Devonshire Close City Of Westminster W1G 7BA
The proposal is for the internal refurbishment of 1 Devonshire Close, including the addition of a mansard roof extension. On the ground floor, the existing living room will be converted into a bedroom. The current kitchen space will be reconfigured to accommodate a new laundry room, coat cupboard, and bathroom, as well as a staircase providing access to the existing terrace patio. On the first floor, the existing bedroom and en-suite will be redesigned to create a spacious master suite, comprising a bedroom, en-suite bathroom, and dressing area. The hallway will be reconfigured to include a study and additional storage. From this hallway, a new staircase will lead to the second floor, where the new mansard roof extension will house an open-plan kitchen, living, and dining area.
Tracking, tags and letters are part of the paid plan. See what it costs. Searching and reading any record stays free.
