Full property renovation and extension project in Hillman 

We delivered a comprehensive renovation project in Hillman involving the transformation of two joined houses into a single, fully modernised property. The works included significant floor reinforcement to ensure long-term structural stability, along with full internal strip-out to enable a complete rebuild. New extensions were added to both the front and rear, significantly increasing the living space and improving the overall layout and value of the property. 

 

The entire rebuild was completed in line with NHBC standards, ensuring high levels of quality, safety, and durability. We managed and executed the full process, delivering a seamless project from start to finish with a strong focus on precision and long-lasting results.

Multi-level educational facility development in Notting Hill

We delivered a complex, multi-phase development in Notting Hill combining education and sports facilities within a single structure. The project included the construction of a basement sports hall, designed with careful attention to ventilation, lighting, and usability for safe sporting activity. Above this, we built a series of modern classrooms to provide well-planned learning environments with a strong focus on space, acoustics, and natural light. 

 

At roof level, we introduced a fully functional sports pitch, maximising available space to integrate recreation within the facility. We managed and delivered the full project lifecycle, ensuring every stage met programme, budget, and quality expectations while aligning with stakeholder requirements.
