Covering Bonnyrigg
We work in Bonnyrigg (EH19) and the places around it, including Dalkeith, Musselburgh and Haddington.
Homes in the Lothians
Housing in Scotland includes tenements in the cities, sandstone villas, inter-war and post-war semis and a large number of bungalows, which often suit dormer and upward extensions.
What is an upward extension?
An upward extension adds a new storey on top of an existing house, most often turning a bungalow into a two-storey or chalet-style home. It can double the floor area without using any of the garden.
- Building warrant application and completion certificate
- Roof removal and temporary weather protection
- Full fit-out of the new rooms
How much should I budget for an upward extension?
Use these ranges to budget for bungalow and upward extensions; the survey turns them into a fixed price for the agreed specification.
| Bungalow and upward extensions | Guide price incl. VAT |
|---|---|
| Chalet conversion with dormers (total) | £45,000 to £85,000 |
| New first floor, standard specification | £2,200 to £2,800 per m² |
| New first floor, good specification | £2,800 to £3,300 per m² |
| New first floor, high specification | £3,300 to £3,800 per m² |
Planning and building rules in Bonnyrigg
Projects in Scotland need a building warrant from the council before any building work starts, and a completion certificate once it is finished. Planning permission is a separate decision. The Party Wall etc. Act does not apply in Scotland; shared walls are governed by title deeds and the law of the tenement where relevant.
Adding a storey in Scotland needs planning permission and a building warrant.
What can affect an upward extension?
- The staircase takes space from the ground floor plan.
- The house is exposed while the roof is off, so the sequence is planned tightly.
From first call to completion
- 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.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
What people ask before starting
Do we need to move out?
Often for part of the job, while the roof is off and the new floor is formed. We plan this with you.
How long does it take?
About 12 to 24 weeks on site.
