Local Challenges

House Extensions in Waltham Forest

Extending a terraced house in Waltham Forest often involves navigating shared boundaries and party wall considerations. Structurally, the challenge lies in creating wide openings in existing masonry walls while supporting the floors above. We design efficient steel box frames or 'goalposts' to achieve this. Soil conditions can vary, influencing foundation design, from traditional trench fill to piled solutions if poor ground or nearby trees are a factor. Our designs address these local specifics from the outset.
