Rear extension & internal refurbishment (alterations)
- Design of new joists for flat roof extension, with timber trimmers for roof-lights
- Flitch beam design for large span roof-lights. Eco design thus reduced steel.
- Steel lintel with bottom plate for rear opening bearing onto steel columns either side (Steel Frame design)
- Steel Box Frame design for lateral stability of rear extension
- Sway stability check for Steel Frames
- Strip foundation design with beam & block floor span
- New cavity wall design for rear extension walls
All design was finally checked and drafted on AutoCAD. Structural details and sections all provided.
