where did they film ex machina

The main filming locations for Ex Machina were a mix of real Norwegian landscapes/hotels and UK studio work.

Main answer: where they filmed it

• Juvet Landscape Hotel, Valldal, Norway – This striking, minimalist hotel stands in for Nathan’s secluded mountain retreat; many exterior and some interior shots were filmed here.

• Valldal / Valldalen valley, Norway – The surrounding valley and roads supply the lush mountain environment and approach shots to the estate.

• Sognefjord, Norway – Used for scenic natural landscape shots to emphasize the remote, dramatic setting.

• Briksdalen / Briksdal glacier, Jostedalsbreen National Park, Norway – Provides the glacier and hiking-area establishing shots, like the hike with Nathan and Caleb.

• Grønfossen Waterfall, Grøndalen, Norway – A key outdoor scene with Nathan and Caleb uses this waterfall area, east of the Juvet Hotel.

Studio and city locations

• Pinewood Studios, Buckinghamshire, England (UK) – Most of the high-tech interiors (including the observation room and various corridors) were built and shot on stages here, matching the Norwegian exteriors with digital set extensions.

• Bloomberg offices, Finsbury Square, London, UK – These offices were used for Caleb’s workplace at the tech company “Blue Book.”

If you just want the ultra-short version: the “house” is largely Juvet Landscape Hotel and surrounding areas in Valldal, Norway, with interiors and extra shots done at Pinewood Studios in the UK.
