New Ancillary Build – lees-builders

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.

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.
