Extensions

The best value space you will ever add is the space already sitting behind your kitchen wall. We design and build extensions that feel original to the house, not bolted on.

Most of our extension work is on Victorian and Edwardian terraces, 1930s semis and postwar houses, so we know where the awkward drains hide and how party wall agreements really play out. We handle the structural openings, steels and underpinning in-house, and we sequence the messy work early so your household is disrupted for weeks, not months.

Every extension is priced as a fixed, itemised scope. Glazing, floor finishes, underfloor heating and kitchen fit are all specified before we start, and any change you ask for is priced in writing before it happens. That is how the final bill stays the same as the first one.

Why it works

How we keep extensions on track

Design handled

Work with your architect or ours. Planning applications, permitted development checks and building control sign-off are all managed for you.

Party wall experience

We prepare the groundwork for party wall agreements early, so notices to neighbours never become the thing that stalls the job.

Weather-tight fast

We programme the shell first: foundations, structure, roof, glazing. Once the envelope is sealed, the trades inside are not hostage to the forecast.
