Full Design & Build Service in London | Turnkey Design
Can one company handle design and construction together?
Yes. Our Full Service Interior Design London approach is built to manage everything from concept to completion. Instead of working with separate designers, contractors, and suppliers, you have one coordinated team responsible for design, sourcing, and execution.
What does a design and build company actually do?
A design and build company manages the full project — including layout planning, technical drawings, material selection, procurement, and construction coordination. Through our Turnkey Interior Design London process, every stage is structured before work begins, reducing uncertainty and improving overall project control.
Is design and build better than hiring separate contractors?
In most cases, yes. When design and construction are handled separately, gaps in communication often lead to delays, errors, and costly changes. A unified approach ensures that design decisions, specifications, and build requirements are aligned from the start.
Who manages the entire renovation or fit-out project?
We manage the entire process — from design development to final installation. As a construction company in London working alongside our design team, we coordinate contractors, suppliers, timelines, and on-site decisions so you are not left managing the project yourself.
How long does a full design and build project take?
Timelines depend on the scale and complexity of the project. A typical full-service residential renovation or commercial fit-out can range from several weeks to a few months. With a structured design and build company London approach, timelines are planned in advance to minimise delays during construction.

Is Full-Service Interior Design Right for You?
This service is designed for clients undertaking serious renovation projects — where layout, construction, and joinery must work together.
It is ideal if:
You are planning a full home renovation or refurbishment in London
You require bespoke joinery London integrated into the design from the beginning
You want a turnkey interior design London solution with full accountability
You need one team managing design, build, and execution
You want to avoid on-site decisions, delays, and costly mistakes
If your project is limited to furnishing or styling only, a lighter design package may be more suitable.
One Team. One Responsibility.
Most clients don’t start by looking for a design and build company. They start because the process feels overwhelming, fragmented, and risky.
- “I don’t want to deal with multiple contractors”
- “I’m scared something will go wrong”
- “I don’t have time to manage the project”
- “I don’t trust builders and designers working separately”
- “I want one point of responsibility”
These are not small concerns — they are exactly where most renovation and fit-out projects start to fail.
When design, sourcing, and construction are handled by different teams, responsibility becomes unclear. Decisions are made in isolation, communication breaks down, and the client is left coordinating everything.
At Oraanj Interior Design, our Turnkey Interior Design London approach is built to remove that complexity.
We act as one integrated team — managing design, procurement, and construction together — so you are not chasing updates, resolving conflicts, or managing multiple contractors.
You have one clear process, one coordinated team, and one point of accountability from concept to completion.

Full-Service Interior Design FAQs
In many cases, yes. When design and construction are handled separately, communication gaps can lead to delays, inconsistencies, and costly changes on site. A design and build approach keeps the process more aligned, with one team overseeing design intent, technical detail, and execution together.
The cost of full service interior design in London depends on the size of the property, the level of renovation involved, the amount of bespoke work required, and the overall specification. What matters most is having the project properly planned from the start, as this helps control budget, reduce rework, and avoid expensive mistakes during construction.
In a full-service project, we manage supplier coordination, builder communication, procurement timelines, and key site decisions so the project moves forward in a more organised way. This reduces the pressure on the client and creates a clearer process from design through to delivery.
Yes. Our full-service approach is designed to manage the entire journey, from initial concept and space planning to technical drawings, procurement, contractor coordination, and final handover. This gives clients one point of responsibility instead of multiple disconnected teams.
If you are renovating an entire home, it is important to work with a team that can coordinate both the design and the build. Our <a href=”https://www.oraanj-interiors.co.uk/full-service/”><strong>Full Service Interior Design London</strong></a> approach is structured for full-home projects where layout, joinery, procurement, and construction all need to be resolved together.
Turnkey interior design typically includes concept design, space planning, technical drawings, materials and finishes, procurement, contractor coordination, site oversight, installation management, and final styling. The aim is to provide a complete, managed process so the client does not have to coordinate each stage independently.
The right company should offer more than just contractors or drawings. They should be able to plan the layout properly, resolve technical details before construction starts, coordinate procurement, manage timelines, and take responsibility for delivering a cohesive result. A strong design and build team reduces confusion, improves accountability, and makes the process far easier to manage.
