Tigg Coll Architects took a new approach to a straightforward town house renovation and expansion in London. The home’s rear extension has its own personality, with with pivoting glass doors, sharp red support beams, and a wood-burning fireplace. The overhanging concrete plinth acts as a hearth or, as Tigg imagines it, a sort of contemporary inglenook. Wood piles neatly between the beam and wall. The fireplace, a Stovax Riva 2, is flanked by a Lampe Gras wall lamp; firewood is cleverly stored in the narrow space between the fireplace and the red support beam, creating a fun moment of practical texture in the room.
