This Islington house extension transforms a property on Gibson Square, a Grade II listed garden square in Barnsbury. The works included an extension at lower ground floor and full refurbishment of the existing spaces.

The challenge at lower ground floor was to create flexible spaces for work, which could also be converted to guest bedrooms when required. This was achieved with fold out beds integrated into new joinery, and a compact guest bathroom. Large format terrazzo tiles unite the entire floor.

An oak panelled rear extension at lower ground provides a family room and generous wine store. Pivoting doors link to an excavated light well terrace, where stepped planters and projecting angled brickwork create depth and shadow.

At first floor, original Georgian plasterwork and timber details were carefully restored and redecorated, with the floor finished in a smoked oak herringbone parquet. A generous bathroom is created at second floor with a herringbone floor and large slabs of book matched marble.

This was a complex project that required careful preservation of original fabric and the sensitive insertion of modern services and finishes to current environmental and acoustic performance. A tube line running directly under the property necessitated a comprehensive underfloor acoustic and vibration dampening solution, with associated underpinning throughout the lower ground floor.
