Build Routes Explained
Choosing the right build route is an important step in your project. And one best made early on. Your decision will be shaped by a variety of factors, from budget and timeline to the level of involvement you want in the process. Understanding your options now can set your project up for success.
Route 1
MAIN CONTRACTOR
Leave it to the professionals with all work managed by a main contractor.
Pros
The main contractor oversees the entire construction project. You have one main point of contact.
The main contractor is responsible for managing and coordinating all construction procedures on site. You can essentially relax, watch it all happen, and be handed the keys once the project is completed.
If you choose this route, we recommend that you follow a rigorous tendering process, to find the right contractor for the job. If you hire the right team, you’ll get great results.
Cons
If you hire the wrong company, the results can be disastrous.
Since all responsibility is passed on to one contractor, you can expect to pay more.
Route 2
PROJECT COORDINATOR
Employ a project coordinator and a team of subcontractors for a balanced approach.
Pros
This is a practical option between the main contractor route, and self-managing the project.
The costs saved by subcontracting trades yourself can offset the cost of a employing an on-site project manager.
An experienced project coordinator will bring valuable expertise to your project, and as well as peace of mind.
Cons
The success of this route depends on an effective project coordinator.
Route 3
SELF-MANAGED
Take control of your project and directly hire subcontractors.
Pros
This is by far the most economical self-build route in terms of direct costs.
Project managing your own self-build can be highly rewarding.
Cons
This build route has a higher perceived risk, with site management left to non-professionals.
It’s demanding and daunting! To make it work, you need a good understanding of the self-build process, and a high quality team.
