Case Studies

Real homes. Real numbers.

Every project below was measured, made and installed by us — never subcontracted. Full specification, timeline and outcome.

Case 01 · Hampstead, London

A Victorian townhouse rescued from failing sashes

A four-storey Hampstead townhouse in a conservation area, with 18 draughty timber sashes and a tired original front door. The brief was heritage aesthetics and modern thermal performance without triggering a planning objection.

Case 02 · St Albans, Hertfordshire

A rear extension opened up with 6m of aluminium bifolds

A single-storey rear extension on a 1930s semi. The clients wanted the kitchen-diner to feel continuous with the garden — but the wall run also needed to hit modern thermal performance and take a family of four's daily wear.

Case 03 · Marlow, Buckinghamshire

A Grade II Georgian frontage restored with slimline sashes

A Grade II listed Georgian house on Marlow high street with 12 original single-glazed sashes, several beyond economic repair. The listing officer wanted a solution that preserved sightlines exactly while lifting thermal performance.

Case 05 · Harpenden, Hertfordshire

A year-round garden room studio in Harpenden

A 6m × 4m garden studio for a client working from home four days a week. The brief demanded true year-round comfort — not a summerhouse — with a 4m sliding door opening to a new patio.

Case 06 · Beaconsfield, Buckinghamshire

A lantern-roof orangery extending a Beaconsfield kitchen

A 5m × 4m orangery added to the rear of a 1980s executive home. The client wanted a light-filled kitchen extension with the substance of a masonry room, not the feel of a conservatory.
