Premium Window Installation in Marylebone, London

Marylebone is covered by several conservation areas including the Portman Estate and Harley Street areas. Westminster City Council requires replacement windows to match original Georgian or Victorian designs in timber. Many properties are managed by the Howard de Walden and Portman estates, which have their own window specifications.

The Howard de Walden and Portman estates manage much of Marylebone and have specific requirements for window replacements. We work regularly with both estates' surveyors and can advise on their approved specifications. Estate consent is needed alongside any planning permission requirements.

Marylebone's proximity to busy roads like Baker Street and Marylebone Road makes acoustic glazing valuable. We offer triple glazing and asymmetric laminated double glazing achieving 40-45dB noise reduction. Secondary glazing is an excellent option for listed buildings on noisy streets.
