Lees Building Contractors Ltd completed a high‑performance build featuring insulated cavity walls, a pitched roof and premium facing brickwork. This project delivers outstanding thermal efficiency and timeless kerb appeal, seamlessly integrating modern standards with traditional aesthetics.


Key Works & Features

  • Insulated Cavity Wall System
    Dual‑leaf construction using dense blockwork inner leaf, high‑performance cavity insulation and a weather‑resistant brick outer leaf.

  • Precision Facing Brickwork
    Selection of complementary modular bricks laid in Flemish bond, with flush‑pointed mortar joints for a crisp, uniform façade.

  • Timber‑Framed Pitched Roof
    Engineered roof trusses and rafters, breathable underlay and matching clay plain tiles or natural slate to mirror local vernacular.

  • Damp‑Proof Course & Cavity Trays
    Continuous DPC installation at all openings and stepped cavity trays above ground‑floor windows to prevent moisture ingress.

  • Window & Door Integration
    Recessed reveals with ideally aligned brick arches or soldier courses, ensuring water shedding and cohesive detailing.


Specialist Techniques & Materials

  • Cavity Insulation:
    100 mm rigid polyisocyanurate boards or mineral wool insulation for a U‑value as low as 0.18 W/m²K.

  • Block & Brick Bonding:
    High‑strength mortar with lime stabilisers to allow breathability and accommodate thermal movement.

  • Roof Waterproofing:
    Permo‑vapour breathable membranes and anticondensation sarking beneath tile battens.

  • Bricklaying Precision:
    Laser‑level guides and raked joints to maintain perfect alignment and consistent joint thickness.

  • Thermal Bridging Elimination:
    Insulated cavity closers at lintels and reveals, plus insulated wall‑plate support.


Why This Project Stands Out

  • Superior Energy Performance: Cavity wall insulation combined with a well‑ventilated pitched roof reduces heat loss and lowers running costs.

  • Architectural Cohesion: High‑quality facing bricks and traditional roof tiles deliver a timeless look that complements any West Country setting.

  • Moisture Management: Professional DPC, cavity tray and breathable membrane systems ensure a dry, healthy building fabric.

  • Craftsmanship Excellence: Meticulous bricklaying and roofing techniques reflect Lees Building Contractors Ltd’s commitment to detail.
