Practical, Reliable Structural Engineering

Structural Design You Can Rely On

We help homeowners and architects turn ideas into safe, buildable structures.

With over two decades of experience, Apex Structural Design provides practical, cost-effective engineering across London and the South East.

Our Services

  • We provide full structural design for new residential and commercial developments, from early concept through to Building Control approval. Our designs are practical, efficient, and fully coordinated with architectural and services layouts to ensure a smooth construction process.

  • Practical, buildable solutions for home extensions, loft conversions, and structural alterations of existing buildings.

  • We support architects, developers, and contractors on a range of commercial and mixed-use schemes. Our experience covers steel, concrete, timber, and masonry structures, with an emphasis on efficient design, clear documentation, and coordination across the wider design team.

  • We design retaining walls, underpinning and detailing suited to challenging ground conditions. Our foundation designs are based on geotechnical data and local experience, providing stability, durability, and compliance with Building Regulations and NHBC guidance.

  • We offer foul and surface water drainage design for new developments, extensions, and redevelopments. Services include attenuation and soakaway design, Section 106 and 104 applications, and coordination with local authorities.

  • We carry out site inspections and prepare clear, comprehensive reports for structural issues, proposed alterations, or planning submissions. Reports are tailored to your needs — whether for a home purchase, refurbishment, or validation of existing structures.

  • We provide regular site visits to monitor construction quality and ensure compliance with our structural design. Early involvement allows us to resolve issues promptly, keep projects on track, and maintain close communication between the design team and contractor.
