What is a new build home?
A new build home is a house built from the ground up on a cleared plot, a garden plot or a replacement-dwelling site. We work with plot owners and self-builders to design, gain approvals and build the house, either to a fixed design or from initial ideas.

Do you need planning permission for a new build home in Orpington?
Approvals for a new build home in Orpington follow the rules for England. In England a new home needs full planning permission (or permission in principle followed by technical details consent). Councils assess design, access, neighbours and drainage, and the Community Infrastructure Levy may apply, though self-builders can claim an exemption before starting.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
