A huge custom Bi-fold door project combining beauty and comfort. This Montana mansion nestled among the mountains is a perfect example of a combination between nature and comfort. The big dining area is the main space of the house with the best position. Brombal designed a custom Bi-fold door system that curved around a unique custom radius to create an amazing wide-angle viewing area that let people enjoy a breathtaking scenery. Windows and doors finishing provide a contrasting combination of luxuriousness inside and a strong contact with the wild nature outside.
