We work with homeowners throughout Swindon to deliver practical, well-built extensions that complement their existing homes.
Two-Storey House Extensions Built Around Your Home
A double-storey extension can provide valuable additional living space on both the ground and first floors, making it an attractive option for growing families.
The layout and construction will depend on your property, architectural plans and the necessary planning and structural approvals.
Extra Bedrooms and Bathrooms
A two-storey extension can create space for additional bedrooms, an en-suite bathroom or a larger family bathroom.
This can be particularly useful for homeowners who need more accommodation but would prefer to remain in their existing property.
Larger Kitchens and Family Living Areas
The ground floor of a double-storey extension can provide space for a larger kitchen, dining room or open-plan family area.
Depending on the approved design, structural alterations may also help connect the new extension with existing rooms.
Side and Rear Double-Storey Extensions
We undertake double-storey extension projects to the side or rear of suitable properties.
Whether the proposed extension is possible will depend on the available space, planning requirements, neighbouring properties and the structural design.
Our Complete Double-Storey Extension Building Service
We provide a comprehensive construction service, coordinating the building work from the initial groundwork stages through to completion of the agreed building specification.
Groundworks and Structural Foundations
We undertake excavation, foundation construction, drainage works and associated groundworks in accordance with the approved plans and structural requirements.
Where additional structural engineering input is required, we can help arrange this, with professional fees charged separately.
Brickwork and Structural Construction
Our building work includes cavity wall construction, brickwork, blockwork, structural openings and associated masonry works.
We aim to ensure the new extension complements the existing property, including matching external materials where practical and specified.
First-Floor Construction and Roofing
Double-storey extensions require carefully constructed floor structures, supporting walls and roof systems.
We undertake the relevant building work in accordance with the approved drawings and structural specifications, including pitched roof construction and associated roofing works.
Structural Steelwork and Load-Bearing Wall Removal
Some double-storey extensions involve removing existing external or internal load-bearing walls to create larger connected living spaces.
Where required, we can arrange structural engineers and coordinate the installation of steel beams in accordance with their calculations.
The final steelwork specification and cost will depend on the structural engineer's design and any additional support requirements.
Plumbing, Electrics and Internal Finishing
Our building service can include plumbing, electrical installation, insulation, plasterboarding and plastering as required by the agreed project specification.
Painting and decorating, flooring and tiling are excluded from our standard quotations, although we can recommend trusted tradespeople for these finishing services.
Landscaping and external garden reinstatement are also excluded as standard unless separately agreed.
Building Your Double-Storey Extension From Architectural Plans
Many of our customers contact us once they already have architectural drawings prepared for their proposed extension.
We can review these plans, discuss the construction requirements and prepare a detailed quotation based on the agreed scope of work.
Where necessary, we can coordinate with structural engineers and Building Control to help ensure the construction follows the relevant approved designs.
Council charges, application fees and independent professional fees are payable separately by the customer.
If you're still at the early planning stage, we can also discuss our separate design-and-build service.
