We pride ourselves in our ability to listen to our client’s wants and needs and to create a design which will satisfy their goals, within their budget. Each project is as unique as the client and the land it sits upon. Our talented team utilizes years of experience and cutting edge architectural drafting software that in the end will deliver you a fully dimensional build ready set of plans. During the design and drafting process you will work side-by-side with one of our very experienced team members ensuring you end up with the new construction, addition or renovation plans that meet your needs and wants. The exciting part is that throughout the process you will see your ideas evolve on a very large design monitor in full color 3D. We help take the confusion of black and white line drawings out of the equation. If you already have a set of those confusing black and white line drawings and you want to be sure it is the right plan for you bring them in. We will convert them to 3D to virtually turn, tip, flip, tour, change colors, textures…you name it. You won’t believe your eyes. More importantly you might avoid the very costly mistake of building from plans you don’t fully understand. If you think your project is too big or too small for this service think again. Our design portfolio ranges from a half bath and front entry makeovers to homes and light commercial over 10,000 square feet. See our portfolio for examples. ### Services Provided - 3D Rendering - Architectural Design - Architectural Drawings - Basement Design - Bathroom Design - Building Design - Custom Homes - Deck Design - Drafting - Energy-Efficient Homes - Floor Plans - Garage Design - Green Building - Handicap-Accessible Design - Home Additions - Home Extensions - Home Remodeling - Home Restoration - House Plans - Kitchen Design - Laundry Room Design - Modular Home Additions - Mudroom Design - Multigenerational Homes - New Home Construction - Site Planning - Space Planning - Staircase Design - Sustainable Design - Universal Design ### Areas Served - Santa Maria - Hanford - San Luis Obispo - Paso Robles - Orcutt - Atascadero - Lemoore - Arroyo Grande - Los Osos - Grover Beach - Morro Bay - Templeton - Pismo Beach - Cambria - San Miguel - Cayucos - Avila Beach - Santa Margarita - Edna - Garden Farms - Creston - Hanamaulu - Hanamā‘ulu - Kapaa - Kapa‘a - Kealia - Kōloa - Lawai - Lāwa‘i - Lihue - Po‘ipū - Puhi - Wailua Homesteads - ‘Ōma‘o ### Typical Job Cost $5,000 - 2 million We have completed projects in every price range.

Aaron was very helpful with thoughtfully utilizing our existing floor plan and reconfiguring it to maximize our usable space. The remodel is completed now and has a very comfortable layout and takes advantage of the views. Aaron also seamlessly interfaced with the county of SLO to obtain permits and assist with getting the project to a shovel ready start. ### All 14 reviews **★★★★★ — Steve Gregory, Feb. 2026** > Ganage Design has done really excellent work for my last three projects. Aaron is very efficient at getting projects through the City and the County in our area. His communication skills are great. He is able to assist with your design and what you would like to have at the completion of your project. I will be using Ganage Design many more times. **★★★★★ — Brian McLean, Feb. 2026** > We have experienced the permitting process with our county 3 times. With Aaron, it made the permitting process as easy as it could be for this county. His ability to get everything together to submit a complete package from the soils engineer to title 24 to the county made our struggles minimal. His communication with us was great, communicating when a signature or something was needed. We will definitely use him again. **★★★★★ — mnwhitmoyer, Feb. 2026** > We used Gannage Design for a complete rebuild of a 1950s house.

I would highly recommend him for your project. **★★★★★ — William Matuk, Feb. 2026** > We called on the Gannage Design Team to assist us with design services for our 4,300 square foot modern style home in Paso Robles.

We have a future new custom home upcoming and will definitely be calling on them for their expertise. **★★★★★ — Nagy Construction, Feb. 2021** > "I am a local Developer/contractor. Aaron Gannage designed a 3-unit apartment building that I purchased after is was approved by the Morro Bay Planning Commission. He finished the Construction documents and processed the permit through the city building department which was a tricky ordeal. Once the building was permitted, he help with field questions and changes to help make the construction process move smooth and efficiently. Aaron was very professional, knowledgeable and helpful. I would highly recommend Aaron Gannage with Gannage Design." **★★★★★ — HU-375982610, Jan. 2021** > I was referred to Gannage Design late 2018 for a remodel job. After meeting Aaron Gannage I felt very confident in hiring him to draw up the plans for a very large remodel job that would start early March of 2019. With his ideas and expertise he put together a design that was very satisfying and to my liking. My home turned out beautiful. I would highly recommend Gannage Design to anyone who needs a good and creative designer. In fact, a family member that loves the design of my home will be hiring Gannage Design to design their home as well. > > Jill **★★★★★ — slojw, Jan. 2021** > I would recommend Gannage design to anyone.

He has a good eye for practical design, which suited the needs of our project. He completed the job in a timely manner. He also handled all the building department paperwork and fees.
