Two Storey Extensions

Two storey extensions, or any extension at or above first floor level, should be set at least one metre from the flank boundary of the site (see figure 1 ). A gap will ensure that a terracing effect is not produced and the spacious character of the area is maintained. The second reason for a 1m gap is to ensure that an extension will not have an over dominant effect on an adjacent property. In some cases, for example in Residential Areas of Exceptional Character (see policy H10 of the South Bucks District Local Plan), even greater gaps to the boundary may be required. If the extension is located adjacent to an area of open land, including for example a field, or a public highway which is likely to remain permanently open, this requirement could be waived.



Figure 1 the one metre rule

Where the original building has a pitched roof, two storey extensions should be constructed with a pitched roof. The angle of the roof should be the same as, or close to the angle of the existing roof. Flat roofs for two storey extensions will usually be unacceptable (see figure 2).
