House Extension Services
Single-Storey & Rear Extensions
Extend a kitchen, dining room or living area with a practical single-storey extension. We undertake the associated groundworks, structural building work, roof construction and carpentry, with the specification developed around your drawings and property.
Double-Storey Extensions
Where the design, structure and approvals allow, a two-storey extension can add living space downstairs and bedrooms or bathrooms upstairs. Careful planning is needed for foundations, floor structure, roof connections and integration with the existing house.
Kitchen Extensions & Open-Plan Living
Kitchen extensions often combine new floor area with changes to existing walls and openings. We can coordinate structural alterations, steel beams, new openings, roofing and the building work required before kitchen fitting and finishes.
Structural Alterations, Roofing & Joinery
Our carpentry and building background covers timber floors, traditional and flat roof construction, structural openings, first-fix and second-fix joinery. Structural steelwork and other specialist trades are coordinated to suit the approved design.
What's Involved in Building a House Extension?
Every property is different, but understanding the typical construction sequence helps you plan the work, budget and decisions ahead.
1. Site Review, Drawings & Quotation
We review access, existing levels, drainage, the proposed layout and available architectural or structural information. Clear drawings and a defined specification allow a more accurate quotation and help identify decisions needed before work starts.
2. Groundworks, Foundations & Drainage
The early stages can include setting out, excavation, foundations, below-ground drainage and preparation for the floor build-up. Foundation details and drainage arrangements depend on ground conditions, the design and the relevant approvals.
3. Walls, Openings & Structural Steelwork
Brickwork or blockwork forms the extension shell. Where new openings connect the extension to the house, suitable temporary support and installation of structural steelwork follow the engineer's design and construction sequence.
4. Roof, Insulation & Internal Works
Once the structure is ready, work moves to the roof, weatherproofing, windows and doors, insulation and the internal stages. Carpentry, services, plastering and finishes are planned around the agreed scope and specialist trades.

Managing Your Extension Project
Building an extension means coordinating groundworks, brickwork, structural steelwork, roofing, glazing and internal trades in the right order. We focus on practical sequencing, clear communication and the detail needed to connect new construction to the existing property.
We can discuss the scope from your initial ideas, or review architectural drawings and structural calculations where these are already available. The final quotation and programme depend on the design, access, specification and lead times.

House Extension FAQs
Do I need planning permission for a house extension?
Some extensions may qualify as permitted development, while others need planning permission. The answer depends on the property, its location and the proposed size and design. We recommend checking the position with the local planning authority before committing to the build.
Do extensions need Building Regulations approval?
Most habitable house extensions need to comply with Building Regulations, even where planning permission is not required. Structural design, insulation, drainage and other details should be addressed through the appropriate approval and inspection process.
How much does a house extension cost?
Costs vary with the floor area, ground conditions, structural steelwork, roof type, glazing, access and level of internal finish. Architectural drawings and a clear specification help us prepare a quotation that reflects the actual work rather than a misleading one-size-fits-all figure.
Can you build single and double-storey extensions?
Yes. We undertake both types of residential extension, subject to the property's suitability, the design and the necessary approvals.
Can you remove an external wall to make an open-plan kitchen?
We undertake structural alterations and can coordinate steelwork where required. Openings must be designed and supported appropriately, using structural calculations and an agreed construction sequence.
What do you need to provide a quotation?
Send us your location, a short description of the extension, any drawings or structural details you have and your preferred timescale. If plans are not yet available, we can discuss what information will be needed to price the project accurately.
