Services
Loft Conversions
We specialise in transforming unused loft spaces into functional living areas. Our conversions include dormer, L-shaped, and hip-to-gable designs, tailored to property structure and client needs. Each project includes structural assessments, planning permissions, and energy-efficient insulation. Clients benefit from increased property value and maximised headroom.
Home Extensions
Our home extensions create additional living space through rear, side, or wrap-around additions. We handle full project management from design to completion, ensuring compliance with building regulations. Services include structural calculations, material sourcing, and integration with existing architecture for seamless results.
Design & Planning
We provide end-to-end design and planning services for loft conversions and extensions. This includes architectural drawings, party wall agreements, and building regulation approvals. Our team collaborates closely with clients to optimise space usage while adhering to budget constraints and local planning policies.
Dormer Loft Conversion
Dormer conversions add vertical roof extensions to increase headroom and floor space. We construct flat-roof or gable-fronted dormers, compliant with permitted development rules. Projects include structural steelwork, insulation, and interior finishing to create bright, airy living spaces.
L-Shaped Loft Conversion
L-shaped conversions utilise existing rear extensions to create dual-dormer layouts. Ideal for terraced properties, this design maximises space for en-suites or multi-room configurations. We ensure compliance with volume limits and planning regulations while optimising natural light and storage solutions.
