An ADU can be a useful and practical addition to a property, providing a range of benefits to homeowners.
Maximize your property with an ADU, ideal for rental income, family, or guests. Designed for efficiency and sustainability, it’s a smart, flexible investment that adapts to your needs.

I used Pete and Genexsis for a large residential project here in Arizona and had a great experience. Pete was fast and thorough, but he also took the time to point out some potential issues with loading and building codes in the area. This saved me a lot of time and headaches during the permitting process. I highly recommend Genexsis for your next project.

Peter Frazier was exceptional to work with. He demonstrated remarkable attention to detail while truly listening to our needs, providing thoughtful options for our junior ADU plans. His approach strikes the perfect balance between professional expertise and personal care. We highly recommend him to anyone seeking a skilled building designer.
We have been clients of Peter’s on 2 new home build projects. We are very pleased with his high quality of work and amazing skills to capture our needs. He is very prompt and professional. We love referring him to others and we are extremely confident others will find him a highly regarded professional. It’s hard to find an honest person you feel comfortable,with, and he is all of the above. Thank you for your loyalty to our projects!
Peter Frazier was conscientious and engaged with us from the beginning stages of our project until completion. We added a Jack and Jill bathroom and also completely changed the facade of our home. Peter has a very professional service. He was engaged and attentive as we showed him pictures and ideas we sketched for our remodel. He drew up our plans in record time, made changes speedily and happily. When he submitted the plans for approval they were quickly approved by the city. I am highly recommending Peter and will definitely use again for our pool house!
