The service
What it is and why it matters
A house extension adds new floor area to your home, usually at the back or side. It might be a larger open-plan kitchen, a family room, a downstairs bedroom or a utility and boot room.
Why professional help matters
An extension involves foundations, drainage, structure, roofing and a seamless tie-in to the existing house. When one team manages it, there are fewer gaps between trades, fewer delays and one person to call.
Who it's for
It suits households who need more ground-floor space than a garage or loft can give, and who have the garden room to build into.
When you need it
It's the right choice when the kitchen is too small for the family, when you need step-free living space, or when you love the area but the house no longer fits.
Getting it wrong
What happens when it's done badly
Extensions go wrong most often in the gaps between trades and in the join between old and new.
Leaks at the join
A poorly detailed connection between the new roof and the existing wall is the most common source of leaks in extensions.
Cracking and movement
Foundations that don't suit the ground, or a new wall not tied in properly, can cause cracks as the building settles.
Delays between trades
When nobody co-ordinates the builder, joiner, electrician and plasterer, each waits for the other and weeks are lost.
Cold or dark rooms
Too few windows or poor insulation leaves a new room that people avoid in winter.
Common mistakes we see
- -Choosing a builder on the lowest headline price, then paying for extras.
- -Not planning how the extension connects to the existing kitchen and heating.
- -Leaving decisions on windows, doors and finishes until the build is underway.
- -Starting work before the warrant and any planning permission are in place.
How we work
Our process, step by step
- 1
Visit and free quote
We look at the house, the garden and how you'll use the space, then give you a written quote with no hidden costs.
- 2
Drawings and permissions
If a building warrant is needed, getting it is the homeowner's responsibility. We'll tell you early what the drawings need to show so the work can start as soon as it's granted.
- 3
Groundworks and shell
Foundations, drainage, walls and roof go up, and the new shell is made watertight.
- 4
Knock-through and trades
We open into the existing house, fit any steels, and bring in our electrician, plumber and plasterer.
- 5
Finishing and handover
Floors, doors, skirtings and any fitted furniture are finished, then we walk round with you.
What you get

Pay for progress
No deposit. Once the job starts you pay at the end of each week for the work done that week, so you never pay ahead of progress you can see.
A join you can't see
We take care to match levels, finishes and lines so the extension looks like part of the house.
Clear quote
A written quote with no hidden costs, so you know where you stand before work starts.
Finished by joiners
Doors, skirtings, window boards and built-ins are fitted to a joiner's standard.
In detail
Types of extension we build
The right extension depends on your plot, your house and how you live.
Rear kitchen extensions
The most popular choice: a larger kitchen-diner opening onto the garden, often with bifold or sliding doors and roof windows.
Side extensions
Use the strip beside the house for a utility, boot room, downstairs WC or a wider kitchen.
Wraparound extensions
Combine side and rear to create a large open-plan space.
Flat vs pitched roofs
Flat roofs suit modern designs and roof lanterns; pitched roofs match the existing house and shed Scottish weather well.
Opening up internally
Most extensions involve removing an external wall and fitting a steel beam, the same kind of work we do in open-plan renovations.
Finishes
We can carry the extension through with matching flooring, panelling, a kitchen island or a media wall, so the room is ready to live in.

Questions
Frequently asked questions
How much does a house extension cost?
It depends on size, roof type, glazing and finishes. We give you a free written quote with no hidden costs after a visit.
How long does an extension take?
Typically a few months from groundworks to handover for a single-storey extension. Your quote includes a timeline.
Do I need planning permission and a building warrant?
A warrant is almost always needed, and some extensions also need planning permission. If a building warrant is needed, getting it is the homeowner's responsibility. We'll tell you early what the drawings need to show so the work can start as soon as it's granted.
Do you take a deposit?
No deposit. Once the job starts you pay at the end of each week for the work done that week, so you never pay ahead of progress you can see.
Can I live at home during the work?
Usually, yes. Most of the build happens outside; the knock-through is planned to keep disruption short.
Do you handle electrics, plumbing and plastering?
We co-ordinate our regular, trusted electrician, plumber and plasterer so you deal only with us.
Can you fit the kitchen too?
Yes. We fit kitchens and islands, so the extension can be handed over finished.
Which areas do you cover?
All of East Lothian, including Haddington, Tranent, Musselburgh, Prestonpans, North Berwick and Dunbar.
