By expanding your home across two levels, a double storey extension in Kingswood effectively transforms your living space with precision and lasting impact.
Done right, no shortcuts.
A double storey extension in Kingswood is perfect for families that have outgrown their home but prefer not to relocate. This option provides valuable extra space on both levels, offering a spacious kitchen or living area downstairs and an additional bedroom or bathroom upstairs. Each double storey extension we design blends seamlessly with the existing structure, ensuring that brickwork, roof lines, and window details are matched with great care.
For property investors, a double storey extension in Kingswood serves as a smart strategy for boosting rental income and enhancing long-term value. By adding substantial square footage across two levels, investors can maximize property potential without the hassle and expense of moving, making it a savvy choice. Our company brings over 20 years of experience to guarantee that the finished product appeals to both discerning tenants and prospective buyers.
Homeowners looking to create a functional home office, a guest suite, or simply a more spacious living environment will find that a double storey extension fits the bill perfectly. Instead of settling for a smaller addition, this approach provides a far-reaching transformation of your property. With our team managing every step from groundwork to final touches, we ensure that the process is handled with accountability and clarity.


Excavators need clean paths. When starting a double storey extension in Kingswood, we frequently discover that narrow garden gates, timber sheds, or outdoor heat pumps block plant machinery from entering the rear yard safely. You will want to prune heavy branches, shift wheelie bins, and take down side fence panels so delivery trucks can drop trench materials without scraping your brickwork or damaging your neighbour's tarmac driveway. Clear pathways prevent delays.
Drains hide under grass. Buried clay sewer pipes, soakaways, or forgotten inspection chambers often sit right where heavy footings must go down to bear two stacked floors. Finding these early prevents raw effluent backing up into ground floor sinks while our diggers scrape the topsoil. You will avoid sudden halts if you locate your inspection lids before we break ground, showing where water lines exit your kitchen walls.
A double storey extension adds significant space on both levels, offering much greater room than a ground-level build for a similar investment. This upward and outward expansion changes how you experience your home every day.
A well-executed double storey extension can significantly boost your property's market value, making it one of the soundest investments a homeowner can undertake. The added bedrooms, bathrooms, and living areas are attractive not just to future buyers, but also to appraisers.
Every double storey extension we construct is designed to closely match the existing property in terms of brickwork, roof lines, and window details, so the outcome appears to be an original part of your home. The finish is made with intention, ensuring durability.
Families needing extra space can have everything they want without the hassle and expense of moving to a larger home. Your space can evolve around your needs, according to your timeline.
We handle every element and phase of the project in-house, from groundwork and structural work to the final finishing touches. This approach minimizes the issues that arise from juggling multiple contractors and guarantees consistent quality from start to finish.
Whether your priority is a more spacious kitchen and open-plan living space, or an extra bedroom with an en-suite, the layout is designed exclusively around your vision. This results in a home that functions with purpose and elegance at every level.
A double storey extension presents considerable structural demands that many clients may overlook until the work is underway. Requirements such as foundation reinforcement or the installation of steel beams must be met with both proper engineering insight and practical know-how. Our company evaluates all these needs from the start, ensuring that every structural choice aims for long-term stability. A double storey extension completed to these standards becomes an integral, enduring element of your home.
Clients often find juggling multiple trades frustrating, especially with a project of this magnitude, where delays in one area can lead to setbacks in others. A double storey extension involves various tasks such as groundwork, framing, roofing, plumbing, and electrical work, and all of them need to be carefully scheduled. We take the lead as your single point of accountability, managing every aspect of the project seamlessly to ensure timely completion built to your expectations.

We connect with you to understand your project's full scope, assess site conditions, and offer a clear initial estimate based on your specific needs.
Our architects will create detailed drawings tailored to your double storey extension, and handle the planning permissions and building regulation submissions on your behalf.
Once approvals are obtained, we finalize the contract with a transparent breakdown of costs and a clear project timeline, ensuring every stage of your double storey extension is defined before construction begins.
We conduct all groundwork, foundation preparations, brickwork, framing, and roofing, making certain that the new extension blends smoothly with the existing property in both structure and appearance.
We oversee all building services including plumbing, electrical work, heating, and ventilation, finishing with complete interior work, and a final inspection and formal handover of your property.
Frost ruins fresh mortar joints. During colder winter months, wet mortar can freeze inside masonry pores, weakening external walls that need to carry heavy upper floor joists and roof trusses safely. We shield freshly laid bricks with insulated sheets to prevent surface crumbling before mortar cures fully.
Heavy rain floods trenches fast. When erecting a double storey extension in Kingswood during summer downpours, uncovered subfloors risk soaking existing floorboards through temporary wall openings. We bolt heavy tarpaulins tight across exposed joists so downpours run into garden gutters instead of your carpeted rooms.


High gutters catch autumn leaves. Roof junctions where an extension meets old masonry collect twigs that quickly choke downpipes, causing rainwater to spill behind fascias into upstairs bedrooms. You need a sturdy ladder to scoop rotting foliage out from deep zinc channels before heavy winter storms hit.
Wind drives rain sideways. Strong southwesterly gales beat against upper bedroom glass, meaning cracked silicone seals will let damp seep directly into internal plasterboard sheets over time. Inspecting external mastic beads every few years stops subtle moisture stains from spreading down your newly decorated lounge walls below.
Fresh plaster settles naturally. New structural blockwork settles under the weight of a double storey extension in Kingswood, creating hairline cracks along internal corners where old walls touch new framework. Applying flexible filler before repainting keeps these junction lines neat as central heating dries timber joists throughout the initial winter.
A double storey extension is one of the most thoughtful decisions a homeowner can make and requires a similarly thoughtful delivery approach. We treat every double storey extension with precision in scheduling, material selection, and attention to detail from the beginning. With over 20 years in residential projects, we smooth out the process of expanding your home across two levels without losing any of its original character, creating an addition that feels genuinely part of your property instead of an afterthought.
From the first estimate to project completion, your double storey extension is completely managed in-house. We organize every trade’s participation, from the groundwork and structural framing to roofing, plumbing, and interior finishes, ensuring a seamless transition from one phase to the next. Such a significant extension requires precise scheduling and clear communication, which is why our process prioritizes these elements. You deal with only one point of contact-ensuring every decision reflects the whole project perfectly.

Each project by our Construction Company leaves clients with refined spaces, enduring quality, and elevated comfort.
Mucha Construction Ltd delivers Construction Company services within a precise 20-mile radius of Bristol.
Everything starts with ground investigation, followed by laying deep foundations and building up masonry walls. Once roof rafters are fully tiled and waterproof, carpenters erect internal stud partitions before plumbers run pipes and inspectors verify structural stability.
You need party wall notices signed whenever new foundations are dug close to boundary fences or shared walls. Local council planning notices and formal building regulation sign-off documents must also be in place before breaking external brickwork.
Provide full architectural sketches, structural engineer calculations, and clear photos of current electrical fuse boards or boiler setups. Knowing where underground manholes sit in Kingswood helps calculate foundation depths correctly from the beginning.
People often choose cheap boilers that cannot generate enough water pressure for an extra upstairs bathroom. Overlooking existing plumbing capacity means poor shower flow and expensive heating modifications after wall plastering finishes.
