An additional porch can improve the resident’s experience of their home. It adds internal space for storage of coats and shoes thus freeing up cluttered hallways of terraced social housing with a typical internal area of 65 sq m. As each unit is made to order the design can be tweaked to best fit the building archetype and street it is being installed on. YESporch is fitted with a Passivhaus specification door.
