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.

Decide what the space can support
An existing cellar may suggest a useful extra room, but its height, stairs and condition come before the finishes. The intended use and specialist findings need to be clear before the construction is defined.
Before choosing finishes below ground, read about investigating recurring damp.
When deciding how much garage space to retain, read our guide to planning a partial garage conversion.
If it is part of an older home, include the existing structure and any details you hope to retain in your design brief. Think about who would use the space and how it connects to everyday life upstairs.
Basement conversions · Edinburgh
An existing cellar or basement may have a useful next chapter. We help define the construction once the intended use and specialist findings are clear.
Existing basements and cellars only. We do not excavate new basements beneath buildings; suitable use follows feasibility and specialist assessment.
What customers say
Bruno and his amazing team completely refitted the basement of the Tailors shop which had been damaged by flooding. They put new wall surfaces in, painted them and installed lots of useful shelving. Their work was neat and of the highest standard. They were punctual, hard-working and always tidied up after themselves at the end of the day. We all said how nice it was to have them working in the shop, and none of us would hesitate to use their services again, either here at work, or in our own homes.
Very happy with this team, who repaired a set of New Town cellar doors. They arrived when they said they would, their work was high quality and both Bruno and Dennis a delight to work with. We will use them again, and recommend them to our friends and neighbours.

Small moments, thoughtfully considered
The construction, organised
A clear plan, shared with you.
We bring the defined construction work into a practical sequence, with access, services and finishes considered together. Investigation and specialist design come first, so the quotation can distinguish the work needed from optional improvements.
Design, engineering and permissions
You appoint the structural engineer, building surveyor and moisture or waterproofing specialists the property needs, alongside design and approval professionals. Their findings and defined design information establish the construction to price. Specialist design and guarantees remain with those specialists. Sweet Homes is the construction contractor; where the work needs a building warrant, the warrant must be granted before works start.
Planning the budget

From around £18,000+
Including VAT
A broad starting point, not a quotation or a price promise. Cost depends on the existing property, intended use, conditions and agreed scope. Feasibility work and specialist investigations may be needed before a meaningful construction quotation can be prepared.

What is included?
This service concerns an existing basement or cellar, not excavation of a completely new basement beneath a building. Suitable use depends on the space and specialist findings. Construction may include enabling works, defined structural work, drainage, ventilation, insulation, services and finishes. 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.
Could it become living space?
Storage areas, utility rooms and habitable rooms have different needs. Headroom, daylight, escape, ventilation, heating and moisture conditions need assessment before a use is promised. Not every basement can become habitable.
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.
Why must the moisture source be understood first?
The moisture assessment needs to consider the construction, outside ground conditions and drainage as well as what is visible indoors. In traditional fabric, an impermeable layer can trap moisture or move the problem elsewhere. Have the cause and proposed system assessed by the appropriate specialist before choosing a finish or waterproofing treatment.
What needs checking before choosing a basement layout?
Check the available floor-to-ceiling height, stairs, foundations and load-bearing walls before choosing a room layout. Ask your appointed structural engineer to assess the options before assuming that lowering the floor is practical. Ground conditions, drainage, required permissions and any title restrictions can change the proposal before finishes are selected.
Who checks title restrictions and permissions?
Ask your solicitor to check any title or ownership restrictions. Your appointed design and approval professionals establish the planning, listed-building and building-warrant route for the proposal. These are separate checks; Sweet Homes prices and carries out the agreed construction.
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.
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.
Early planning also means considering hidden renovation risks before committing to a scope.
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.
