Quick summary

Yes, you can project manage your own home extension, but it’s only practical if you have plenty of time and resilience. It’s very time-consuming, often requiring daily site visits, and can take longer than professional management—sometimes adding extra costs. Be prepared to handle upheaval, organise documents, and hire reliable contractors carefully.

What do project managers do?

A project manager is there to organise the creation of your build, making sure your project is completed on time, on budget, and has a quality finish. They’ll oversee contractors and/or subcontractors, and deal with building controls, health and safety, and the utility companies. On top of this, they’ll also be coordinating any other professionals involved, such as your structural engineer. Basically, they wear a lot of organising hats.

Could I project manage my own build?

Project managers can cost between 15-25% of your construction budget. The smaller the project, the higher the percentage. So, it’s no surprise that some people opt to become their own project managers. However, there’s a reason a professional option exists - project management can be a lot of work! Here’s some things to consider before you take on the task.
