House Extensions
Structurally Engineered & Fully Compliant House Extensions
Platine Construction Ltd delivers bespoke house extensions that enhance living space while maintaining structural integrity, regulatory compliance, and architectural coherence with the existing property.
From early feasibility and planning support through to structural coordination, construction delivery and building control approvals, we manage every aspect of the extension process. Each project is carefully planned to meet client requirements, site constraints, and statutory obligations while minimising disruption to occupied homes.
Structural & Design Integration
We coordinate structural engineering and architectural design to ensure extensions integrate seamlessly with existing buildings and perform safely over their full lifecycle.
Planning & Building Control Compliance
All works comply with local planning authority requirements and Building Regulations, including Parts A, B, L, F, and G.
Controlled Construction Delivery
Extensions are delivered under defined scopes, in-house trades, programme management, quality inspections, and cost controls, ensuring predictability and quality at every stage.
Minimal Disruption Approach
We implement site logistics, safety measures, and phased working strategies to reduce impact on occupied properties.
