Extensions & renovations
More space, and a house that works better for it.
Extensions and larger renovations succeed or fail on planning. We help you get the drawings, approvals and programme right, then manage the build so you always know what's happening next and what it costs.
A good fit for
- Single-storey rear and side extensions
- Knocking through and reconfiguring rooms
- Renovating a house you've just bought
- Refurbishing period properties
- Work that combines several rooms at once
What we do
From first visit to handover.
- 01
Early advice
Before you commit to drawings, we talk through what's realistic for the house, the budget and the timescale.
- 02
Drawings and approvals
We work with your architect or designer, or introduce one, and help with Building Regulations and planning where they apply.
- 03
A clear written quote and programme
The build broken into stages, each priced, with a programme showing what happens when.
- 04
Managing the build
Groundworks to plastering, coordinated by one project manager, with regular updates as each stage is completed.
- 05
Plumbing, heating and finishing
Our sister company, Greens Heating & Cooling, can design the heating for the new space, so it's comfortable from day one.
- 06
Completion
Sign-off, a final walk-round and the certificates you'll need when you come to sell.
Good to know
Permissions come first
Most extensions need Building Regulations approval, and some need planning permission. Listed buildings and conservation areas, common in Bath, can need extra consent. We'll tell you what's likely to apply at the first visit.
Budget for the unknowns
Older houses can hide surprises once walls and floors are opened. We'll recommend a sensible contingency and explain how any changes are agreed before they're done.
Heating the new space
An extension changes how much heat the house needs. Planning radiators or underfloor heating early avoids cold rooms and costly changes later.
Questions
What size of project do you take on?
Most of our projects are between £5,000 and £50,000, from a single room to a full renovation.
Do I need an architect?
For most extensions, yes: you'll need drawings for approval and for us to price accurately. We can work with yours or recommend one.
How do payments work?
Payments are staged as the work progresses, agreed in writing before anything starts. You won't be asked to pay for work that hasn't been done.
