Roof extensions: planning and advice
An additional floor requires an assessment of what the existing home can support.
Where should you start?A roof extension adds both space and load. Foundations, load-bearing walls, stairs, neighbouring connections and lifting access influence the design. Compare prefabricated and site-built options with the same scope.
Prepare for the discussion
Collect existing drawings and discuss structural design, access and permissions before agreeing execution.
