High-quality, structurally sound home extensions designed and built with precision
WHL Projects delivers bespoke extensions for homeowners and developers across the UK — from modest single-storey additions to large, architect-designed structural extensions. We focus on precision, buildability, and long-term performance, ensuring every project complements the existing structure and enhances the property’s value.
Our capabilities
We handle both design-and-build and traditionally tendered projects. From early feasibility advice to the final handover, WHL Projects manages the entire process — coordinating design, engineering, and delivery for a seamless result.
The success of any extension depends on how it connects to the existing building. Our engineering-led approach ensures correct sequencing, load transfer, and weatherproofing at every junction. We coordinate structural steelwork, floor levels, insulation continuity, and damp-proofing so that the old and new structures behave as one.
Our sister company, WHL Surveying & Engineering, provides structural verification and design input, ensuring all works are compliant with Building Regulations and structurally robust. This collaboration guarantees that every extension is safe, durable, and ready for inspection and certification.
Attention to detail defines our work. We match materials, brick bonds, and roof pitches to maintain the architectural character of the original property while integrating modern insulation and energy-efficient systems.
Internally, we manage all finishes — plastering, flooring, joinery, and decoration — to deliver a complete, ready-to-use space. Our tradespeople are experienced in high-end domestic projects, delivering clean workmanship and smooth transitions between old and new areas.
Most extensions take place while the client continues living in the property. We sequence works to maintain access, heating, and security throughout construction. Dust control, protection, and daily clean-ups are standard on every site.
We communicate clearly at every stage, providing schedule updates, site meetings, and transparent cost tracking. Clients know exactly what’s happening and when — no surprises.
All works are carried out in line with current Building Regulations for structure, fire safety, energy efficiency, and ventilation. We promote sustainable design through efficient insulation, low-energy lighting, and recyclable materials wherever possible.
We work closely with designers and building-control officers to ensure every extension meets current thermal and acoustic standards, helping homeowners reduce long-term running costs.
