Covering Dorchester
We work in Dorchester (DT1) and the places around it, including Weymouth, Bridport and Yeovil.
Homes in the South West
The South West mixes stone and render cottages, Victorian terraces in the larger towns and modern estates, and many historic centres are conservation areas where materials and roof shapes are closely controlled.
What goes into a structural alteration?
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
- Temporary works and propping
- Steel beam installation on padstones
How much should I budget for a structural alteration?
Indicative costs for structural alterations. London and the South East usually sit towards the top of each range.
| Structural alterations | Guide price incl. VAT |
|---|---|
| Single load-bearing wall removal with steel | £3,000 to £7,500 |
| Chimney breast removal with support | £1,800 to £4,500 |
| Multiple walls or full open-plan remodel | £8,000 to £20,000 |
Do you need permission for a structural alteration in Dorchester?
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it 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 can change the price or programme?
- 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.
What are the steps?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- 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.
