Our modular homes are highly customisable with a strict focus on attention to detail, energy efficiency and build consistency. 

I was very pleased to get a chance to visit Totally Modular’s development in partnership with Citizen and Coventry City Council in my Constituency. It was extremely useful to hear first-hand about the cutting edge of modular housing. I was greatly impressed not only with the quality of the finished product but also with the speed in which it had been assembled and then constructed.
