Secondary Glazing for Hampstead Garden Suburb, Totteridge & Barnet's Metroland Homes
Barnet stretches from the Arts and Crafts masterpiece of Hampstead Garden Suburb through the Edwardian avenues of Finchley and Golders Green to the village greens of Totteridge and Mill Hill. Much of the borough's housing is interwar Metroland — generously proportioned semis with leaded casements and bay windows that were never built for warmth. Our secondary glazing brings these homes up to modern comfort standards while respecting the strict design controls that protect the Suburb and the borough's sixteen conservation areas.

Working in Barnet
Hampstead Garden Suburb is governed by both Barnet Council and the Hampstead Garden Suburb Trust, whose consent is required for virtually any visible change. Internal secondary glazing is one of the few thermal upgrades that routinely satisfies both, and we prepare Trust-compliant submissions as standard.

What We Solve in Barnet
Hampstead Garden Suburb Trust Consent
The Trust's design guidance strongly resists replacement windows. Our fully internal installations leave the elevation untouched, which is why they are consistently approved where uPVC is refused.
Leaded Light Casements
Barnet's interwar homes are full of small leaded lights that cannot be double glazed without losing their character. A single secondary pane behind the whole window preserves the leadwork and stops the draughts.
A1, M1 & Northern Line Noise
Properties near the Great North Road, the M1 approach and the open-air Northern line benefit from our acoustic laminate specification, which addresses sustained road and rail intrusion.
