Quarry Architects (formerly Lytle Associates Architects) is an established architectural practice based in Guildford, Surrey, with a strong reputation built since 1987. We deliver projects across Southern England and London, combining decades of experience with a cohesive approach to sustainable design.

We can deliver low-energy, high-performance buildings, with our growing expertise in both Passivhaus and EnerPHit projects. Our design process integrates advanced tools including Building Information Modelling (BIM) and the Passive House Planning Package (PHPP), enabling us to accurately predict and optimise energy performance, thermal comfort, and indoor air quality.

From project inception through to Passivhaus certification, we guide our clients through every stage of the Passivhaus journey, ensuring a clear, collaborative, and informed process.

At Quarry Architects, we are committed to reducing environmental impact and see it as our responsibility to design buildings that contribute positively to a more sustainable future.
