A Grade II listed terraced property, No. 22 Grosvenor Gardens has been transformed from its previous use as a sixth-form college to a high-specification modern workspace with its period features restored.
The building, in the Grosvenor Gardens Conservation Area of the City of Westminster, forms part of a grand Victorian era terrace developed from elevations by Grosvenor Estates Architect Thomas Cundy III in the 1860s. The accommodation was originally spread across the ground and four upper floors, with generous subservient attic and basement spaces which had previously been adapted for use. Structural alterations included a new lift and service core and contemporary rear extension.
The thermal efficiency of the 150-year-old building fabric has been dramatically improved, which is a first for a Grosvenor Estate; reducing airtightness to 8m3/hr-m2 and annual carbon expenditure to 24,409 kgCO2/m2yr, representing a 42% saving.
