Castlewood House

 The existing building will be demolished, with the erection of an 11-storey office building (Class B1) with retail and restaurant uses (Class A1/A3) at ground floor level; enlargement of existing double basement level and formation of roof terraces and rooftop plant along with associated highways, landscaping, and public realm improvement works.

This will create a stunning new office building, along with new public routes and spaces linking Fitzrovia to Covent Garden, flanked by shops, cafes and restaurants.

Medius House

Medius House will ensure the delivery of new affordable homes, while retaining its Grade II-listed façade. Additionally, there will be the addition of a two-storey roof extension including private roof terrace.

Medius house will change from office (Class B1) and retail (Class A1) to provide 20 affordable housing units (Class C3) at upper floor levels with retained retail use at ground floor level.
