DSB Property Designs prepares loft conversion plans for homeowners across Southend and Essex. We handle the measured survey, the planning drawings where needed and the building regulations drawings, so your builder has everything required to start.
A loft conversion adds a bedroom, home office or en-suite without taking garden space or moving house. Many can go ahead under permitted development, and we’ll check what applies to your property before we draw anything up.
Based in Westcliff-on-Sea, we’ve been preparing loft conversion plans across Southend and Essex for 22 years.
