Can You Do a Loft Conversion on a New Build Property?
Yes — but new build loft conversions require specialist expertise.
Many new build homes in London are sold with planning restrictions or permitted development limitations. In some cases, permitted development rights may have been removed by the developer or local authority.
Key considerations include:
Planning permission restrictions (especially within the first 10 years)
Structural load capacity of roof trusses
Head height requirements (minimum 2.2m ideal)
Building regulations compliance
Party wall agreements (if semi-detached or terraced)
Our team assesses your property carefully to determine whether your new build loft conversion in London can proceed under permitted development or requires full planning permission.
