Will Makepeace

Having studied Civil Engineering at university and a passion for more sustainable construction led to the world of timber frame design.

 

Experience designing a German advanced closed panel system honed in his eye for detail as extremely high accuracy was required and also provided a deep understanding of timber frame MMC design and procedures for offsite construction of commercial buildings.

 

Working on the first Passivhaus school in Hampshire for Willmott Dixon led to a specific interest in the Passivhaus standard. This along with the desire to broaden his experience both into residential and more specialist buildings as well as working on a broader array of timber frame construction methods lead to joining Cullen Timber Design.
