“We started working with Multiproject last year and they are now our go-to partner for cost consultancy on our projects. Everything is delivered quickly and professionally and has helped us make some important decisions. They even advised us not to go ahead with some projects even though it meant them losing out on revenue, they always prioritised our needs like it was their own business and that kind of transparency is golden in this industry!”

“Multiproject provided us with accurate construction cost estimation based on the up to date RICS and market data and precise material, labour and other costs. Bart and his team’s help in planning and managing our schedule and costs has been invaluable. My advice is for anyone thinking they can do it all themselves is to just give them a try. Multiproject are now a fundamental partner in our business now and we wouldn’t trust anyone else with our projects”
