The bold and expressive form of Penrith Peaks skilfully contrasts strong horizontal lines with a soft curve, and transparency with closed recessive elements. The dwelling presents as a refined object in its suburban setting and the design gestures are well executed. Careful arrangement of both interior and exterior space in response to the site constraints allows a constant visual connection with the landscape. A combination of crafted details, expressed materials, and subtle textures create a sense of joy when moving through the house.
