This project uses design to maximise the play of light, volume and playfulness in the conversion of a victorian terrace family home. A decision was made to rebuild the first floor rear section in order to fully insulate these rooms. This allowed for clever engineering to minimise the thickness of the floor construction and provide more head height to the ground floor kitchen space below. The result meant the new ground floor extension feels very spacious. The steel structure was left exposed - providing an option to hang a swing or hammock. Large sections of glazing to the side and rear were added. The rear is north facing so the large sections of glass provide as much light into the rear living room as possible. The sun enters the roof lights in the morning and evening providing playful shadows across the walls without overheating the space. Large sliding doors do not impede into the garden but open up the space. The rear overhang allows the doors to be kept open in all weathers. The space has been kept playful with the addition of a magnetic plaster and blackboard wall. Extra storage has been built into the underside of the wide stairs. The lower hallway was enlarged to allow for a small WC, along with adequate space for coats and bicycles.
