Q's House, 42 Roupell St, London

It looks like Q's home in the movie No Time To Die is located at 42 Roupell St, 42 Roupell St, London SE1 8TB, UK.

This address can be seen on a promotional behind the scenes set photos showing James Bond (Daniel Craig) and Moneypenny (Naomie Harris) arriving in the Cumberland Grey Aston Martin V8 and waiting in front of the door with number 42 on Roupell Street in London.

In the trailers we have already seen James Bond and Moneypenny visiting Q (Ben Whishaw), so we can assume these photos are from that same scene.

The house on Roupell Street is near Waterloo Station.

The building is an early-mid 19th century terrace of two storey, two window cottages. Stock brick with gable shaped stone-coped parapet front. Gauged flat brick arches to sash windows with glazing bars. Six panel doors, with cornice head and plain fanlight, under round gauged brick arch. Interior features include original staircases, dado rails and round arches on moulded consoles over hallways.

According to online records, the building last sold on 6 September 2006 for  £615,000. Currently the building is probably worth close to £1.4m, as similar houses in the same street have sold for £1.2m - £1.4m in 2016 - 2018.

For items in Q's room, like his laptop stand, drinking mug and more, see an overview here.

Note that the indoor scenes of the home were most likely not filmed in the building but on a set.
