Lees Building Contractors Ltd recently completed the turnkey construction of a bespoke ancillary building, seamlessly blending traditional craftsmanship with contemporary design. This standalone structure provides flexible living space—ideal as a guest suite, home office or gym—while complementing the character of the main residence.


Key Features & Materials

  • Facing Brickwork & Blockwork
    High‑quality Gault brick façades tied into dense blockwork for exceptional thermal performance and structural integrity.

  • Cedar Wood & Part Render Cladding
    Vertical cedar panels deliver a warm, natural aesthetic; contrasting rendered sections create a modern, low‑maintenance finish.

  • Natural Slate Roof
    A precision‑laid Welsh slate roof ensures longevity, weather resistance and authentic West Country charm.

  • Energy‑Efficient Construction
    Polystyrene cavity insulation, airtight detailing and high‑performance windows contribute to low running costs and sustainable operation.


Construction Process

  1. Foundations & Groundworks

    • Excavation and trench fill to engineer’s specification

    • Insulated concrete strip footing and screed base for a level, stable platform

  2. Superstructure

    • Reinforced blockwork load‑bearing walls

    • Full-height cavity insulation and DPC installation

    • Precision bricklaying with raked joints for visual depth

  3. Cladding & Render

    • Factory‑treated Western Red cedar fixed to vertical battens

    • Breathable, silicone‑based render over insulated boards for durable, crack‑resistant façades

  4. Roof Installation

    • Engineered timber rafters with breathable underlay

    • Hand‑dressed natural slate tiling, lead flashings and ridge finishes

  5. Internal Fit‑Out

    • High‑efficiency lighting, electrics and data wiring

    • Plasterboard ceilings, skim plaster and premium oak trim

  6. Finishing Touches & Landscaping

    • Quality uPVC rainwater goods and timber fascias

    • Soft landscaping with native planting schemes and gravel access paths


Why This Ancillary Build Stands Out

  • Seamless Design Integration: Careful attention to scale, materials and rooflines creates a harmonious link between the new building and the main house.

  • Durability & Low Maintenance: Weather‑resistant cedar, breathable render and slate roofing combine for decades of reliable performance.

  • Versatile Living Space: Configured with open‑plan interiors, natural light and flexible layouts to suit changing household needs.

  • Sustainable Practices: Minimised waste, recycled site materials and high‑performance insulation reflect our commitment to eco‑responsible building.
