We provide structural design in steel, concrete, timber, and masonry for new builds, extensions, and conversions.

Services include roof design, retaining walls, and mezzanine floor calculations tailored to project-specific requirements.
Surveys & Inspections
Our comprehensive surveys identify structural movement, cracks, and defects using peer-reviewed methodologies. Engineers assess causes ranging from subsidence to material decay, providing detailed reports with remediation recommendations. Services support building regulation compliance, insurance claims, and pre-purchase evaluations for residential and commercial properties.
