Construction Services in London for Complete Interior Transformations
Oraanj delivers interior construction, refurbishment and fit-out projects for residential and commercial properties across London.
Our focus is on transforming existing interiors — from complete house and apartment refurbishments to offices, restaurants, cafés and other commercial fit-outs.
If your design is already developed, we can review the drawings, specifications and proposed scope and discuss the next stage of construction.
If you still need the interior designed, Oraanj can also provide a complete Design & Build service from initial concept through to completion.
From Approved Design to Completion
Send Us the Project Information
If you already have an interior designer, architect or completed design package, you may not need another design service.
You need somebody to understand what has been designed and determine what is required to build it.

Find the Gaps Before Work Begins
A CGI can show what the finished room should look like. It doesn’t necessarily explain how everything should be built.
Before meaningful costing and construction, we identify what must be resolved to protect your programme and budget.
Demolition & retention scope
Clear, site-checked dimensions
Lighting positions & circuits
Sockets, switches & AV points
Finalised kitchen cabinetry
Bathroom valves & waste runs
Bespoke joinery elevations
Specialist consultant approvals

From single-room structural transformations to full house refurbishments, we work from approved drawings to deliver high-quality, durable finishes.
Houses
Complete House Refurbishment
Renovation across multiple rooms or an entire property, coordinated from initial strip-out to final handover.
Apartments
Apartment Refurbishment
Interior renovation coordinated around building management regulations, lift access and logistics.

Heritage

Getting the Space Ready for Business
Commercial construction has another priority: the premises need to work when the doors open.
Oraanj undertakes selected interior refurbishment and commercial fit-out projects where programme reliability and craftsmanship are vital to opening on schedule.
Workplace

Specialist commercial requirements (licensing, fire safety, MEP) should be developed and approved before or during the fit-out programme.
Before We Price the Works
What Makes a Construction Quote Meaningful?
A quotation is only as useful as the information behind it. If one contractor prices a basic specification and another assumes premium materials, the figures aren’t directly comparable.
Scope
Defined Scope of Works
Exactly what work is included in the project boundaries, what is being stripped out, and what structural elements or existing fabric are retained.
Drawings
Technical Drawings & CAD
Clear floor plans, elevations, lighting plans, electrical circuits, and joinery drawings required for contractors to price and build from.
Spec
Material Specification
Defined selections for sanitaryware, kitchen cabinetry, worktops, flooring types, timber mouldings, paint grades and specialist finishes.
Programme
Site Conditions & Programme
Target handover dates, building management rules, access restrictions, working hours, and procurement lead times for bespoke items.
What Happens Before Construction Starts?
A clear, disciplined 4-stage sequence to eliminate ambiguity before physical works begin.
Project Information & Site Review
Stage 1: Review
We review the property and available design information in detail, conducting a site visit to assess existing structural fabric and access conditions.
Technical Audit & Information Check
Stage 2: Audit
We identify whether critical CAD drawings, MEP layouts, structural engineering calculations or specialist consultant reports are missing.
Scope of Works & Costing
Stage 3: Pricing
The proposed construction and refurbishment requirements are clearly defined, providing the rigorous basis for developing an accurate contractor quotation.
Procurement, Programme & Pre-Start
Stage 4: Launch
Long-lead items are scheduled, building management licences and party wall notices confirmed, and trade sequence aligned before site works commence.
What Happens on Site?
The physical sequence of construction from initial preparation to final handover.
Preparation, Structure & First Fix
Preparation
Existing interior stripped back per agreed scope.
First-Fix Works
Electrical cabling, plumbing and MEP infrastructure.
Internal Construction
Approved alterations and partition framing.
Kitchens, Bathrooms & Joinery
Kitchens & Bathrooms
Installation coordinated with services and tiling.
Bespoke Joinery
Fitted cabinetry, wardrobes and bespoke storage.
Flooring & Decorating
Hardwood floors, plastering and fine decorating.
Fittings, Commissioning & Handover
Lighting & Fittings
Luminaires, switch plates and hardware installed.
Final Installation
Sanitaryware testing, AV commissioning and styling.
Review & Handover
Snagging completed and keys handed over.
The exact sequence varies according to the property and project requirements.
Who Designed Your Project?
Whether your interior was designed by Oraanj or by an external architect, we provide seamless construction execution.
Designed by Oraanj
Keep the Design Connected to the Build
Where Oraanj has designed the project, our construction team works alongside the design and technical specialists responsible for developing your interior. Approved layouts, 3D finishes, lighting schemes and joinery remain tightly coordinated on site.
Designed by Someone Else
We Can Still Review the Construction Project
If another interior designer or architect has completed the design package, send us the available drawings. We can review documentation suitability, provide a transparent contractor quotation and deliver the works with senior director oversight.
Navigating London Buildings with Confidence
Apartments and heritage buildings present unique logistical and structural conditions that require seasoned contractor management.
Apartments
Construction in a London Apartment
Apartment refurbishment involves practical requirements beyond the works inside the property:
These items should be established before the project programme is finalised to avoid site delays.
Heritage
Refurbishing a Period Property
Older properties frequently reveal unexpected structural or fabric conditions once opened up:
A sensible programme allows for the fact that not everything is visible before strip-out begins.
Who Is Responsible for What?
Clear Responsibilities Make Construction Easier to Manage
A refurbishment involves several professionals. Clear role allocation ensures complete accountability across design, engineering and site execution.
Interior Designer
Develops concepts, layouts, materials, colours and furniture selection.
Technical Design Team
Produces agreed technical interior drawings, joinery details and lighting plans.
Structural Engineer
Calculates load-bearing wall alterations and structural steel requirements.
Specialist Consultants
Advise on party wall agreements, building control and acoustic testing.
Construction Team
Delivers the physical works on site, coordinating trades, safety and craft.
Project Manager
Coordinates programme milestones, communication, deliveries and procurement.
The exact appointments and responsibilities should be established for each project rather than assumed.
Cost & Timeline Considerations
Understanding the variables that influence construction budgets and programmes in London.
Cost Drivers
How Much Does Interior Construction Cost in London?
There isn’t one meaningful price per square metre for every refurbishment. Costs depend directly on existing condition, structural changes, bespoke joinery and selected material tiers.
Sequencing
How Long Does Interior Construction Take?
A room-by-room update differs significantly from a whole-property transformation involving extensive alterations. Timelines are determined by access, approvals, material lead times and specialist trade sequencing.
