Lynwood Grove Project
Project Overview
This comprehensive residential project transformed a family home through a carefully planned first floor rear extension combined with extensive internal and external alterations. The project successfully balanced the need for additional living space with modern sustainability requirements, creating a comfortable, energy-efficient home that meets contemporary living standards.
The scope included constructing a new first floor extension over the existing ground floor structure, complete renovation of existing spaces, installation of new energy-efficient windows throughout, upgraded insulation systems, air conditioning, roof-mounted solar panels, and a striking new external entrance with custom stairs. Every aspect was designed to enhance both functionality and aesthetic appeal while achieving LEED Gold certification standards.

Planning & Design Development
The project began with comprehensive planning and design development, working closely with the homeowners to understand their vision and requirements. Detailed architectural drawings were prepared, structural calculations completed, and all necessary planning permissions and building regulation approvals obtained. This phase included careful consideration of the existing structure, party wall agreements with neighbors, and coordination with multiple consultants to ensure a cohesive design approach.

Information required for this stage: Architectural Planning
Detailed architectural drawings showing the ground and first floor extension layout, new room configurations, and structural modifications were required for the project.
Design Consultation
Collaborative design sessions with the homeowners to finalize material selections, finishes, and spatial arrangements for optimal functionality.
3D Visualization
Computer-generated renderings helped visualize the completed extension and renovation, ensuring alignment with the homeowners' expectations.
Structural Engineering
Comprehensive structural calculations and engineering drawings for the new first floor extension, including steel beam specifications and foundation requirements.2
Site Preparation & Selective Demolition
With approvals in place, the construction phase commenced with careful site preparation and selective demolition. Existing structures requiring removal were safely dismantled, including the old conservatory, outdated windows, and internal walls. All demolition work was carried out in accordance with CDM regulations and health and safety requirements. Temporary supports and shoring were installed to protect the existing structure during the construction of new openings and removal of load-bearing elements. The site was secured with appropriate hoarding and safety measures to protect both workers and neighboring properties.

Structural Works & First Floor Extension Construction
The structural phase involved constructing the new first floor extension over the existing ground floor rear section. This included installing new steel beams and columns as specified by the structural engineer, building insulated cavity walls with rendered blockwork, and creating the roof structure. The extension was built with 350mm cavity walls incorporating 100mm partial fill insulation to achieve excellent thermal performance (U-value 0.18 W/m²K). New foundations were constructed where required, and all structural elements were carefully integrated with the existing building fabric. The roof structure combined both flat and pitched sections, with the flat roof utilizing a high-performance single-layer polymeric membrane system.

Weatherproofing & External Finishes
Once the structure was complete, focus shifted to making the building weathertight and applying external finishes. The flat roof received its high-performance Sarnafil polymeric membrane with a 20-year insurance-backed guarantee, while pitched roof sections were finished with plain concrete tiles to match the existing house. New thermally broken aluminum windows were installed throughout, featuring argon-filled low-E double glazing achieving U-values of 1.4 W/m²K. External walls received a two-coat cement render system to match existing finishes. This phase also included installation of new rainwater goods, lead flashings, and the striking new entrance stairs with contemporary design. Solar panels were mounted on the south-facing roof slope to provide renewable energy generation.

Internal Fit-Out & Building Services
With the building weathertight, internal works progressed rapidly. This phase included installation of all building services - electrical systems, plumbing, heating, and air conditioning throughout. Hydronic underfloor heating was installed to both ground and first floors, providing efficient and comfortable warmth. New air conditioning units were strategically positioned to provide cooling during warmer months. First fix carpentry, plasterboard dry lining, and plastering created smooth internal surfaces ready for decoration. New internal doors were hung, and fitted wardrobes installed in bedrooms. Bathrooms and shower rooms received high-quality sanitaryware, contemporary tiling, and modern fixtures. All work was coordinated to ensure services were properly integrated and concealed where possible.
