“We pride ourselves on listening to our customers and creating homes they love”

– Ross Malone, Bloom Founder


We manage building projects from start to finish.

We provide fixed costs for projects based on the project plans, labour, materials and project management costs.

We bring together the team needed to get on with the build including engineers, designers, surveyors, the build team, specialists (such as AC contractors etc) and finishing decorators and tilers.

We’re on site daily to check on the progress and deal with any issues before they become a problem and manage the cash flow of the project to insure everyone is correctly paid for what they’ve done and our client’s protected throughout.

We’re only complete when everyone is happy and then return to site 6 months after completion to fix any minor issues. The work itself is guaranteed by the builder for 6 years.
