sofas and Italian cabinetry have 8–14 week lead times; ordering early prevents move-in delays.
Bespoke Joinery Integrated Into Your Home
Fitted Furniture Designed for the Architecture, Not a Showroom
Nothing elevates a London residence like bespoke joinery. Fitted wardrobes, media units, home offices, and concealed storage designed specifically for the dimensions of each room.
Wardrobes & Dressing Rooms
Full-height built-in wardrobes with integrated LED illumination, bronze ironmongery, fluted glass, and velvet-lined jewellery drawers.
Living Room Media Walls
Discreet acoustic panelling, book-matched marble or porcelain hearths, concealed cable management, and display shelving.
Home Offices & Libraries
Integrated desks, bookshelves, concealed printer cabinets, and cable runs designed for focused, ergonomic productivity.
Kitchens & Pantries
Architectural kitchen cabinetry, breakfast cupboards, and concealed utility areas coordinated with high-end appliances.
How a Turnkey Interior Project Moves Forward?
Nine Clear Stages From Initial Property Review to Handover
A turnkey project is not mysterious. It is a carefully managed process where each stage builds logically on the last:
Consultation & Survey
Reviewing property, programme, budget, and taking laser-measured surveys.
Space Planning
Exploring layout options, door positions, and furniture scale.
Concept & Materials
Developing palettes, timber veneers, stone, fabrics, and decorative hardware.
3D Visualisation
Photorealistic renders confirming finishes before procurement starts.
Technical Design
Full MEP, lighting, joinery, and architectural drawings for construction.
Costing & Procurement
Itemised pricing and placing long-lead orders to protect programme.
Renovation & Build
Construction works on site with daily quality control and supervision.
Installation
Bespoke joinery fitted, furniture placed, window dressings hung.
Turnkey Handover
Final snagging, deep cleaning, and handing over the keys to your completed property.
Residential, Commercial & Design & Build Delivery
Flexible Project Appointments Matched to Your Property
Whether your project is a private home, an investment portfolio, or a high-end commercial property, we offer the right level of turnkey integration:
Turnkey vs. Design & Build
Design & Build focuses on architectural drawings and physical renovation. Turnkey encompasses the entire journey: full renovation, plus all curated furniture, custom joinery, bespoke window dressings, decorative lighting, and white-glove styling.
Turnkey Commercial Interiors
We deliver turnkey fit-outs for boutique offices, restaurants, cafés, and retail spaces, managing building regulations, acoustic compliance, commercial joinery, and scheduled trade handovers.
Single Team, Total Accountability
You deal with one studio, one contract, and one dedicated project director from concept to completion—eliminating disputes between designers and independent builders.
What Does Turnkey Interior Design Cost in London?
Transparent Pricing Built on a Defined Scope
Because a turnkey project covers multiple stages — design, construction, bespoke joinery, and furniture — costs vary depending on property size, condition, and specification level.
The investment divides logically into three components:
1. Interior Design & Technical Planning
A transparent fixed design fee based on property footprint and room count, covering space planning, 3D CGI visuals, and complete technical drawing packages.
2. Renovation & Construction
A fully itemised, transparent quotation based on the approved architectural specifications, structural engineering, MEP plans, and material schedules.
3. FF&E, Joinery & Procurement
Trade-discounted pricing for bespoke fitted joinery, designer loose furniture, window treatments, and finishes with full line-item visibility and cost control.
We provide itemised, transparent proposals before works commence so you maintain complete financial control.
