Structural Calculations for Swanage Extensions
Every extension and load-bearing wall removal needs structural calculations signed off by a qualified engineer. In Swanage, where extensions to capture sea views, bungalow conversions, and sensitive alterations to Purbeck stone cottages, getting the steelwork right is the difference between a smooth build and expensive on-site changes.
What structural calculations cover
Beam sizing for load-bearing wall removals, padstone specifications, foundation design, lintel calculations for new openings, and roof structure modifications. Everything your builder and building control inspector need to approve the structural work.
Common structural work in Swanage
Swanage has Victorian seafront properties, 1930s bungalows with views, modern estates inland, and stone cottages in the Purbeck villages. Common projects include extensions to capture sea views, bungalow conversions, and sensitive alterations to Purbeck stone cottages. Each property type has different structural characteristics — a Victorian terrace with solid brick walls behaves differently to a 1970s cavity-wall detached house.
Building control compliance
Dorset Council building control will need to see approved structural calculations before work begins on any load-bearing element. Our engineer-certified calculations satisfy this requirement and are accepted by all approved inspectors.
