• Hi, we’re Mortar & Co.


Professional builders in Northamptonshire

We have an extensive range of building services designed to bring your ideas to reality.


New-builds, extensions, renovations


Offices, warehousing, industrial


End-to-end construction management

Construction projects are exciting, but also complex and risky. You need someone you can trust to manage your project through – from concrete to curtains.

That’s where we come in.

Mortar & Co is owned and run by Sege Rosella. You may have seen him on BBC’s The Dengineers (check out the video here), in his role as designer and master builder.

When not creating weird and wonderful dens he can be found putting his 34 years of experience in the construction industry to good use bringing your residential or commercial development to fruition.

If you’ve got any pressing questions about your upcoming project just give us a call or email – we’d be more than happy to help.
