We work with homeowners, self-builders and developers throughout both counties — bringing local knowledge of the planning authorities to every project.
Orange Key provides architectural design, planning drawings and building-regulation drawings across Berkshire, Oxfordshire and the surrounding areas — from house extensions and loft conversions to renovations and new homes. Because planning policy and building-control procedures vary slightly between local authorities, experience of the relevant systems is a real advantage when developing a proposal.
