You see your finished extension in complete 3D detail before a single wall goes up. From that point, one team manages every stage of the build under one contract until we hand back your keys.
Book Free ConsultationA home extension is one of the most significant investments a homeowner makes, and the firm you choose to deliver it matters more than most people realise.
At Nureno, every extension begins with a complete 2D and 3D visualisation of the finished space. You see every room, every finish and every structural detail before anything is agreed. Both parties sign off on the same design before a single wall goes up. What you approve is what gets built.
From the initial design brief through to the final handover, one team manages every element of your extension under one contract. No separate contractors to coordinate, no gaps in responsibility and a fixed price agreed before any work begins.
Get Your Free ConsultationWHAT WE DELIVER
A fully-procured extension service covers every element of your project from design through to aftercare. Planning, structural engineering, procurement, construction and handover, all managed by one team with one fixed price and one point of contact throughout.
You see your finished extension in complete detail before any work is agreed. Every room, every finish, every structural element confirmed upfront.
We assess whether your project requires full planning permission or falls within permitted development rights and manage the application either way.
All structural elements designed and engineered to full UK Building Regulations standard, backed by a 10-year insurance-backed structural warranty.
A named project manager coordinates every trade and every stage of the build from the first day on site to the day we hand back your keys.
Every extension closes with a full walk-through and a 24-month workmanship warranty. We remain accountable long after the keys are handed back.
THE NURENO DIFFERENCE
22% of build projects end in dispute. Ours do not. Before any work begins, both parties sign off on the same complete 3D design of the finished extension. Every room, every finish and every structural detail is documented and agreed. What you approve is exactly what gets built.
The visualisation stage is not an optional extra. It is the foundation of everything that follows. It is what makes the fixed price possible, the programme predictable and the finished result match what you had in mind when you first made contact.
When both parties are looking at the same detailed design before work begins, there is no room for misalignment. The dispute never forms because the conditions for a dispute were removed at the design stage.
THE DESIGN FEE
How the design process works depends on where you are starting from. If you already have architectural plans, we price from those and design your interiors as part of the project. If you are starting from scratch, we charge a design fee that comes off your final bill if you proceed. Either way, you own the design outright and are free to take it to market if you wish. You are never locked in.
