The work was done well, efficiently and cleanly.
Clear costs, no surprises
Transforming your home with a wrap around extension in Corsham creates the most spacious open plan living area possible. This option allows for a unique blend of style and practicality.
Done right, no shortcuts.
A wrap around extension in Corsham is an ideal choice for families looking to expand their living space without leaving their beloved home. By merging a rear and side extension into a single L-shaped structure, it offers a generous, open-plan ground floor that significantly enhances daily life. We take care of every step in this process, ensuring everything feels cohesive instead of haphazard.
Homes with unconventional layouts or underutilized side areas are where a wrap around extension shines. Instead of settling for the constraints of a linear layout, this approach reconfigures the entire ground floor to better match how families truly live. With over two decades of structural expertise, we tackle even the most intricate existing designs with elegance.
For property owners and investors, a wrap around extension offers a highly effective way to increase both usable space and the market attractiveness of a residential property. The extensive spatial changes a wrap around extension in Corsham achieves are often unmatched by any other single-phase construction, making it a solid and evident investment. We handle all aspects of the project through one point of contact, ensuring efficient delivery and results that stand out.


Narrow passageways cause sudden headaches. We often find overgrown hedges, water butts or heavy cast iron drainpipes blocking the route from the driveway to the rear garden lawn. When our team undertakes a wrap around extension in Corsham, wheelbarrows and small excavators need unhindered passage back and forth across that boundary line every single morning. Shifting outdoor toys, patio furniture, and old timber sheds ahead of our arrival prevents accidental scratches to your garden walls. Loose garden ornaments break easily. Keep the path clear.
Dust travels everywhere during knock-throughs. Heavy polythene sheeting taped across kitchen door frames stops fine airborne powder from settling into your hallway carpets, soft sofa fabrics, and upstairs bedroom wardrobes. You should also pack away glass tumblers, ceramics, and wall-hung paintings because vibrations from our trench diggers travel through masonry. Vibrations rattle delicate items. Moving these things into temporary plastic crates protects them against drops while the wrap around extension takes shape outside your current ground floor walls.
A wrap around extension in Corsham merges a rear and side structure into one L-shaped build, achieving the largest possible open plan space at ground level. This method offers an unrivaled spatial transformation.
Since a wrap around extension is crafted as a single cohesive unit instead of various add-ons, the transition from existing to new spaces flows seamlessly. This creates an inviting interior that feels complete, rather than a patchwork alteration.
Extending across two sides allows light to flood in from multiple directions, eliminating the shadows often cast by single-direction extensions. The result is a brighter, more welcoming ground floor throughout the day.
A wrap around extension serves as one of the most beneficial investments for homeowners, with the extensive spatial reconfiguration leading to tangible increases in market value. Generous, well-designed open-plan spaces consistently attract buyers.
With us managing every project phase, from structural groundwork to final finishes, there's no division of duties among trades. One skilled contractor oversees everything, ensuring the project stays on track and meets the quality standards the investment deserves.
Clay soil behaves unpredictably during relentless autumn downpours. Freshly dug foundation trenches can fill up with deep muddy puddles overnight, forcing us to run submersible pumps before we pour any batch of concrete footing. Delivering a wrap around extension in Corsham means watching local weather warnings closely so that exposed ground stays firm and stable under heavy footing loads. Wet earth collapses fast. We shield exposed trenches with thick tarpaulins when dark clouds appear over neighbouring hedgerows.
Freezing conditions pause external brickwork. Mortar mixed with icy water loses bond strength quickly, so we suspend outer leaf block laying whenever overnight frost turns surface aggregates brittle. Instead, we use cold mornings to construct internal timber studding, run flexible conduits behind plasterboard, or fit ceiling joists under existing dry cover. Frost ruins damp cement. Postponing brick laying for a mild afternoon saves structural walls from crumbling away later.

We commence by visiting your property in Corsham, examining the layout, and supplying a clear initial quote based on your wrap around extension needs.
Our experts carry out accurate on-site measurements and analyze existing foundations, load-bearing structures, and drainage systems to determine the ideal setup for your wrap around extension.
We manage the architectural planning to ensure compliance with current building regulations and maintain your home's character, then finalize the project outline in a transparent contract.
As your sole contractor for every aspect, we handle groundwork, structural framing, RSJ installation if necessary, and all building services, ensuring all trades work together smoothly.
We perform all installation and finishing work to top standards, followed by a detailed final inspection and a clear settlement process to conclude the project with full transparency.
Leaves collect inside shallow roof valleys. When deciduous trees drop foliage directly over a wrap around extension in Corsham, hidden gully outlets choke rapidly, forcing rainwater backward underneath the roofing felt. Routine checks prevent nasty ceiling leaks. You can simply scoop damp muck from the zinc flashing using a small garden trowel.
Sliding doors require occasional wipe-downs. Grit gathering in bottom tracks damages neoprene seals, allowing drafty air into your open space. Washing bottom runners with soapy water preserves smooth gliding rollers for years. Silicone along external brickwork also needs inspection after bitter winters. Cracked sealant lets water seep behind fresh render, so scraping out dried bead lines and applying fresh exterior mastic keeps moisture completely out.

No, local authority application charges and structural engineer calculation fees fall outside our basic build estimate. The property owner settles these fees directly with council bodies because submitted drawings remain under the homeowner's personal name.
Unmapped sewer pipes, buried electrical cables, or sudden bouts of freezing rain halt progress on site. If hidden pipes emerge beneath old foundations, building control officers must inspect the ground, which temporarily delays concrete deliveries until revised layouts get written clearance.
Yes, building right against boundary lines or digging footings near an adjoining wall requires formal party wall notices. When neighbours raise boundary queries in Corsham, an independent surveyor might step in to log existing wall cracks before heavy digging commences.
We begin with site clearance, ground trenching, and concrete foundations before laying masonry walls up to wall-plate level. The timber roof structure follows with weatherproofing layers, leading into internal wall removals, plumbing runs, electrical first fix, and final building control sign-off.
