A double storey extension in Dursley is perfect for families looking to remain in their current home while gaining much-needed space.

Homeowners can transform their living experience with a double storey extension that provides space for a dedicated office, guest suite, or an enhanced living area. This option prevents the frustration of compromising on your home's layout. With us managing every aspect- from structural groundwork to final touches- we ensure a smooth project experience that meets your vision.


Good ground preparation prevents delays. When planning a double storey extension in Dursley, we inspect soil stability, garden boundary walls, and buried drainage channels before the excavators roll into your rear yard. Heavy equipment needs a clear path across your driveway to reach the footings, so garden sheds, fences, and outdoor taps must be cleared away beforehand to avoid costly accidental punctures during heavy digger movements.
Dust travels through gaps. Because the work opens two full floors of your house, plastic screening along upstairs landing thresholds keeps bedroom carpets clean from airborne plaster powder and masonry silt. Kitchen utilities might need temporary isolation while the main pipe feeds get diverted around the new load-bearing footprint. That means sorting a temporary brew station in the dining room with an electric kettle and a small camping hob to keep your morning routine functioning properly while internal joists are notched.
By opting for a double storey extension in Dursley, you create significant additional square footage, yielding better functional benefits compared to single-level builds. This upward and outward expansion changes daily living in practical ways.
A well-executed double storey extension notably boosts a property's market value, making it a smart improvement choice. The extra bedrooms and amenities appeal directly to potential sellers and valuers.
Every double storey extension in Dursley is designed to harmonize with the existing home, matching brickwork, roof design, and window details. The final result appears as an intentional part of the original building, crafted to last.
Families requiring more space can enjoy a double storey extension without the hassle and expense of moving. This adaptivity means your home grows alongside you and fits your timeline.
We manage all trades and stages of your project under one roof, from groundwork to final finishes for your double storey extension. This eliminates any confusion and ensures consistent quality throughout the work.
Whether you need an open-plan kitchen or an extra bedroom above, a double storey extension allows flexible layouts crafted around your preferences, promoting both function and beauty.
Winter ground demands extra care. Trench digging during wet months means subsoil can turn to soup rapidly, making it vital to pump pooling rainwater out before pouring foundation footings. A double storey extension in Dursley often contends with heavy run-off coming off nearby fields, so we channel trench water straight into drainage gullies to protect the exposed clay banks from sudden collapse under wet mortar.
Exposed rafters require immediate protection. Once the top floor joists join the existing eaves, sudden rainstorms threaten ceilings below unless heavy waterproof sheeting stays lashed across the timber framework every evening. High winds require reinforced tarpaulins anchored with battens rather than simple loose weights that might slide down tiles into the driveway below. Keeping the upstairs bedrooms completely dry during timber installation avoids staining your existing downstairs plaster ceilings with dirty structural rainwater.

A double storey extension is an effective choice for upping your home's usable area without the complications of relocating. With space added to both levels, you'll enjoy a larger living area or kitchen downstairs, plus bedrooms or bathrooms upstairs. Such an extension serves as a valuable investment, making it worthwhile for years to come.
Each double storey extension we create integrates beautifully with the current home, using consistent brick and detail work. This seamless aesthetic appeals visually and in marketability, as future buyers are drawn to a well-designed addition. A thoughtfully executed double storey extension not only enhances the beauty but also the flow and character of your property.


Settlement happens in every structure. A double storey extension in Dursley joins brickwork of different ages, meaning the vertical expansion joint between the old house wall and the new masonry will compress as the heavy foundation settles into place. Inspecting the flexible mastic along this junction twice a year prevents small water drops from creeping behind the exterior render.
High gutters fill up fast. Fallen leaves from neighbouring gardens gather where the new pitched roof meets the existing main valley gutter. Blocked upper channels dump sheets of overflowing rain down newly pointed exterior walls, which soon causes green moss patches to spread across the dry foundation level.
Upper windows take brutal winds. Strong gusts push hard against exposed second-storey window gaskets, so lubricating the friction hinges every autumn keeps the sashes pulling tight against their rubber drafts. Without smooth closing catches, cold air seeps into the new bedrooms and increases the boiler load across the entire domestic heating loop.
A double storey extension deserves a tailored approach to ensure quality results. We view each project through the lens of craftsmanship, considering structural integrity and details throughout every phase. With two decades of experience under our belts, we specialize in enhancing homes across two levels, preserving the beauty of the existing structures. The result isn't just an addition-it's a harmonious blend with what was there before.

The main contractor handles settlement hairline cracks once the structure fully settles, usually after the building has experienced heating across a couple of seasons. It depends on whether the plaster shrinkage occurred naturally or if exterior moisture penetrated, because hairline lines in skimming just require simple filler touch-ups.
Rerouting uncharted underground sewage pipes or shifting buried electrical cables falls outside the main quotation, because hidden obstacles cannot be confirmed before soil excavation starts. If the digger strikes solid rock or unmapped soakaways, the extra machine hire and specialist waste removal get billed as distinct site variations.
Ask to see their Building control sign-off documentation from past jobs and inspect their recent Opinie na Facebooku. A capable firm will describe how heavy structural steels must be seated on proper concrete padstones rather than resting directly on bare breeze blocks, because double-height loads demand precise calculations.
Wet spells slow mortar setting on tall walls, but timber joists and roof trusses can still be installed between downpours. It depends on how securely the contractor wraps the work beneath tarpaulins, because protecting raw upper floor chipboard from pooling moisture prevents the floorboards from swelling and buckling later.
