Stella did a great job for us. She liaised with building control (quite a challenge) and thought of things we would have never considered. Overall she did a great job for us and we are extremely happy with the outcome.

We used Ora Labora to get structural drawings for the removal of 5 load bearing walls. I had contacted many other structural engineer firms but they were hesitant to take on the project. When I rang Ora Labora there were no issues and they were able to come out quickly to survey the property. Everyone was very professional and I was able to get the final drawings very quickly at a good price. I handed these over to my builder and they were able to complete the work without any issues. I would highly recommend and would use them again!

We were referred to Ora Labora and it was a great referral. Stella came around and checked the property and had given us enough notice of where we needed to excavate for her to get a better understanding of the existing building. Drawings were submitted for our approval before final drawings completed. All done in great time, to me. Thank you Ivy for all your effort and communication as well. Well deserved 5 plus stars.

Highly recommended structural engineer. I was introduced by a friend to a very good and efficient structural engineer, Stella Macharia. She analysed the project and supported me during the process of new build on the 3rd floor. Stella attended at the site time stated and identified the issue straight away, and was very knowledgeable. I would highly recommend Ora Labora and her team and wish to continue to work with them for any future projects.
