Design & Build Services in London for Complete Interior Transformations
Oraanj provides Design & Build services for residential and commercial properties
across London. We bring interior design, technical planning, procurement, renovation and project management
together, giving you one coordinated team from the first design ideas through to the finished interior.
Whether you are renovating a house, transforming an apartment or creating a new
commercial interior, we plan the project before the main works begin and manage its delivery through to
completion.
You Have the Property. What Happens Next?
A renovation can quickly involve a long list of people.
Without a single team holding the design intent, you become the coordinator between
conflicting parties. That is the fundamental role of an integrated Design & Build service: instead of
treating design, technical information, procurement and physical works as separate projects, we plan how they
connect from the beginning.

And somebody still has to make sure they are all working towards the same design.

One project. One coordinated route from design to delivery.
What Does Design & Build Mean?
At Oraanj, Design & Build doesn’t mean starting construction and making design decisions
as the project progresses.
We develop the interior first. Layouts, lighting, materials, joinery and other important
design decisions are considered before the main renovation begins.
The approved design can then be developed into the information required for implementation.
This creates a clearer basis for costing, procurement and the works on site.
What Can Oraanj Manage?
Our single-contract model brings together all the services needed to take a property from
concept to handover.
Instead of appointing separate consultants and managing fragmented communication between
builders, designers and suppliers, Oraanj provides single-point accountability across seven core project
disciplines.
Design & Build or a Traditional Renovation?
The Difference Is Where the Responsibility Sits
The appropriate route depends on how involved you want to be and whether you already have
your own contractor and project team.
In a traditional renovation, the homeowner or business owner acts as the unpaid coordinator
between separate architects, main contractors, specialist joiners, and multiple suppliers. With Oraanj Design
& Build, complete accountability rests with one unified team.
Residential Design & Build
Renovating Your Home Without Managing the Whole Project Yourself
A complete home renovation can involve hundreds of decisions.
Where should the lighting go? Which walls or layouts are changing? When should the kitchen
be ordered? Who is producing the joinery drawings? When does the flooring arrive? Who checks whether the
furniture dimensions work? Who coordinates the different trades?
Our residential Design & Build service is intended for clients who want the interior
planned properly and the wider project coordinated through implementation.
Buying a Property to Renovate?
Start the Design Before the Building Work
If you have recently purchased a property that needs substantial work, it can be tempting to
ask contractors for quotations immediately.
But a contractor can only price what has been defined. Before the main renovation begins,
essential decisions include:
Developing these decisions earlier gives the wider project a clearer starting
point and protects your budget.
Commercial Design & Build
From Empty Premises to a Working Interior
Commercial projects bring another set of priorities.
The space needs to work around customers, employees, operational flow, storage, durability,
brand identity, strict opening dates, landlord requirements, and specialist equipment.
Oraanj works on selected commercial interiors including offices, restaurants, cafés, and
retail spaces. We can take the interior from space planning and concept through technical development,
refurbishment, fit-out, procurement and installation.
The Decisions We Make Before Work Starts
What Gets Resolved During the Design Stage?
The more important decisions that can be resolved before implementation, the clearer the project becomes.
Space Planning
How should the property function, circulate, and adapt to daily life?
Illumination Scheme
Where should architectural, task, and decorative lighting be positioned?
Small Power & Data
Where are sockets, switches, AV, and equipment controls required?
Kitchens & Bathrooms
How do technical plumbing and specialist cabinetry connect with the wider interior?
Bespoke Cabinetry
What needs to be designed and fabricated specifically for the property?
Finishes & Surfaces
Which stone, timber, tiles, and fabrics are specified, and where do they transition?
Loose FF&E
What dimensions, pieces, and fabrics need to fit harmoniously into the finished rooms?
Lead Times
Which long-lead items must be ordered early to protect the on-site programme?
How Your Design & Build Project Moves Forward?
A clear nine-stage progression from early consultation through to completed handover.
Consultation & Review
Reviewing the property, requirements, programme, and budget.
Space Planning
Exploring layouts and resolving how rooms, furniture and flow connect.
Interior Design
Developing materials, lighting, bespoke joinery, and design direction.
3D Visualisation
Photorealistic 3D visuals to understand and refine the space before build.
Technical Design
Detailed drawings, MEP layouts, and construction specifications.
Costing & Procurement
Transparent pricing on defined design and ordering long-lead items.
Renovation & PM
Works commence on site with coordinated trade supervision and quality control.
Installation
Joinery, lighting, fixtures, and furniture installed to precision.
Handover
Final snagging, testing, cleaning, and review before handing over the finished
interior.
Already Have a Builder?
You Don’t Have to Use Our Full Design & Build Service
If you already have a contractor you trust, you can appoint Oraanj for the interior design
and technical design stages only.
Depending on the project, we can prepare the agreed design drawings, specifications, and
schedules, and your contractor can undertake the physical works.
Alternatively, if you would prefer Oraanj to remain involved during implementation, we can
discuss the appropriate level of project-management support.
London Properties Need More Than a Good CGI
The Property Itself Can Shape the Project
London renovation projects involve practical considerations that aren’t visible in a
finished render.
Apartments
Building-management rules, lift access, parking, delivery hours, and
noisy-working restrictions that influence the site programme.
Leasehold Properties
Certain internal alterations require formal licence to alter approvals,
structural reviews, and landlord or freeholder consents.
Period Properties
Preserving architectural character, uneven historic structures, and building
fabric that affect how new joinery and services integrate.
Listed Properties
Navigating statutory listed building consents, conservation officers, and
heritage restrictions before undertaking physical changes.
What Does a Design & Build Project Cost?
Design Fees and Build Costs Are Different
There isn’t one meaningful fixed price for a Design & Build project without
understanding the premises.
A cosmetic refurbishment has a very different cost from a complete property involving
structural changes, new kitchens, luxury bathrooms, bespoke joinery, and full services overhaul.
The design stage defines what is actually being built. Once the design and scope are
sufficiently developed, the works can be priced on a realistic, transparent basis.
How Long Does Design & Build Take?
Work Backwards From When You Need the Property
The programme depends on the property and scope.
A complete Design & Build project progresses through design, technical development,
approvals, costing, procurement, renovation, bespoke manufacturing, installation, and handover.
Some items—particularly bespoke joinery, specialist furniture, stone, and imported
finishes—have longer lead times and should be considered early. If you have a target completion or move-in
date, tell us at the beginning so the wider programme can be structured around it.
“The design you approve should remain at the centre of the project as it moves
towards the finished interior.”
