Extensions

Extending homes to create the space people actually need — from larger kitchens and open-plan living areas to additional bedrooms and dedicated family spaces — across Hertfordshire, Bedfordshire and London.

A growing family, a cramped kitchen, a lack of living space — an extension is about creating more room without simply adding square footage for the sake of it. It's about understanding how a home is used, then designing and building an extension that makes the whole property work better.

It's rarely straightforward. Foundations, structural alterations, drainage, rooflines, planning conditions and connecting new work to the existing building all have to line up. That's the part we're built for — the technical judgement calls that keep a project on schedule and on budget, not just the finish photos at the end.

Whether it's a single-storey rear extension, a side return, a wraparound extension or a full two-storey addition, the goal is always the same: create space that feels like it belongs. From the initial assessment through to the final details, we coordinate the work around how the home needs to function, making sure the extension is practical, compliant and built to last.

How an extension runs

Four stages, one point of contact throughout — no handoffs between separate contractors.

01

Survey & feasibility

We assess the structure, check what planning realistically allows, and flag risks before you commit to anything.

02

Design & planning

Layout, structural drawings and the paperwork side — building regs, planning submissions.

03

Build

Structural work first, then fit-out. One site team, one schedule, weekly progress updates.

04

Handover

Snagging, certification and documentation handed over — the space is ready to use, not just ready to look at.
