Secondary glazing in Hampstead Garden Suburb

The housing in Hampstead Garden Suburb is largely Arts and Crafts houses, cottages and early 20th-century flats. Older cottages with small leaded or timber windows can keep their character with discreet secondary panels, hinged or removable so the originals stay accessible for maintenance.

For flats where the lease or freeholder prevents changing external windows, secondary glazing fitted inside is usually the simplest way to reduce traffic noise and heat loss. On listed buildings, secondary glazing is often the preferred way to improve comfort, but check with the conservation officer as listed building consent may still be needed.

Before any work, the Hampstead Garden Suburb Trust usually needs to give consent, and the area is a conservation area under Barnet Council. We review the Trust's design guidance with you at survey, so drawings and quotes are prepared with approval in mind.

Secondary glazing is a discreet second window fitted on the inside of your existing windows, leaving the originals untouched. It suits listed buildings, conservation areas, flats where external windows cannot be changed, and anyone wanting to cut noise and draughts without replacing period windows.

• Reduces draughts and outside noise
• Suitable where replacement is restricted
• Panels open or lift out for cleaning
