In Finchley, our structural engineering expertise was showcased through a comprehensive project involving a rear and ground floor extension, coupled with a loft conversion. Central to our role was the development of precise structural drawings and intricate calculations, which laid the groundwork for this transformative endeavour. Given the proximity of mature trees, a specialized foundation design was paramount to counteract potential soil movement and root interference. Our team addressed this challenge by formulating a foundation solution tailored to ensure stability while preserving the health of the nearby trees. This holistic approach not only facilitated the seamless execution of the project but also underscored our commitment to marrying innovation with environmental mindfulness. Through our detailed designs and calculations, the property in Finchley was not only expanded but was reinforced to stand the test of time amidst natural challenges.
