Westminster council is poised to approve Stiff & Trevillion proposals to refurbish and extend part of the Bush House complex on the Strand, adding a new roof terrace and rear colonnades to the rear of its south-west wing.

The practice’s plans were drawn up for developer Derwent London and would add around 4,000sq m of new space to the unlisted building, which is next to grade II-listed India House and immediately north of grade I-listed St Mary Le Strand Church.
