THE PROJECT
From an idea
to a real space.
A SIP house extension in Harlow, combining composite cladding with a kitchen refurbishment.
Project Overview TRJ Construction Ltd has completed a remarkable house extension in Harlow, combining SIP panel construction, composite cladding, and a full kitchen refurbishment. The result is a modern, energy-efficient space that not only expands the home but also adds a stylish, contemporary touch.
1. Raft Foundation for Strength & Stability The project began with a raft foundation, providing a stable, durable base ideal for SIP panel structures. This ensures even load distribution and long-term structural integrity.
2. SIP Panels for Energy Efficiency By using structural insulated panels (SIPs), the extension benefits from superior thermal performance, airtightness, and quick construction, resulting in a warm and cost-efficient living area.
3. Modern Composite Cladding The exterior is finished with composite cladding, delivering a sleek, weather-resistant façade that complements the property’s existing architecture.
4. Kitchen Refurbishment As part of the transformation, TRJ Construction completed a full kitchen refurbishment:
Contemporary cabinetry and countertops
High-quality appliances and lighting
A layout tailored for functionality and style
5. Electrical Upgrades The team modernized the home’s electrical system, ensuring the extension is fully equipped to handle modern appliances and technology while enhancing overall safety.
The finished project is a seamless blend of design, energy efficiency, and craftsmanship. From the exterior cladding to the kitchen details, every element showcases TRJ Construction’s attention to quality and client satisfaction.
