Structural services
Why choose a chartered structural engineer? Not all structural engineering services are equal. Chartered Engineers (CEng) have met the highest standards of training, experience and professional accountability set by the Engineering Council. When you commission Dan Green, you’re working directly with a fully qualified, personally accountable engineer — not a technician working under someone else’s sign-off.
This matters for loft conversions, extensions and structural alterations because the calculations directly underpin your Building Control application. Errors or omissions can delay your project, cost more to fix, or — in the worst cases — create real safety risks. Chartered status means the work is done to the standard your building deserves.
Practical structural advice for extensions, internal alterations and loft conversions, shaped around your existing home.
Clear guidance for basements, underpinning, condition surveys, defect investigations and pre-purchase structural appraisals.
Retrospective assessments, PDF calculations and structural layouts to support thoughtful, well-managed building work.
Practical expertise
Led by Dan Green MEng CEng MICE, GPSS combines chartered expertise with practical, personal involvement in every project.
