What our clients have to say

As a client of Lateral Building Design for many years, we have found them to be professional and prompt and their attention to detail in assisting clients to gain both planning and building permits makes a complicated process easier for us as builders and for our clients.


I have been dealing with Mark for over 10 years now. I cannot thank him enough for sharing his knowledge, and it has been because of Mark’s wealth of knowledge and support that I have grown the confidence to branch out into the commercial sector of developing.


We have been working with John at Lateral Building Design for over 8 years and have developed a great partnership and appreciate his dedication to our projects. His attention to detail, creative approach and collaborative team work gives us the best possible outcomes for every project.

DEB TAYLOR, Taylored Building Solutions
