Contracts For Residential Build Projects

Do I Need A Contract With My Builder For A Home Extension Or Building Renovation Project?

Yes, of course we’re going to say there should be a contract, we’re a law firm!

It is common to find in smaller residential building projects that there is no formal written agreement been made between the homeowner and the builder. Instead, the requirements for a contract to exist (offer, acceptance, consideration and intention to create legal relations) are satisfied through a combination of quotations, exchanges of emails, telephone calls, meetings and invoices.

This creates a number of difficulties in establishing what is being done, when it will be done, and how much it will eventually cost and how it will be paid for. In such cases, we refer to your statutory rights eg: CRA 2015 it dictates the terms of the contract, price of the service and service to be supplied.

For that reason, it is important to make sure you have spent the time ensuring an appropriate contract that details your project is in place before work is started it could help avoid expensive and time-consuming disputes at a later stage if issues or disputes arise during the work.

Two of the most common causes for dispute in any construction project are variations and delay.

Failing to reach a clear agreement about what is going to be done and what is covered by the price will often lead to disputes, in particular about the standard of finish and variations.

There can also be an issue about the time for the works to be completed and how time and cost risks will be allocated between the parties. There should be a completion date, an understanding of how that might be extended, how the cost might change and what the consequences of delay are. Failing to address this can give rise to real issues for the parties’ planning, in particular about when the property will be occupied.

Finally, you can also have homeowners deciding to take on responsibility for some or entire project themselves, so in effect directly hiring a number of different contractors for different parts of the project, in particular for more “creative” elements of the works.

Another common approach is to omit elements of the project as it is progressing and source an alternative “specialist” to carry out that part of the project. This just multiplies the problems above, and can also create causation issues about which of several contractors are responsible for a particular delay or loss.

There are many different types of standard form contracts for projects involving work on a home. It is possible to use a bespoken contract as the choice of contract can be governed by the needs of the parties and the project. In either case, the contract would need to be suitably updated to keep track of any changes in the consumer law regime.
