The practice was granted planning permission for the home behind 13 Calmont Road in Bromley. Five previous applications to build on the site, which fronts onto Ambleside, were refused between 2015 and 2017.But planning officers assessing the latest proposals noted that the National Planning Policy Framework had a presumption in favour of sustainable development and that Lewisham was under-performing against housing completion targets.They concluded: The provision of one residential dwelling is welcomed and carries a significant planning merit. The standard of accommodation, design, impact on neighbours and the highway system, contribution to sustainable development and the environmental impacts are all considered acceptable, subject to conditions.AdvertisementGouldstone & Co said its single-storey scheme had been designed carefully to sit within the surrounding built environment, respecting the amenity of the existing dwellings and mature trees.The practice said its proposal was for a single family home designed around three courtyards that provided 50m of private amenity space accessible from all habitable rooms.The house also becomes quadruple-aspect, providing high-quality accommodation on a small site, it added in planning documents.Mature trees on the site will be retained and the new property will be set back from the pavement edge, with bedrooms at the back.Gouldstone & Co said the massing of the 97m scheme meant it would fit well within the tight site.AdvertisementThe ridge of the house enables its highest part to be in the centre of the site and the lower eaves to be nearer to the neighbouring gardens, said the practice.The building line is also pulled in from the rear boundary of the existing Ambleside housing. As the house is only a single-storey dwelling, there is no potential to overlook existing homes or their amenity spaces.
