Handle budgeting & tendering faster

In 2022 we relaunched taking into account a ton of feedback from users. Contractors are now vetted on their individual past projects, so we obtain a reference & confirmed images for each piece of work they’ve completed. We've listened to architects like you and made the platform so much more intuitive.  Finally, we’ve changed our business model so we don’t charge contractors a success fee, but a monthly subscription for ready-to-go tenders.

Right now, we’re focusing on improving our new cost calculator and the quality of contractor information shown on their profiles.

Our extension cost calculator has been designed by a RICS Chartered Quantity Surveyor to give you or your client an estimate for the cost of a house renovation. We use the RICS NRM 1 construction standard in our methodology, which specifies a set of measurement rules that can be understood by anyone involved in a construction project.

For free, we can vet any contractor you want. For example if you come across one out in the field or you get a recommendation by your client. We will put your builder through the same stringent vetting method (you can read more on how we vet here) that we do for all Weaver contractors, and show up any red flags.

To get started on this, simply login and enter a project you’d like the contractor in question to potentially tender on, and you will see the request show up.

Having helped over 1,800 projects so far (most architect-led), we’ve learnt that getting your client 3 quotes from quality contractors is the magic number. One quote just doesn’t give you a price comparison. Too many though, and the best quality contractors drop out to avoid a messy bidding scenario.

You can ask us to introduce Weaver contractors as soon as you have designs drawn up. You can even start meeting builders with planning drawings only as some builders like to form new relationships early.

Projects usually come to us with sufficiently detailed information that allows a contractor to price accurately. To get your client a good market price, we recommend that your documents include detailed technical drawings, a schedule of work and structural engineering calculations.

Weaver is a platform that matches projects between £30k and £1.5m to main contractors mostly used by other architects. We verify each builder’s company information and call up their prior work references (you can read more on how we vet here) so you can be sure that they are the real deal.

Weaver is a venture-backed startup whose purpose is to celebrate the work of quality renovation contractors and inspire them to grow a super successful business. We do this by continuously evolving an easy-to-use platform that enables such builders to find projects that are ready to start on site. Read more here about Weaver’s story & founders.
