Residential construction
Home extensions across Glasgow and the West of Scotland.
Drawing-led extension delivery covering the new structure, its connection to the existing home and the finishes needed for a complete result.
What to expect
A coordinated construction package.
Single-storey, wraparound and larger residential extensions can involve considerably more than the visible new room. Ground conditions, drainage, structural openings, glazing, existing services and access all influence scope, cost and programme.
dB Construction acts as the main contractor, coordinating the agreed trades, procurement, temporary works and day-to-day delivery.
A typical scope may include
- Pre-construction review, programme and procurement coordination
- Site establishment, protection, welfare, access and waste arrangements
- Excavation, foundations, drainage and insulated floor construction
- Structural walls, steelwork and openings into the existing house
- Pitched or flat roofing, rooflights, flashings and rainwater goods
- Windows, external doors, insulation and weatherproofing
- Electrical, plumbing, heating and ventilation work
- Plastering, joinery, flooring, decoration and agreed external making good
What we need from you
- Property address and best contact details
- Existing and proposed architectural drawings
- Structural Engineer’s drawings and calculations, where available
- Planning Permission and Building Warrant status
- Kitchen, glazing and finish specifications, if selected
- Photographs of the property, garden and access route
- Target budget and preferred construction period
- Details of occupancy, parking, neighbour or access constraints
Before you enquire
Planning your project
What affects the cost of a house extension?
The size and specification are only part of the price. Foundations, drainage diversions, structural openings, glazing, roof design and access for deliveries can all affect the construction package. Share your target budget early so the design and finishes can be reviewed against it.
How do you prepare an estimate or quotation?
Send your drawings, available structural information and intended finishes. An initial estimate helps establish budget suitability. A detailed quotation needs a defined scope and review of the property, including access, waste arrangements and work connecting the extension to the existing house. Assumptions, exclusions and allowances should be clear before work is agreed.
Can we stay at home during the work?
This depends on how the new construction connects to your existing rooms and services. We need to discuss household access, dust protection, kitchen and bathroom availability, and any periods when rooms cannot be used. Tell us about children, pets, home working and other occupancy needs when you enquire.
When can the programme be confirmed?
The construction sequence depends on the agreed design, site conditions and procurement. Bespoke glazing, steelwork and kitchen deliveries need to be coordinated with the build. Share your preferred dates and any fixed commitments so a realistic programme can be discussed before a start date is agreed.
For the next step, see our estimating and project process, or send your project details.
