Mellior’s Hampstead care home conversion: design and planning notes for project teams

30 Second Briefing
Bentry Capital has bought the 23,456 sq ft Branch Hill House in Hampstead Village for £16.4m, planning a three-year conversion of the 1901 Edwardian baroque mansion and its 1.7-acre plot into No1 Hampstead, a gated scheme of about 50 premium apartments plus a standalone townhouse. The project will demolish the 1960s council-built wing and construct a new-build extension matching the original Sandringham-style façade, restoring period features throughout. Heritage specialist Stanhope Gate Architecture will revive and adjust the lapsed 2021 planning consent and optimise the one‑, two‑ and three‑bed lateral unit mix.
Technical Brief
- Existing Branch Hill House provides 23,456 sq ft of internal accommodation before reconfiguration.
- The freehold plot extends to 1.7 acres of landscaped gardens within Hampstead Village.
- Original mansion dates from 1901, designed by Ernest Flint with architect Henry Flitcroft.
- Camden Council’s 1960s care-home wing, now redundant since closure in 2015, will be demolished.
- New-build extension is intended to replicate the Sandringham-style façade and architectural detailing of the main house.
- Heritage specialist Stanhope Gate Architecture is retained to adjust the masterplan and optimise lateral unit layouts.
- No1 Hampstead forms part of Bentry Heritage, within Bentry Capital’s £500m GDV development portfolio.
Our Take
Within our 181 Infrastructure stories, north London schemes like No1 Hampstead are relatively rare compared with outer-London and regional projects, signalling that Mellior Group and Bentry Capital are operating in a more supply-constrained, planning‑sensitive submarket.
A three‑year build programme on a 1.7‑acre heritage site such as Branch Hill House implies prolonged interface with Camden Council on conservation and design details, which typically pushes contractors towards phased enabling works and early engagement on basement and tree‑protection strategies.
Bentry Capital’s £500m development portfolio GDV suggests No1 Hampstead is a mid‑sized asset within its book, so delivery risk is likely to be managed via standardised premium-residential specifications rather than highly bespoke one‑off detailing, even with Stanhope Gate Architecture involved.
