The London Borough of Islington is one of over 30 planning authorities where we have successfully used our elegant slimline double glazing, that looks just like single glazing, on replacement windows and doors on conservation and listed buildings.

As specialists in timber windows and doors for period, conservation and listed buildings, we know exactly what it takes to secure planning permission to replace or restore windows on listed buildings, using a combination of bespoke, exact-match detailing that stays true to the heritage of the property, and modern upgrades such as slimline double glazing, which don’t compromise the look of the windows.

We have also been able to help our listed building clients in Islington put together successful planning applications – or listed building consent – by supplying full detailed CAD designs and hand-painted samples for council approval.

To have a look at our previous work, see our case study of this unique double glazed Grade II listed building in West London.

See the list of other authorities where we have successfully fitted slimline double glazing on windows and doors on listed buildings, which includes Greenwich, Westminster and Richmond upon Thames.
