Overcoming a tight budget, constricted access issues, & sudden changes to the team, this triumphant urban infill delivers a compact light-filled comfortable home.The owners brief was centred on comfort and ease of use, but through her profession as a physiotherapist, it was clear that health was also very important; this made the Passivhaus approach an easy choice. Passivhaus Mews II accommodates three bedrooms, two bathrooms, a hydro-therapy pool and carport into the site of a double garage, at the back of the owners old house.
