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.

Extensions- 19 Jul 2021
Jitender/Tinku and his team were excellent from the first time we met. They provided us with ideas to better our layouts, helped with sourcing a number items and put us in contact with suppliers which helped us achieve more competitive prices. I was kept updated with the progress regularly and most importantly the project was completed on time and within budget. Shah Builders take real pride in their work and it shows in the finished product. We are very pleased with the outcome of the project and have recommended Shah Builders to friends and family.
