Green Belt Replacement Homes & Dwellings
Green Belt replacement dwellings are an allowable exception under national and local green belt policy.
The NPPF states that “the replacement of a building, provided the new building is in the same use and not materially larger than the one it replaces”.
While there is no definitive legal definition of “materially larger” there have been many appeals and legal cases which try to ascertain what the term means and what scale should be allowable.
In addition, each Local Planning Authority will have their own definition of what they would consider “materially larger” when considering green belt replacement homes, but often these range from around 15 – 30% from the existing dwelling.
The policies for house extensions within the Green Belt have a key difference in that such calculations are based on the “original” house whereas green belt replacement homes calculations are based upon the “existing” size of the home.
The two different calculations can help to dictate or plan the strategy for a plot with an existing house.
Plande has a wide range of experience of green belt replacement dwellings and justifying “materially larger”. The following case-studies provide some interesting examples and are not necessarily an exhaustive list.
The brief for a green belt replacement dwelling is often to create a house either as large as possible or significantly more than either the existing house or that policies would allow. While this would normally not be acceptable we have obtained green belt replacement home planning permission for far in excess of what either policy or the LPA would normally allow.
The following case studies provide a small sample of green belt replacement homes we have been involved with.
Green Belt Replacement Dwelling in Macclesfield, Cheshire East
The detached dormer bungalow had previously been extended past the LPA’s suggested 30% local planning policy, however, our clients wanted a substantial green belt replacement dwelling although the LPA initially suggested allowing only an additional 10 – 15
Ultimately we achieved planning permission for a green belt replacement house over 250% larger than the “existing” dwelling, with further extensions creating over 300% larger. In

Replacement home in the Green Belt, Parbold
A green belt replacement home was sought by our clients to replace their existing dormer bungalow which sat in a row of identical dwellings on an elevated site. The proposals sought a contemporary two storey green belt replacement dwelling that reflected the context of the site and character of the area while creating a modern addition to the housing stock. The proposals were substantially higher than the existing dwelling but we persuaded the LPA that the overall design would not impact on the openness of the Green Belt.
