Expand your living space thoughtfully with a single storey extension in Trowbridge designed and delivered by us.
Done right, no shortcuts.
A single storey extension is perfect for families in Trowbridge who have outgrown their current space but want to stay put. Whether you're looking for a bigger kitchen, an open-plan dining space, or a cozy living area, adding a single storey extension brings welcome square footage without affecting the upper levels. We have been assisting families in transforming their homes for over twenty years, overseeing each stage of the build under one roof. The result? A thoughtful, well-integrated addition that feels like it was always part of your home.
For homeowners in Trowbridge focused on long-term property value, a single storey extension ranks among the most prudent and rewarding investments. Rear and side extensions are consistently identified as high-return improvements in the UK housing market, and a single storey extension finished to a high standard increases that return even further. Each project is approached with meticulous precision and accountability, from the first estimate to the final handover. The process is clear and transparent, and the quality shines through in the final result.
A single storey extension can significantly boost the lettable area and rental yield of an investment property in Trowbridge, making it an appealing option for landlords managing portfolios or developing HMO schemes. Often, a single storey extension completed under permitted development allows for quicker implementation without the delays of lengthy planning processes. We are equipped to coordinate these projects expertly, managing all trades and compliance needs through a single contact. For investors prioritizing reliability, our approach promises a measurable impact.


Access routes must stay clear. When planning a single storey extension in Trowbridge, we verify boundary markers, side alleys, and side gates before bringing a mini digger past the rear fence panels. Narrow passages often dictate whether spoil travels out in skips or wheelbarrows. A clipped hedge makes an enormous difference to morning unloading. You should protect flagstones and pack away garden planters.
Unexpected pipework brings headaches. We examine where your private gullies join public sewers, checking inspection chambers with pry bars before footings are dug into clay soil. An unmapped soakaway or an old cast-iron soil pipe can force an alteration to the depth of the new concrete trench. Relocating an outside tap or an external power socket early prevents awkward delays.
A single storey extension is one of the best ways to achieve a truly usable room, whether that's a larger kitchen, an open-plan dining area, or a dedicated living space tailored to your lifestyle in Trowbridge.
Depending on the size and type of your property, many single storey extensions can be constructed under permitted development rights, which lessens the time and complexity associated with full planning applications.
Extending your home adds valuable square footage, which translates directly into a stronger market position, making it one of the most financially sound upgrades a homeowner can undertake in Trowbridge.
Unlike multi-level constructions, this type of project requires less disruption to the existing structure, leading to shorter timeframes, a more contained build process, and significantly less disturbance to your everyday life.
With our team overseeing every aspect from groundworks and structural elements to installations and finishing touches, there’s no need for you to manage multiple contractors, ensuring consistent quality and clear responsibility throughout.
Each extension we build is planned with close attention to how it connects with the existing property, ensuring the addition feels cohesive, thoughtfully designed, and built to last.
Mortar dust migrates everywhere. We tape heavy polythene membranes right over internal doorways and seal warm-air floor grates long before knocking through an external cavity wall with sledgehammers. Dust clings to soft furnishings in adjacent rooms, so isolating the hall or dining room preserves your carpets from grit and abrasive tracking. The knock-through stays closed until the new outer envelope is completely watertight and dry. We fit temporary zip doors for inspections.
Daily life carries on. When a single storey extension in Trowbridge involves taking down the old kitchen wall, we can set up temporary sink connections or hot plates in a utility space so you are never left without basic cooking facilities. Washing machines might move temporarily into a garage, while pets need a secure spot away from open garden boundaries during foundation pouring. Noise levels drop significantly once structural timber rafters and external brick layers are fully secured in position.

We meet with you to discuss your single storey extension in Trowbridge, assess the site conditions, and provide a clear preliminary estimate tailored to your property.
Our team performs detailed on-site measurements to accurately capture every dimension before the contract is finalized, ensuring that both parties have a clear agreement moving forward.
We oversee all excavation, foundation work, and structural framing with the precision your single storey extension deserves, managing each trade under one roof from day one.
Once the structure is established, we install roofing and weatherproofing systems, then proceed with all building services like plumbing, electrics, and heating, conducted by our qualified professionals.
We complete all internal finishes to the standard your single storey extension requires and conduct a comprehensive quality review before handing over the newly completed space on time and aligned with the agreed specifications.
A single storey extension effectively reclaims space that your household has outgrown. Whether you’re envisioning a spacious open-plan kitchen, a designated dining area, or a cozy living room that connects with your garden, the final product is a home operating with far greater fluidity. A well-executed single storey extension adds not just square footage, but a quality of life that can be instantly appreciated. For over twenty years, we have transformed spaces for clients, and the difference is always clear.
In addition to the comfort it adds, a single storey extension embodies a solid investment in your property’s future value. Buyers and appraisers recognize well-integrated extensions as valuable enhancements to market desirability. When executed with architectural awareness and built to high standards, a single storey extension becomes a true asset rather than just another modification. Our commitment ensures that each project is achieved to that level, from precision in groundworks to excellence in finishing.


Standing water causes trouble. Autumn brings rotting leaves from nearby sycamores directly into the parapet outlets, blocking rainwater flow from flat roofing membranes. We explain how clearing roof valleys and unclogging rainwater downpipes twice a year protects the timber fascia boards from premature rot. A quick glance up at the drainage hopper after a heavy storm tells you everything you need to know.
Materials react to weather. During dry summers and freezing winters, structural timber joints and plasterboard linings expand and contract at noticeably different rates, creating hairline cracks along internal ceiling corners. For any single storey extension in Trowbridge, applying flexible decorators caulk rather than rigid filler along these joints keeps the painted finish intact through seasonal temperature swings. It is normal movement.
Air circulation matters immensely. Furnishing an enlarged open-plan zone with massive rugs over heated screed floors traps heat and reduces heating efficiency across the whole space. We urge homeowners to leave small gaps behind deep storage cupboards placed against external insulated walls, preventing stagnant cold spots and hidden condensation during damp winter months. Good airflow keeps corners dry.
Every single storey extension starts with a discussion, and that’s precisely what we encourage you to engage in. Over the years, we have shepherded homeowners through all stages of the process, from initial estimate to final handover, ensuring clarity and precision at each step. Having your single storey extension executed by a single contractor avoids fragmented communication and unexpected issues along the journey.
Reaching out to us means we carefully learn about your property, your aspirations, and the essential requirements that will inform your single storey extension project. Comprehensive site assessments and detailed measurements are conducted before a single brick is laid, guaranteeing structural integrity and design coherence are integrated from the very beginning. With our team managing all aspects-from groundwork to installation and finishing-the end result reflects both quality craftsmanship and thoughtful design.

Ground conditions and structural steel sizes drive costs up or down. If your property sits on unstable clay, foundations must go much deeper than standard trenches. Knocking out a main load-bearing back wall requires heavy steel beams, whereas smaller openings need far less structural reinforcement and simpler labour.
Decorating, specialist floor coverings, and kitchen units are normally priced separately because personal choices vary so widely. Moving an external gas meter, rerouting shared mains drainage, or upgrading an old consumer unit in Trowbridge will also sit outside a standard build contract unless specifically agreed beforehand.
We walk through the finished build together, checking window seals, door latches, and plaster joints before issuing your Building control sign-off documentation. Minor settling cracks or sticking timber doors that appear after the heating runs for a few weeks are adjusted during a return visit once materials settle.
Excavating near a shared boundary wall or building directly on a dividing line requires written notices to your neighbours. If they raise objections or have concerns about their own footings, a surveyor must inspect both properties beforehand to record condition and establish working hours before ground breaks.
