New Build Plot Opportunities in St Albans

Garden plot developments are the most common new build route in St Albans — subdividing a generous back or side garden to create a new building plot subject to planning permission from St Albans District Council. Replacement dwellings — demolishing post-war properties and building larger modern homes — are increasingly popular in Marshalswick, Oaklands and Chiswell Green where 1950s and 1960s properties sit on good-sized plots. Occasional infill plots between existing properties also come to market.
