House extensions at 3 Southdean Gardens, Wimbledon, London SW19

“This householder application proposes alterations including the erection of a single storey rear extension, and two storey side extension to the rear half of the building, including the infilling of the stepped flank wall and new windows; the erection of a rear mansard roof extension to the main roof with dormer windows and French doors and safety railings; and the replacement of the existing flat roof over the front ground floor bay and porch with a pitched roof.”

“The proposed single storey rear extension would measure 4.2m in width, 4.0m in depth on the eastern side and 7.8m in depth on the western side. The proposed extension would have a part flat, part pitched roof measuring 3.2m in height on the eastern elevation and an eaves height of 2.6m on the western elevation measured from the garden level of the subject property. The proposed extension would have an additional 0.2m high parapet on the rear and eastern elevation.”

“The subject property is a two-storey (with roof accommodation), mid-terrace property located on the northern side of Southdean Gardens and has a small front garden and narrow rear garden. Similar two-storey terraced properties adjoin to the east and are located opposite the site to the south. A smaller two-storey property adjoins to the west and the Gardens Lawn Tennis Club is located to the north/rear of the site.”

“January 1971 (70/7339) Granted - Conditional: Conversion of dwelling into two self- contained units.”

“Official Official 5.1 In considering the above, overall, the proposed development would be of a design and scale that is considered appropriate in this context and location. The proposed additions would not result in an undue detrimental impact on the character and appearance of the subject property, neighbouring properties or the surrounding area and would be acceptable.”

“While the proposed single-storey ground-floor rear extension would result in some additional overshadowing and increased sense of enclosure for No.5 Southdean Gardens, it is not considered that this would be to an unacceptable degree and a reasonable level of outlook would be retained.”
