Garden Room Extension
Bathwick · Side & rear
Single-storey wraparound for a Georgian terrace, opening a tight kitchen onto a south-facing garden.
A small architectural practice in Bath, designing extensions, lofts and new builds for families across the West Country. Considered drawings, fixed planning fees, and a phone that someone always answers.

Widcombe · Rear glass box
Steel-framed glazed pavilion behind a Victorian villa, with a careful brick palette to match the original.

Full loft conversion drawing two new bedrooms and a family bathroom from an unused roof void.

Lansdown · Listed consent
Interior layout reworked across three floors of a Grade II townhouse, hand-in-hand with conservation.
We keep our service list short, because we'd rather do these six things properly than spread ourselves thin.
Single and double-storey extensions designed around how the family actually uses the house.
Drawn, planned and detailed — dormers, hip-to-gable, and full rooftop reworkings.
Bespoke houses on infill plots and replacement dwellings across Bath and the surrounding villages.
Sensitive work to listed and conservation-area homes, with the planning conversations handled for you.
Reworking how a home flows — not a full extension, just the right walls in the right places.
Fixed-fee packages from feasibility through to validated planning submission. No surprises.
Most clients have never worked with an architect before. So we use the RIBA Plan of Work — the same seven stages every UK practice follows — to keep the journey predictable.
A site visit, a measured chat about what the house needs to do, and a written feasibility note.
Two or three sketch options, drawn to scale, so you can choose the right direction before we go further.
Planning drawings, design & access statement, and pre-application advice where it makes sense.
Building Regs drawings, specification, and help running a fair tender with two or three trusted builders.
We stay involved through the build — site visits, instructions, and answering the questions the builder will ask.
“We'd had two bad experiences before finding Hearth. The drawings were clear, the fixed fee was a relief, and they spoke to the planners on our behalf — we just got on with our lives until permission came through.”
The first conversation is free, in person at the studio or at your home. We'll tell you honestly whether the project is worth taking forward — and what it's likely to cost in design fees and on site.
