Adria Boutique Hotel, London, UK

The latest project from Al Rayyan Hospitality is a sister to the Doha-based Arumaila boutique hotel. Its Grade-II listed Victorian townhouse in west London was restored by design consultant Urban Velvet who appointed Jestico + Whiles to work on the architecture and the interiors. The grand staircase and the lounge fireplace have both been preserved, while 1950s-inspired decor elsewhere features bespoke lighting. The 24 rooms are not numbered but rather make British references to 'Croquet' and 'Downing'. The public spaces include a spa, gym and library, and there's a personal butler assigned to every room.
