Harrow Roof Extension

Roof extension & loft apartment

Overview

A roof extension in Harrow transformed into a sophisticated open-plan loft — living, kitchen and entertaining in one cohesive layout under the eaves. Dark architectural finishes, warm oak and integrated lighting set a bold, urban atmosphere, balanced by soft neutral furniture and generous daylight from the dormer glazing.

The Brief

Challenge, approach, outcome

01

The challenge

A loft gives you the best light in the house and the worst geometry: sloping eaves that fight tall cabinetry, a plan that must hold living, cooking and entertaining in one room, and a dark palette that could easily turn a roof space into a cave by mid-afternoon.

02

Our approach

The awkward slopes were absorbed into the joinery rather than boxed away — dark wardrobe-height runs step down with the roofline, and the kitchen tucks its tall units into the full-height side of the plan. One warm oak spine carries the media wall, the slatted screen and the lit display niches, so the dark walls always have a glowing counterpoint. The wine wall was made the room's theatre — a full-height smoked-glass cabinet lit bottle by bottle — and the island doubles as the bar, so entertaining runs the length of the loft without moving a chair.

03

The client’s goal

A roof space that lives like a penthouse — bold after dark, bright by day, and one continuous room for a night that moves from sofa to bar without breaking.
