The practice is currently designing the scheme, which will eventually be built on a site neighbouring the Pakistani city of Islamabad.
The project - Green Terraces One - will cover approximately 50ha and comprise 500 plots of different sizes. It will be positioned on a very steep, rocky hillside about 500m above sea level.
The development will be aimed at Pakistani expatriates returning to the country after working abroad.
Woods Bagot claims that the designs take their 'inspiration' from Frank Lloyd Wright's masterpiece Fallingwater.
The practice's European managing director Stephan Reinke said: 'This is a monumental challenge from an architectural point of view, but one which we are confident that through our strong international heritage and aspirational design culture we will successfully conquer.
'The natural beauty of the Himalayan landscape married with the innovative design of each individual residence offers a unique lifestyle experience.
'We are delighted to have been selected to work on such an inspirational, innovative and ambitious project,' Reinke added.
