Hyde + Hyde unwraps copper box add-on to Cardiff home

  • Comment

Hyde + Hyde Architects has completed this copper and oak extension to a 1930s home in Cardiff, south Wales

The 73m² addition to the rear of the home was part of a larger, £350,000 overhaul of the property which included replacing curved glass windows.

According to the six year-old Swansea and Cardiff based practice, the ‘contemporary extension’ appears as ‘a simple box peeping above the layers of existing green glazed tiles of the existing home’ when viewed from the front.

The extension features a number of ‘overhangs, cantilevers and canopies to shelter its occupants from the persistent Welsh rain’ and is linked to the main house through a single storey glazed ‘living and entertaining space.’
