Structural calculations for loft conversions and extensions

I prepare structural calculations and drawings for loft conversions, rear extensions and chimney breast removals across south London. Building control needs these before work starts, and a clear package keeps your builder on schedule. Scope: - Site visit and measurement - Beam and lintel calculations (steel and timber) - Padstone and foundation checks - Drawings and calcs ready for building control Usually delivered within a week of the visit.
