We would highly recommend Gradwell Consulting to any client or building professional seeking expert advice on the energy efficiency aspects of the built environment.
Ben Humel | Director, Humel Architects
David always finds a way to comply with BASIX - even with complex glazing.
Luke Trovato | Gartner Trovato Architects
Despite giving Gradwell Consulting up to 25 units to assess at any one time, they still come through for us to meet market expectations with quick turnarounds.
Bernie den Hertog | Village Design Pty Limited
Gradwell Consulting have provided me with NatHERS modelling support and design advice for almost five years, across projects ranging from single house dwellings to apartment buildings with over 100 residences. David and his team are always prompt, accurate and prepared to assist – particularly when deadlines are tight. I cannot recommend them highly enough.
Graham Agar | Director, Full Circle Design Services
I often partner with Gradwell Consulting for very large projects.
