Local Challenges

House Extensions in Greenwich

Greenwich presents unique challenges, from the sensitive historic context of properties near the World Heritage Site to varied ground conditions across the borough. Many homes, particularly Victorian terraces in East Greenwich, have tight access and are built on London Clay, requiring carefully designed foundations. Our engineers are experienced in addressing these local factors, ensuring foundation and steelwork designs are appropriate for the specific site conditions and architectural character.

Recent Project

Eltham, Greenwich

We designed the complete structural package for a wraparound extension to a 1930s semi-detached house, creating a large open-plan kitchen-diner. The design included a complex steel box frame to support the rear of the house and allow for expansive bi-fold doors.
