Rooftop extensions offer a considered response to the limitations of dense urban environments, where expanding outwards is rarely possible and opportunities exist to build upwards.
Across London, IQ Projects has delivered bespoke glazing solutions for rooftop extensions that respond to structural, planning and heritage constraints.
At projects such as BAFTA in Piccadilly and Savile Row, glazing allows rooftop spaces to open up to panoramic views, while schemes such as Borough High Street and Pennybank in Clerkenwell demonstrate how new levels can be introduced with minimal visual impact within sensitive urban contexts.
Glazing plays a key role in shaping these elevated spaces, supporting how they perform and are experienced. Natural light, views, environmental performance and the relationship between interior and exterior all need to be carefully balanced to create spaces that feel open, functional and connected to the wider city.
