Clear costs, no surprises
We create double storey extensions that significantly enhance your home, transforming spaces with commitment and attention to detail for clients in Clevedon.
Done right, no shortcuts.
A double storey extension in Clevedon is perfect for families that feel cramped in their current home yet wish to stay put. This type of project adds meaningful space to both levels, allowing for a larger kitchen or living area downstairs and an extra bedroom or bathroom upstairs. We meticulously design and construct each double storey extension to align with the existing architecture, ensuring that matching brickwork, rooflines, and window details are expertly handled.
For property investors, a double storey extension in Clevedon serves as an efficient avenue to enhance rental income and increase asset value. Expanding vertically provides significant extra square footage without the upheaval and expenses of relocating, marking it as a wise investment. We bring over 20 years of expertise to ensure that the final outcome aligns with the expectations of discerning tenants and prospective buyers.
A double storey extension is ideal for homeowners looking to establish a dedicated office space, create a guest suite, or simply enhance their living area. Instead of adjusting layouts or compromising with a single-level addition, this option greatly elevates the home’s function. With us overseeing all steps-from laying foundations to final touches-the entirety of the project is managed cohesively, providing assurance and clarity.


Diggers need clear passage. Bringing heavy machinery into your rear garden for a double storey extension in Clevedon requires removing garden gates, moving decorative pots, and temporarily trimming overgrown boundary hedges. When a narrow path between two homes gets blocked by a timber shed, our team has to pause work while the timber frame is dismantled so earth-moving gear can roll through without scraping brickwork. Ground protection mats spread the weight over your lawn turf. That avoids deep ruts.
Hidden pipes alter trench routes. Groundworkers scan the soil with locators because older private drain connections or forgotten soakaways often sit right where new footings must go down. We trace each clay pipe back towards an inspection chamber, lifting iron lids across your driveway to verify actual fall and water flow directions before digging starts. Striking an unmapped electricity cable under a garden patio halts excavation immediately and calls for specialist utility repairs. Mark every garden tap beforehand.
A double storey extension provides impressive square footage across both levels simultaneously, yielding far greater spatial benefits than a single-level extension for a similar investment. By expanding both upwards and outwards in one seamless project, we redefine home functionality day by day.
An expertly crafted double storey extension significantly raises a property’s market value, making it one of the most financially savvy improvements a homeowner can pursue. The new bedrooms, bathrooms, and living spaces directly appeal to future buyers and valuers alike.
Every double storey extension we create is carefully designed to complement the existing property in terms of brickwork, rooflines, and window designs, ensuring it appears as an integral part of the original home. The finish is meticulous and built to last.
Families and those needing extra space can receive all they desire without the cost and chaos of moving to a larger home. The residence evolves harmoniously around its inhabitants, adapting to their needs and timelines.
We manage every trade and phase of the project under one roof-from groundwork and structural work to final touches. This approach minimizes fragmentation common with multiple contractors, ensuring consistent quality from inception to completion.
Whether your main focus is a more expansive kitchen and open-plan living space below or an additional bedroom and en-suite upstairs, we tailor the layout around your unique requirements. The result is a home designed to function effectively at every level.
Launching a double storey extension introduces significant structural demands that clients often overlook until construction is already in progress. Reinforced foundations, RSJ placements, and the meticulous integration of new brickwork into existing structures require both engineering expertise and practical experience. We evaluate these needs early on, ensuring every structural choice is made with precision for lasting stability. Ultimately, a well-planned double storey extension does far more than just add space-it becomes a lasting element of the home.
Clients frequently face challenges in managing various trades throughout such a large project, as delays in one area can cause a domino effect in others. A double storey extension involves groundwork, structural framing, roofing, plumbing, electrics, heating, and finishing work-tasks that need careful sequencing. We act as your single point of responsibility, managing every aspect, so you never need to chase updates or sort contractor disagreements. A well-coordinated double storey extension means timely completion, built to specifications, and finished to the standards your investment demands.

We discuss your project in detail, assess site conditions, and furnish you with a transparent initial estimate based on your needs.
Our team creates detailed architectural plans tailored specifically for your double storey extension and oversees the process of obtaining planning permissions and building regulation approvals on your behalf.
Once all approvals are secured, we formalize a contract that includes a clear cost breakdown and a structured project schedule, ensuring that each stage of the double storey extension is well defined prior to starting work.
We take care of all groundwork, foundation preparation, brickwork, structural framing, and roofing, ensuring that the new extension integrates smoothly with the existing home in both style and structure.
We manage all building services including plumbing, electrics, heating, and ventilation, followed by complete interior finishing works, leading to a thorough final inspection and formal handover of your completed property.
Wet weather demands quick sheeting. Heavy downpours soak uncovered joists quickly, so carpenters batten down thick tarpaulins across upper ceiling plates before nightfall to stop moisture penetrating down through ceilings below. Cold mortar also cures slowly during damp winter mornings. We monitor temperature drops carefully before laying facing brickwork, shielding fresh pointing with burlap sheets against sudden overnight frosts.
Dry clay shrinks rapidly. Deep summer heat pulls moisture out of subsoil beneath garden walls, which matters when setting up a double storey extension in Clevedon near mature oak or ash trees. Trench sides can crumble into excavated footings if left open under baking heat for several afternoons. Concrete pours happen promptly once building control officers inspect the firm sub-base.


Radiators require sufficient water pressure. Adding several bedrooms and an upstairs en-suite across two new levels often overburdens an old compact combi boiler tucked away in your kitchen cupboard. Plumbers test static system flow at your boundary stopcock before connecting new copper pipework runs through the floorboards to verify pressure stays steady when multiple taps run.
Extra rooms draw heavy current. Adding power circuits for a double storey extension in Clevedon means examining the main distribution board under your stairs to see if spare ways exist. Electricians pull heavy gauge armoured cable through service ducts instead of overloading older fuse boxes.
Gutters must handle storm run-off. When a tall new roof pitch ties into existing valley gutters, old plastic downpipes can easily overflow across patio slabs during heavy storms. Roofers install wider hoppers and separate soakaway crates beneath the lawn so rainwater never backs up beneath lower roof slates.
Opting for a double storey extension is one of the most deliberate choices a homeowner can make, and it requires a carefully considered approach for its execution. We see each double storey extension as a precisely organized project where structural integrity, material selection, and finishing details are all held to the same high standard. With more than 20 years of experience in complex residential undertakings, we know how to elevate your home across two levels without undermining its character. The result is a cohesive addition that appears to be a natural part of the original property, not an afterthought.
From the first estimate through to the final handover, your double storey extension is managed entirely under our roof. We handle every aspect, from groundwork and structural framing through to brickwork, roofing, plumbing, electrics, and interior finishes, ensuring that each phase flows seamlessly into the next, without delays or inconsistencies. A double storey extension of this nature requires precise scheduling and effective communication, and our process is tailored to achieve just that. You work with one contact who comprehensively oversees all decisions.

Mucha Construction Ltd delivers Construction Company services within a precise 20-mile radius of Bristol.
Ground conditions beneath foundations drive costs apart. Poor soil, nearby mature trees, or hidden sewer mains require deeper engineered footings, while internal steel beam spans and drainage access also vary considerably between properties.
Uncharted underground services or sudden severe weather can pause digging. When unexpected buried pipes appear, crews must wait for utility surveyors or building inspectors to approve revised footing positions before resuming bricklaying.
Finalising kitchen and bathroom layouts too late causes disruption. Choosing sanitaryware positions after floor joists and plumbing risers are fixed forces trades to alter structural timbers or re-route waste lines through finished masonry.
Having architectural drawings and structural calculations ready helps immensely. Clear plans allow estimators in Clevedon to measure exact quantities of masonry, structural steel, and timber joists without guessing wall thicknesses or roof loads.
