Exterior Finish

Choice Of Finish

External Wall Insulation — Rendered Finish

A rendered finish is a protective, decorative, and durable coating applied to exterior walls. Made from materials like cement, sand, lime, or silicone, it shields exposed brick from weathering, prevents erosion, and improves aesthetic appeal and value.

Cladding — Woodgrain Composite

Our woodgrain composite cladding achieves a real wood effect without the effort. Extremely low maintenance — no painting, staining, treating or sealing. Easy to clean and can be installed vertically or horizontally.

Brick Slip Finish

Thin, pre-cut slices of brick bonded to the substrate to create the appearance of a traditional brick wall without the weight or complexity of full-thickness bricks. Suitable for internal and external applications.

Roofing

Roofing Type

Pitched Roof

A sloping triangular roof design with sides meeting at a central ridge, offering better rainwater drainage and potential for attic or loft space.

•Aesthetic compatibility with traditional home styles.
•Increased vertical space or storage in the ceiling void.
•Greater natural lighting via dormers and skylights.

EPDM Roof

EPDM rubber roofing is a durable, waterproof slightly angled system made from Ethylene Propylene Diene Monomer synthetic rubber membrane.

•Resists cracking and UV damage — lifespan often exceeding 50 years.
•Installed in large single sheets, reducing seams and leak risk.
•Minimal upkeep after installation.
•Cost-effective compared to pitched roofing.
