Sylvan Road, E11

New build detached house designed by Thiss Studio near Epping Forest in east London. A three storey, six bedroom house on a very tight site. The roof form is a complex double curve but formed entirely with straight parts. The roof finish is standing seam recycled copper. The street facing elevation also features a curved wall with rendered finish, the render comprised of different textured panels to break-up the surface. Bespoke window surrounds complete the facade.

This house showcases the ability to deliver complex designs using PH15 and still benefit from tried and tested junction details.

Aiming for Passivhaus Plus.
