2A CONSTRUCTION – START OF EXTENSION WORKS

Another project underway! Our team has officially started the rear extension construction, and the first phase is progressing exactly to plan. ✔ What’s been done so far: • Full site preparation and safe access setup • Demolition of the old rear wall • Structural openings created for the new steel beams • Installation of temporary supports • First lift of blockwork and brickwork underway • Setting out walls, levelling and aligning with high accuracy • Preparing for the steel installation and continuation of the external walls ⚡ Focus of this stage: Creating a strong, safe structural shell that will support the new extended living space. Every block, brick and beam is set according to building control requirements and engineering drawings. 🏡 End result: A modern, open, spacious ground-floor extension that will transform the rear of the property. More updates coming soon as the structure rises. If you’re planning an extension, loft, or full renovation — 2A Construction Ltd is here to deliver quality from start to finish.

Rear Extension & Structural Transformation

This project showcases the full transformation of a North London property through a complete rear extension and major structural reconfiguration. Our team at 2A Construction Ltd handled every stage — from demolition and steel installation to new blockwork, cavity walling, and structural openings — following all Building Control and engineering requirements. This rear extension project involved full demolition of the back wall, installation of new steel beams, and construction of a brand-new blockwork structure to increase living space and improve the home’s layout. We carried out all structural works safely using professional temporary support systems and completed the extension walls with insulated cavity blockwork for long-term durability and energy efficiency.
