This was our first time working with an Architect and Jessica Petty has made this process fun, exciting, and incredibly easy.  Before we embarked on this journey we had only an idea for our house.  Jessica has helped turn our idea into this incredible vision which has really excited us.   She has been great to talk and meet with, quick in response to questions, and is a very effective communicator.  We are still early in the journey to build our house, but we are so glad we chose Jessica to work with and look forward to continuing with her.

I recently enlisted the services of 12.15 Design LLC for a small commercial constructionproject in Boise. Jessica created the Site Plan for this project and helped with organizing all the s  for the Plan Review. Jessica was great to work wit and her detailed designs helped to streamline the approval process.

I have been in the construction trade for well over thirty years. I moved from California to Idaho last year and am in the process of doing my own home renovation. It has been difficult choosing companies and vendors you are not familiar with. So far I have been extremely fortunate. One of the more complex aspects of home renovation is rendering drawings and a design plan. This is where Jessica Petty came into the picture. After discovering her web site, I gave her a call. Jessica was professional, articulate and friendly. We made an appointment for her to measure my property and she was on time and prepared. It was an easy choice for me after our first meeting. From beginning to end Jessica followed through with her commitments to us, I am very pleased. Whether your project is large or small, I would not hesitate to recommend Jessica.
