Covering St Albans
We work in St Albans (AL1, AL3) and the places around it, including Harpenden, Hatfield and Hemel Hempstead.
Homes in the East of England
Across the East of England, newer estates often have integral garages and room for rear extensions, while older towns have Victorian terraces and conservation areas that shape what can be built.
What does a structural alteration involve?
We arrange the structural calculations, support the floors and roof above with temporary props while the wall comes out, install the steel on padstones, then encase it for fire protection and make good. Chimney breast removals and new openings in external walls follow the same process.
- Structural engineer’s design and calculations
- Steel beam installation on padstones
- Making good floors, walls and ceilings
How much does a structural alteration cost in St Albans?
Typical ranges for structural alterations. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.

Planning and building rules in St Albans
Projects in England go through two separate checks. Planning (or confirmation that the work is permitted development) comes from the district, borough or unitary council, and building regulations approval comes from the council’s building control team or a registered building control approver. Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.
Internal work like this does not usually need planning permission unless the house is listed or your permitted development rights have been removed. It does need building regulations approval because it affects the structure.
What should St Albans homeowners check first?
- Shared chimney breasts and walls can involve the Party Wall Act.
- The beam size can mean a downstand in the ceiling unless it is set flush within the floor.
From first call to completion
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Survey at your house. We look at the existing structure, services and access, and agree what the design needs to achieve.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Structural alterations: common questions
How do I know if a wall is load-bearing?
We check on site and confirm with the structural engineer.
Can the steel be hidden in the ceiling?
Often it can be set within the floor depth, avoiding a downstand. The engineer confirms what is possible.
