She guided us through our bathroom design with multiple options and a great eye for detail. Professional, friendly, and very knowledgeable. Highly recommend.Posted on Google Joan BrockTrustindex verifies that the original source of the review is Google. We had an amazing experience working with Jenna on our first-floor remodel and kitchen. Jenna really listened to how we live and turned our ideas into a space that’s both beautiful and highly functional—our kitchen is now the heart of our home. Jenna was creative, detail-oriented, and great at staying within budget. Communication was smooth throughout, and Jenna worked seamlessly with our contractor, making the whole process easy. We love the final result and would highly recommend Jenna!Posted on Google Aidan MurphyTrustindex verifies that the original source of the review is Google. Love Jenna!! She's so great!! She was introduced to me by a builder/remodeler when I needed floor plans for an investment project. She did a great job and I called her again when my wife and I wanted to add a bathroom to my own home. The space where we wanted the bathroom was unique. Jenna came up with great ideas and great plans that we would not have thought of or designed on our own. I can't wait to call Jenna back for the next project!!Posted on Google Cindy LuongoTrustindex verifies that the original source of the review is Google. I was in need of an architect to help design my ADU and was referred to Jenna by a friend. From the very beginning, she was fantastic. After signing our contract and agreeing on start and completion dates, Jenna was actually able to begin the project ahead of schedule. She kept every meeting on time, truly listened to my design ideas, and was incredibly creative in helping me maximize my space. What stood out most was how genuinely excited she was about my project — her enthusiasm matched mine every step of the way. Jenna was also extremely helpful in coordinating with the local building department commissioner regarding permitting, as well as working with the surveyor to finalize the footprint on my plot plan. Her professionalism and communication made the entire process smooth and stress-free. I would highly recommend Jenna to anyone looking for an architect for addition plans, ADUs, or any residential design project.Posted on Google Dylan MetcalfTrustindex verifies that the original source of the review is Google. We had an great experience working with Jenna on the design plans for our new garage. She was friendly, knowledgeable, and always quick to respond to our questions and feedback. Jenna’s thoroughness and attention to detail, especially when it came to zoning and planning requirements, made the permitting and contracting process incredibly smooth. We highly recommend her and look forward to working with her again on future projects!Posted on Google Lara RubinsteinTrustindex verifies that the original source of the review is Google. Jenna was excellent to work with! She is warm and friendly. From our first meeting Jenna listened well to my vision for our home extension project and created plans to make that vision come to life. We live on an unusually shaped, relatively small lot and Jenna was able to tow the line of giving us as much space as possible for our extension while being mindful of zoning laws and building codes. She was also thoughtful about details I had not thought of to make the space feel bigger (hello vaulted ceiling!). She helped guide us through the building variance process for the project, attending the zoning board meeting with me and making the whole process a breeze. I felt very comforted by her competence and expertise in navigating the variance process. You are in good hands with Jenna!Posted on Google M. Goodman-KhanTrustindex verifies that the original source of the review is Google. Our experience with Jenna was fantastic! She is very talented, responsive and kind. Her ability to understand our wants paired with the use of 3D renderings made it easy to understand the possibilities. Her creativity and professionalism shone through every step. Highly recommend! Thank you Jenna!!Posted on Google martha vatalaroTrustindex verifies that the original source of the review is Google. My family and I needed an architect to create an accessory dwelling unit (ADU) in my daughter and son-in-law's backyard in Arlington. As I'm 76 years old, it was to be my retirement home. All the small, in-law suites I'd seen were sad spaces over garages. I didn't want that. It was my lucky day when I met Jenna Ellison. Jenna listened to all my dreams for the space: an open studio, high ceilings, drenched with light from many windows; a minimal 500 square foot space with a huge walk-in closet, full Scandinavian kitchen, full-sized laundry, 9'8'' ceilings, a spa-like bath and shower; and a deck to connect to my children and grandchildren, but a separate structure and separate entrances. Jenna is wonderful architect who listened and then produced many designs for me until we arrived at what I have now. Further, she always had insight into how to solve a design problem that we encountered along the way. For example, I wanted a minimalist look, but was somewhat fearful it would look too "cold." One way she solved that was by adding some interesting character to the ceiling design near the kitchen. Another insight she had for my space was the transoms we installed above my double windows and sliders to deck. Also, we had a some issues with zoning that we solved with her help and attendance at zoning meetings. There were dozens of technical or design issues she solved. When folks first see my studio, the two comments I usually hear besides, "omg this place is awesome," are: "expensive hotel suite," or "fancy airbnb." My grandson says he's sixteen steps to my door and I could not be happier living here. It's like an upscale treehouse. My home delights me everyday and I have Jenna Ellison to thank for its design. You would never regret hiring her. Martha VatalaroPosted on Google smita okeTrustindex verifies that the original source of the review is Google. We met Jenna when we decided to renovate our home.
