The design-led approach to home extensions.

A 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.

WHAT WE DELIVER

Every element of your extension. One team, one contract, one outcome.

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.

Full 3D Visualisation

You see your finished extension in complete detail before any work is agreed. Every room, every finish, every structural element confirmed upfront.

Planning and Permitted Development

We assess whether your project requires full planning permission or falls within permitted development rights and manage the application either way.

Structural Design and Engineering

All structural elements designed and engineered to full UK Building Regulations standard, backed by a 10-year insurance-backed structural warranty.

Full Project Management

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.

Aftercare and Warranty

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

See it before we build it.

Why visualisation is the single most important step in any extension.

Most extension disputes do not start on site. They start in the gap between what a homeowner imagined and what a builder understood they had agreed to deliver. Plans that left too much to interpretation. Verbal agreements that meant different things to different people.

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 6-Step Process

Our Process. Six Stages,
No Surprises.

Every Nureno project follows the same six-stage process. Designed to give you complete clarity at every decision point and to ensure nothing gets built until you have seen it, approved it and signed off on a fixed price.

01

Free Consultation

We visit your home, listen to your brief and give you an honest view of what is achievable within your budget. No obligation and no sales pitch.

02

Feasibility

We assess layout possibilities, planning requirements and structural considerations. Ideas become a clear, properly costed plan.

03

Design and Visualisation

Our in-house team produces complete 2D plans and 3D renders. You see every detail before work begins.

04

Fixed Proposal

Once the design is signed off we produce a detailed fixed-price proposal covering every element. Transparent pricing, clear timelines, no surprises.

05

Expert Build

Every trade, every material and every detail coordinated under one contract by a named project manager from day one to handover.

06

Aftercare

On completion we walk through the finished project with you and hand it back with a 24-month workmanship and 10-year structural warranty.

THE DESIGN FEE

Transparent from the start.

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.

Do you have architectural plans?

We price from your existing plans and design your interiors as part of the extension project. No design fee is charged. Interior design is included as part of the full project scope.

We manage the full design process, from the initial brief through to complete 2D plans and 3D visualisation of your extension. A design fee applies, which comes off your final bill if you proceed. You own the design outright.
