Chartered structural engineers and building surveyors delivering accurate, reliable assessments and designs for residential, commercial, and heritage projects across the UK.
Full structural calculations for extensions, loft conversions, beam installations, and new builds. All calculations are produced in accordance with Eurocodes and relevant British Standards and are accepted by all UK building control bodies.
RICS Level 2 and Level 3 building surveys for residential and commercial properties. Our surveys are thorough, clearly written, and provide honest advice on condition, risk, and maintenance priorities — not just a list of defects.
Full party wall services under the Party Wall etc. Act 1996. We act as agreed surveyor, building owner's surveyor, or adjoining owner's surveyor — providing impartial, clearly explained guidance throughout the process.
On-site structural inspections and condition assessments for a range of purposes — from subsidence investigations and crack surveys to pre-purchase structural checks and insurance claim support.
Specialist structural assessments, calculations, and designs for listed buildings, buildings in conservation areas, and other historic structures. We work closely with conservation officers and heritage architects to find sympathetic, approvable solutions.
Independent structural engineering expert witness reports for legal proceedings, professional negligence claims, insurance disputes, and adjudication. Reports comply with CPR Part 35 and are produced by a chartered engineer with court experience.
Colton Structural has been providing chartered structural engineering and building surveying services since 1998. We are an independent practice — not part of a large corporate group — which means every report, calculation, and inspection is handled personally by a qualified chartered engineer.
Our clients include homeowners, property developers, architects, solicitors, and insurers. We are instructed at every stage of a project — from pre-purchase surveys and planning applications through to detailed structural design and expert witness work.
We hold full professional indemnity insurance and are registered with both the Institution of Structural Engineers and the Royal Institution of Chartered Surveyors.
