Bay & Bow Windows designed around sash-heavy period stock, communal-window agreements and RBKC / Camden conservation planning.
Barnes is a village within London — Georgian and Victorian frontages around the Pond, Arts-and-Crafts homes along Castelnau, and river-facing family houses. We install throughout SW13 with heritage sightlines matched.

What sets our bay & bow windows apart in Barnes.
Structural Corner Posts
Steel-reinforced bay posts carry the load above — essential for 45° splayed bays and box bays that support first-floor masonry.
3-, 4- & 5-Facet
Splayed bays for Victorian terraces, box bays for Edwardian semis and shallow bows for cottages — all built to your survey template.
Lead-Lined Roofs
Traditional lead-flashed or GRP roofs matched to the existing bay, with proper flashing back to the brickwork and stepped over the parapet where required.
Replacement in a Day
In most cases we remove the tired 60s or 70s bay and refit the replacement inside a single working day — no exposed brickwork overnight.
Heritage or Modern
Traditional splayed bays with astragal bars and dummy sashes, or clean contemporary square bays in aluminium — matched to the age of the property.
Kerb Appeal
The single most valuable retrofit for a Victorian or Edwardian terrace — a restored bay adds visible property value and lifts the entire façade.

"A 6.4m aluminium bifold set across the rear of our garden flat. Slim sightlines, perfect thresholds, and the team left the house cleaner than they found it."
"Sprayed a bespoke Farrow & Ball green on our composite front door. The finish is glass-smooth and the security spec exceeds our insurer's PAS 24 requirements."
