G3 Consulting Engineers is a Glasgow-based civil, structural and geo-environmental consultancy with proven experience in the delivery of low-energy, low-carbon buildings. We help clients, architects, contractors and Passivhaus designers translate ambitious performance targets into practical, buildable and cost-effective engineering solutions. Our Passivhaus experience includes certified education projects, housing, and major flatted residential developments, including a hybrid-construction scheme that was one of the largest Passivhaus flatted developments of its kind at the time of completion. We have also supported a wide range of EnerPHit retrofit projects, including office-to-residential conversions, student accommodation and residential improvements for public and private sector clients. Through early optioneering, robust technical detailing and responsive construction-stage support, G3 helps deliver buildings that are efficient, durable, affordable and grounded in real-world buildability.
