Estimate service for Architects and Designers

HBXL Professional Services is not just for builders. Our estimate service for Architects and Designers is brilliant for helping you provide your clients with a construction estimate.

Most architectural designers tell us that they’d prefer to outsource project costings and that’s where we can help. You can even charge a premium for the service your end and make a profit on our services! We are also much cheaper than a QS service, and provide customer friendly reports rather than detailed NRM/SMM7 style documentation.

Our prices start at just £99 for an extension and £199 for a new build.

So whether you’ve designed a new build, extension, garage or loft conversion that you would like an estimate for, our professional team will price it quickly and accurately.

Our service is totally bespoke to you and your business. Find out why we’re different.
