Sweet Homes buys and fits the agreed products and materials for every job. We do not fit items bought or supplied by customers. Please allow at least four weeks from your first enquiry before construction can start. We agree your dates and costs with you before work starts.
A few details to get started.
Brunon and his team were on time every day. The site was always left tidy overnight and Brunon was always happy to chat and explain what they were doing.
He turned up on time, was courteous and completed the work to a high standard on the day stated, at the price stated. Very happy customer, will hire him again.

Consider where old and new meet
What would extra space change for you: cooking together, sitting around the table or getting out to the garden? Your extension belongs in the plan for how you use the whole home.
If your house has older details you value, discuss them with your appointed designer where the new space joins it. Sweet Homes builds from the agreed design, with the construction organised around the home it joins.
Our guide to sequencing renovation work explains why the order matters when connecting old and new spaces.
Before assuming an external alteration is permitted, read planning permission for flats and houses.

The construction, organised
A clear plan, shared with you.
We plan the junctions with the existing house before the trades arrive: drainage, services, access and the point when the rooms connect. You receive a clear construction sequence and know which choices are needed next.
Design, engineering and permissions
You appoint the architect, structural engineer and approval professionals your project needs. They own the design, structural information and relevant applications. Sweet Homes is the construction contractor. A building warrant must be granted before work starts. Electrical and gas work within our scope is carried out and certified by the competent trades we appoint.

Including VAT
This is a broad guide, not a quotation or a price promise for any particular feature or design. The final price depends on the measured property, existing conditions, agreed scope and selected specification. A written quotation follows assessment of those details.
Read the cost guideHouse extension scope, timing and planning
What is included?
The written scope can include site protection, groundworks, drainage, structure, walls, roof, windows, doors, services, plastering, floors, decoration and fitted joinery where agreed. The approved design and structural information define the construction. We supply and fit the agreed work. We do not offer labour-only or fit-only work. Chosen product codes can be included in our supply quotation.
How is the programme agreed?
The programme follows the agreed drawings, approvals, scope and ordering. For all work, allow at least four weeks from your first enquiry for the call, survey, quotation, decision and preparation; this is not a promised start date. We agree the construction sequence for your property.
Can we stay at home?
Often the new shell can be built separately at first. The more disruptive stage comes when openings and essential services connect. We discuss living arrangements, clean zones and any temporary services before site work; specific arrangements belong in the contract.
What happens if the work changes?
We record the proposed work, cost and programme effect and obtain agreement before carrying out changed work. Concealed findings that affect the design are referred to your appointed professional. The contract sets out the process for your scope.
How do we start?
Send your enquiry by form or email. We arrange a follow-up call to talk through the project, then a site visit where useful. Any visit fee is agreed beforehand.
What happens at handover?
The project contract identifies the handover checks, snagging route, workmanship terms and aftercare for the agreed scope. Any trade certificates come from the subcontractors who carry out that work.
What is needed beyond a rough sketch?
A sketch does not resolve foundations, roof connections, structural work or hidden services. Pricing follows the measured information, specified scope and required site checks. Your appointed design and structural professionals establish the information needed for the proposal.
Which alternatives should we compare?
Depending on the property, a loft conversion or garage conversion may provide a different route to more usable space. For a protected property, read the listed-building renovation page before fixing the proposal.
What if we need work urgently?
We do not start construction within four weeks of the first enquiry. The call, property assessment where needed, quotation, your decision and preparation come first. The actual start and programme are agreed for your project. If you need urgent help, contact an emergency tradesperson.
An extension changes the house beside it
Plan the connection to the existing rooms alongside the new floor area. Removing a rear wall, moving a kitchen or changing a route through the house can affect more of the home than the extension footprint suggests. Include the finishes and service changes on both sides of the connection.
To compare extension types on the same scope, read house extension costs and scope.
Test the layout with furniture and ordinary daily movement. More floor area is not automatically a better arrangement if it leaves a dark middle room, an awkward passage or a kitchen that people need to cross to reach the garden.
Use the site constraints to shape the brief
Check the practical route for construction as well as the finished access to the garden. Materials, excavation and waste all have to pass through the available space. Identify what can be reached from outside and what would need to pass through the home.
Keep the proposed design, drainage information and existing-building information together. If one remains uncertain, record the assumption rather than hiding it in a finished-looking plan. This helps distinguish a design preference from a constraint that needs resolving.
Project responsibility
Who manages the work
Brunon oversees project programmes across Edinburgh and is typically available by phone or email. The staff assigned to your job handle the day-to-day site work independently within the agreed scope, with the responsible contact confirmed before work starts.
Fully insured: £2 million public and products liability and £10 million employers' liability.
Our Christmas offer
Dinner is on us.
Book your renovation with us by 15 December 2026 and, while the work is under way, your first £50 of dinner is on us.
A Christmas present that arrives when you need it most. Picture it. The kitchen is down to bare walls, the hall smells of fresh plaster, and nobody wants to cook. So don't. Get a table somewhere warm, order something you would never make at home, and let someone else do the washing up.
Book by 15 December 2026. Your works can start later.
About your dinner voucher
- You book by accepting your written quotation by 15 December 2026.
- Your works can start after that date. We plan every project at least four weeks ahead.
- We give you the voucher once your works have started.
- It is a £50 voucher you can use at any of a group of independent Edinburgh restaurants and bars, so you choose where.

Offer terms
- The promoter is Brunon Rogowski Ltd, trading as Sweet Homes, company number SC700883, registered office 15 Calton Road, Edinburgh, EH8 8DL.
- The offer is for customers who book a renovation project with us. You book when you accept our written quotation in writing by 11.59pm on 15 December 2026. The offer closes then and will not be extended.
- Your works can start after 15 December 2026. We agree the start date with you, and never start works within four weeks of your first enquiry. Where a building warrant is needed, works start only once it is granted.
- We give you one £50 dinner voucher per project, in person or by post, once your works have started on site.
- The voucher is an Edinburgh's Flavour gift voucher, which you can use at any of its partner restaurants and bars in Edinburgh.

If we cannot provide that voucher, we will give you another dinner voucher worth at least £50.
- There is no cash alternative and no discount in its place. Your right to the voucher cannot be passed to anyone else or moved to another project.
- If the project is cancelled before works start, for any reason, including within your 14-day cancellation period, no voucher is given. Once we have given you the voucher, we will not ask for it back.
- The voucher is a gift on top of your contract. It does not change your contract price, scope or timing, and the price is not raised to pay for it.
