Duffy Associates Ltd are primarily structural engineers, who manage the construction process from conception to completion. We are a team of architects, structural and civil engineers, surveyors and project managers. Understanding the client's requirements, we work through the proposed design to produce architectural and structural drawings for planning and construction. As the project progresses we supervise the works including cost management and any variations the client may require. We have successfully designed, managed and built residential and commercial projects throughout London and the Home Counties. Our solid reputation is built on over 25 years' experience working with private clients, international banks, pension fund holders, property developers, architects, interior designers, party wall surveyors and estates.
