Case Study 01SE22 — East Dulwich

We were about to list the house. The estate agent had already been round. Then we looked up.

Rachel & Will

SE22 · Victorian terrace · 3-bed

Rachel and Will had outgrown their East Dulwich terrace after their second child arrived. The back bedroom had become a junk room. Moving meant losing their street, their daughter's school, their local. They called us instead.

The roof pitch was generous — 2.4 metres at the ridge. We installed two Velux Conservation windows on the rear slope, a fixed skylight over the stairwell, and lined the new room in pale oak. Total build: eleven weeks.

Daniel P.

N16 · 1930s semi · 4-bed

Daniel needed a home office that closed. His 1930s semi in Stoke Newington had a hipped roof — not ideal, but workable. We converted the hip to a gable, pushed a full-width rear dormer, and fitted a proper office with a separate desk alcove and a single-piece Crittall window looking over the garden.

The en-suite — his wife's condition for the project — went in the eaves behind the staircase. Underfloor heating, a rain shower, and a brass-framed mirror that catches the afternoon light.

Case Study 03E3 — Bow
"

We wanted a master suite. A proper one — with a dressing room, an en-suite, and enough ceiling height to stand up in.

Kemi & Oluwaseun

E3 · Victorian terrace · 3-bed → 5-bed

Kemi and Oluwaseun's Bow terrace had a long rear garden and a generous roof pitch — the conditions for an L-shaped dormer. We took the full rear slope and wrapped around the side return, creating 48 square metres where there had been 8.

The master bedroom sits under the rear slope with a full-width zinc-framed window looking over the garden. The dressing room occupies the side return, lit by a fixed Velux. The en-suite — slate floor, freestanding bath, brass fittings — is tucked into the rear corner where the original hip used to be.

Planning took nine weeks. The build took seventeen. They moved in on a Thursday. Kemi sent us a photograph of the bath, full, with the roof window open above it. We framed it.

What this project proves

A full L-shaped dormer on a standard terrace can add two bedrooms, a bathroom, and a dressing room — typically adding £120,000–£180,000 to the property value in inner London.
