Bath Square – VELFAC V200

Situated in the heart of Old Portsmouth, Bath Square is an eighteenth-century property just moments from Portsmouth Harbour. As part of a major refurbishment, the project team removed the existing roof structure and replaced it with a timber-framed Mansard roof. This created additional accommodation and opened up views across the harbour and Solent.

The project presented several challenges, including restricted access, limited storage space and the complexities of extending a Grade II listed building. The design team carefully considered how the new structure could respect the character of the original property while creating a modern living environment.

Westcott Architectural Glazing supplied and installed bespoke VELFAC V200 composite windows and glazed French doors throughout the new extension. The team finished the units in RAL 7016 Anthracite Grey. They selected the outward-opening VELFAC windows to provide a contemporary look while complementing the historic character of the property. The slim frame profiles maximise natural daylight and help frame panoramic coastal views from the new living spaces.

The glazed French doors provide direct access to a new roof terrace. This creates a strong connection between the interior and exterior while making the most of the property’s elevated position overlooking Portsmouth Harbour.

The new upper floor accommodates a master suite with an en-suite bathroom and bespoke storage crafted from reclaimed materials. The completed project combines historic character with modern glazing solutions. It transforms an underused roof space into a bright, practical and visually connected living environment.

Ideal Home magazine featured the project in its January 2016 issue. The project also received a Best of Houzz Award for Design, recognising the quality of the transformation and attention to detail throughout.
