Hope View House
Download
as PDF Built into a steeply sloping site, this elegant forever-home maximizes the panoramic views of the surrounding countryside in an Area of Natural Outstanding Beauty.The site has a collection of Listed Buildings at the base of the hill prone to flooding. A Paragraph 55 exception dwelling was required to unlock planning policy, and Passivhaus was set as a statement of intent at planning stage.There are three key components to the concept: trees, meadow, house. The upper part of the site has been planted by the clients with over 1200 deciduous trees, whilst the lower part of the site has been replanted as wildflower meadow and orchard. The long and low south facade, a horizontal accent in the hillside, draws an 85m line of stone between the two landscapes just as the neighbouring dwellings across the valley do. As the local stone craftsmanship is such a key feature of the design, keeping the stone masons happy was an important task on site.
