Brian V. came over to check out our house and to see if our expectations were realistic. He was very calm and organized. We found him very knowledgeable, especially about the San Mateo County permit & planning department. We interviewed a couple of other architeture firms, but found Brian at The Kastrop Group to be the best. Once we hired Kastrop, Brian quickly set up a time to come measure the entire house. Our 80 year old cottage had no central air/heat, so Brian referred us to an engineering firm that would help work out all the  computations that the permit department would need to approve this addition. As we moved through the architectural design process, Brian came up with solutions that would give us what we needed, along with a few suggestions that would provide more storage near our new second bathroom. We found Brian and Kastrop to be very accomodating with no drama. We like it when there is no drama. Once the architectural drawings were approved, we wanted to know if we had budgeted enough for the renovation. So, Kastrop had a General Contractor look at the plans and visit our house to give us some preliminary numbers. This was a big help for us and we were so thankful for this extra step. The Kastrop Group is an outstanding architecture firm that took us through the entire architecture design process with a gentle hand and no drama. We were grateful for their professionalism and their recommendations. If you are considering renovating your house, your first stop should be The Kastrop Group for impressive architectural expertise and being a great partner to navigate the county permit process.

From the outset, Geoff and his team demonstrated an exceptional understanding of our family's needs, which they transformed into a beautiful house design that resonates with our aspirations and lifestyle. We are currently transitioning to the construction phase, and are excited to raise our family in such a thoughtfully designed space. Also, Geoff and team are true experts at navigating the San Francisco permitting process. They efficiently moved us through permitting, both reacting to feedback from the city and helping us manage our neighbors. Honestly, we could not have permitted the house without their guidance. In a city where building homes can be difficult, the one two punch of beautiful design + the knowledge and skill to get it across the line was invaluable. We are so appreciative of Geoff and team.

From the first meeting, the team took the time to understand not just how we use the space, but also what kind of atmosphere we wanted for family dinners and evenings with friends. They proposed solutions that were modern yet warm, clean lines natural materials and lighting choices that make the space feel inviting without being overdesigned. What I really appreciated was their attention to detail. Things like flow between the kitchen and dining area, sightlines to the garden and even how the furniture would interact with the architecture, all of it was considered. Communication was excellent throughout: clear updates, quick responses and they navigated the city requirements smoothly so I didn't have to. The result feels both stylish and deeply livable. Hosting dinners now feels effortless, the layout encourages conversation and the finishes add just the right amount of elegance. If you care about design that balances beauty with functionality, this team delivers. They're not just designing a house, they're designing a home.

We purchased an older, fixer upper on a hillside in Portola Valley with the hopes of rebuilding it…read moreinto our dream home. We aimed to generate income by converting the former primary bedroom into a rentable, attached JADU. This mean building a new primary BR on the back, downhill side of the house, along with creating a new family room, and office. The front of the house was definitely old style, and did not, in any way, match our vision of a contemporary, hi-tech, look. I had interviewed other architects who had suggested we add a new front foyer, but I wasn't thrilled about the look presented, which was basically to add a gable roof addition ("A" frame shape add-on) at at the front, that would be harmonious with the rest of the house. In my first meeting with Davide, he suggested something that changed the whole dynamic of the house. He suggested that rather than be constrained by trying to harmonize the new entry with the old architecture, we could add a new layer to the front of the house, and change the look completely. This also creates a new corridor at the front that greatly improves the flow/circulation from the front to the back. It was a genius idea! This new layer at the front of the house gives us a spectacular new front entrance, plus a new corridor with tall ceilings. He also very skillfully raised the ceiling heights in many parts of the house so it feels like the rooms were expanded (when only the height changed). I am attaching a photo of the original house and Davide's concept for the new design. I want to add that we are not demolishing any part of the old house so we are not losing any existing square footage. We are just adding and "splicing the old with the new". For the new room additions at the back, he integrated the complex siting of the hillside PBR & family room to flow seamlessly into the same level of the existing house on. I have very strong ideas of what I want in terms of design, and Davide has been very patient in working through my ideas. He uses his critical eye and design experience to guide me so I don't get off track, and we can get to where it is I want to end up. We are now in the building permit process, and I can't wait for construction to start. I will be updating this post when the house is finished with more photos, because I want to show off the dramatic transformation between the "before" and "after". If you are looking for a miracle transformation, Davide Gianella is the architect who can make this dream come true for you! I can recommend him 100%

The good news is that he was so fair and honest; he really watched costs which is so unusual, and in the end, I could be so much more innovative and creative and do so much more than I could have been with any another contracting firm; even more importantly, we had such a good time working together (even the demolition which I dreaded was a piece of cake because of Doug). I left throughout the remodel on many business trips, & there was so much progress and usually a surprising new touch Doug added every time I returned home. Since then, Doug has been there for me on many other occasions. The good news is that Doug is happy with and enjoys smaller remodeling jobs as well. Last year my outside deck came away from its stucco wall & needed a complete retrofit, including adding more structural columns to further support the deck.
