Challoner House

Challoner House is a renovation project, converting and extending a locally listed building into high quality office space for an owner occupier, using natural and recycled materials.

Originally comprising two townhouses and an iron printing press, the building is situated in the heart of Clerkenwell Green Conservation area renowned for its architectural and historic interest. HUT were briefed to sympathetically transform, extend and thermally upgrade the existing building whilst preserving the building’s character and history.

The building was originally constructed from brick and timber and later, steel. Breathable materials of sheeps wool, wood fibre board, hemp and lime render were selected due to their low embodied carbon, thermal benefits and breathability. Internal walls are constructed using Fermacell selected for its recycled content, moisture control and fire resisting properties. The existing steel structure has been reused and repurposed to avoid unnecessary waste. The new butterfly roof is constructed using CLT with the vaulted, sculptural form and timber structure left exposed; creating a strong visual connection to the form and heritage of the original building.

The project commenced by undertaking studies to understand alterations to the building from the original plan form through to its current layout. The plan form is mapped out in brick pavers within the new offices whilst brick arches and historical patina are left exposed and are expressed within the renovation works. The result is a building which is contextual and of its place, celebrating the historical idiosyncrasies whilst significantly improving sustainability and operational carbon costs through the sensitive application of natural materials.
