Aluminium Bi-Fold Doors in Westminster

Space is precious in Westminster, so our aluminium bi-fold doors work hardest where it counts — opening mews houses onto courtyards, connecting garden flats to their patios and dissolving the wall between roof terraces and living space across Belgravia, Marylebone and Pimlico.

Bi-fold doors made for Westminster homes

Westminster's homes rarely have sprawling gardens, which makes a well-designed bi-fold even more valuable. Here the openings we transform are courtyards behind Belgravia mews houses, the patios and lightwells of Pimlico garden flats, and the roof terraces of Marylebone and Maida Vale mansion flats. In every case, the slim aluminium frames and expansive glass make a modest outdoor space feel like a genuine extension of the room.

Given the density of listed and conservation-area housing, we focus these installations on rear and internal elevations where change is far less sensitive. Thermally broken profiles, laminated glass and multi-point locking bring modern warmth and security to homes whose front windows must stay untouched.

Why aluminium

Slim frames, wide spans, year-round warmth

Thermally broken aluminium is strong enough for the wide openings Westminster homes are known for, yet slim enough to keep sightlines minimal and glass maximised. Low-E double glazing, weather-rated thresholds and multi-point locking mean the doors look after comfort and security as well as light.

How Westminster homeowners use bi-fold doors

Every set is designed around the way Westminster homes are built and lived in.

Belgravia mews courtyards

Two- and three-panel bi-folds open the rear of mews houses onto private courtyards, bringing light deep into the plan.

Roof-terrace mansion flats

Slim bi-folds create a seamless link between a top-floor living room and a Marylebone or Maida Vale roof terrace.

Garden-flat patios

Pimlico and Bayswater lower-ground flats gain a bright, patio-facing kitchen or living space with a full-width set.

Maximum light

expansive glass and slim sightlines open the room to the garden

A-rated warmth

thermally broken frames and low-E glass for year-round comfort

Period windows to keep warm and quiet?

Many Westminster homes sit in conservation areas or are listed. Our discreet, reversible secondary glazing cuts heat loss and noise while keeping your original windows exactly as they are.
