Latest Home Extension Build from Lees Building Contractors Ltd
At Lees Building Contractors Ltd, we’re proud to share the latest site progress from one of our ongoing home extension projects in North Somerset. This extension showcases expert craftsmanship, energy-efficient materials, and a combination of modern techniques and traditional detailing that Lees Builders are known for.
This update provides a look behind the scenes at our building process—from the foundations up to the roof—with specific focus on blockwork, brickwork, flat roofing, thermal insulation, roof lights, and glazing installation.
Blockwork and Brickwork – Solid Foundations
We began with a carefully measured excavation followed by concrete footings to meet the structural engineer’s design. From there, we constructed cavity blockwork walls internally, offering strength and excellent thermal insulation.
Externally, we matched face bricks to complement the existing structure of the house, ensuring the extension blends naturally with the original building. All DPC (damp-proof course) levels have been installed with precision, and cavity closures are in place to ensure full compliance with Building Regulations.
Our team also incorporated insulated cavity closers, ensuring thermal continuity and preventing cold bridging around the new openings.
Double Glazing and Roof Lights – Letting the Light In
With the block and brick walls now completed, we’ve installed energy-efficient double-glazed units. These high-performance windows reduce heat loss and enhance acoustic comfort while offering a modern aesthetic that complements the rest of the home.
We also prepared for the flat roof light installation. The roof light will bring natural light into the heart of the extension, brightening interior spaces and creating a sense of openness. The upstand and flashing are now built in preparation for the final fitting.
Flat Roof Construction – Modern, Durable and Low-Maintenance
Our flat roof system has now been fully constructed. Using high-grade timber joists, we created a robust framework before installing the necessary vapour control and breathable membrane layers.
Above the deck, we’ve laid thermal rigid board insulation to meet and exceed current U-value requirements. A durable single-ply roofing membrane will be applied next, offering a long-lasting waterproof seal with excellent resistance to UV and weathering.
The roof has been engineered to allow for subtle falls, ensuring efficient drainage without compromising on visual appeal.
Thermal Floor Insulation and Joists – Comfort Built-In
The floor system beneath the extension features insulated concrete slab construction, overlaid with rigid insulation boards. This system ensures high levels of energy efficiency and underfloor comfort.
Timber floor joists have been installed with laser-levelled accuracy, allowing for minimal deflection and long-term durability. Acoustic insulation has also been incorporated to reduce sound transfer and provide a quiet, peaceful internal environment.
What Makes This Extension Stand Out?
