Structural Engineering for Greenwich Loft Conversions

We specialise in the structural design of loft conversions for properties across Greenwich, from Victorian terraces in Westcombe Park to semi-detached homes in Plumstead. Our engineers provide efficient designs to maximise headroom and floor space, ensuring your new loft is safe, compliant, and comfortable. We deliver all the necessary structural information for your builder and for Building Control approval with Greenwich Council.

Local Challenges

Loft Conversions in Greenwich

The primary challenge in Greenwich's older housing stock is often the condition of existing roof timbers and the need to strengthen floor joists to support a new habitable room. In conservation areas like Blackheath Park, the external appearance of a dormer is strictly controlled, which influences the internal structural design. We navigate these constraints by designing efficient steel ridge beams and floor structures that work within the permitted development or planning-approved envelope.

  • Steel ridge beam and floor support calculations
  • New floor joist sizes and specifications
