Corinth Contractors from the beginning was a delight to work with upon our project. Some issues arose through the works as it was a fairly large project but quick solutions were presented! The service and quality of work was great and their project programme really helped us keep track throughout especially when we needed to supply items! Very happy with the final product and we have recommended to friends and family when/if they do their houses in the future.

Architecture- 5 May 2018
Contracted to provide options for a new garage office and storage solution. They turned up promptly and were very polite and professional. Through many discussions they ultimately offered up a very good bespoke solution for our situation and once planning is approved we will have no issue with looking to them to complete the actual build. We have had a lot of issues in the past finding reliable trades but with ArhiTERRA design and build we felt confident in their ability to both visualise and implement the build as well as follow through on their promises. I would say that for anyone considering discussing a project with them that it is worth your time to at least have a meeting with them and judge for yourself.
