  The proposal is: to extend the rear of the property's eastern section as a single floor, flat roof extension including roof light. The dimensions of the extension would be to extend out by 4000mm in depth, with a width matching the existing rear of the property, which would be 7291mm. The proposal would be to extend using the existing stone that would be recovered from the rear of the property and matching stonework for any remainder. The proposed elevations would be designed to match the existing wall, with the eastern, southern and western sides of the elevation using proposed stone elevations to match the existing, lintel details to match existing, and the installation of bi-fold doors. The proposal would be to use aluminium grey frames for the doors (which would be similar to those used in recent development of 1 Coombe Lea). The ground floor windows on the northern elevation and eastern elevation would be reduced in height (whilst maintaining existing lintel) - with the raising of the cill height. The windows would be deigned to match the extension at the rear, in addition to the replacement with matching windows and frames throughout property. Internally, the proposal would involve 1) the removal of internal walls between the reception, study and sitting room, and transfer of the kitchen into this open plan area; and 2) insertion of wall between family room and existing kitchen, insertion of a space within existing kitchen and expansion of utility room by removing existing walls.
