Igino Pellizzari is the Sole Proprietor of IVP Design Studio. He has been involved in building design for over 35-years in the San Francisco Bay Area . From 2004 to 2012 he was a Principal and Director of Design of the licensed architectural firm Studio Abitare in Emeryville, CA. Currently Igino is providing his services as a Residential Building Designer under California Business and Professions Code 5537 that does not require a license. If the scope of a project exceeds Section 5537 limitations, then Igino works with a registered structural engineer who will provide the specifications and calculations for that scope plus sign and stamp the documents. This is an invitation to work together, to begin a conversation to understand your goals, explore options and opportunities, and get to know each other so that we may collaborate to arrive at the best solution to achieve your objectives. Igino would look forward to the meeting with you to start the process and begin next steps.

" After purchasing our historically registered Maybeck house which had been neglected for years, Igino worked with us to bring the house up to current building standards (new foundation, electrical, plumbing, and most recently, taking on the challenge of replacing a chimney situated in the middle of the house.) In addition to these basic but very important improvements, Igino worked his way through the rest of the house, interior and exterior, consulting with us and making updates in keeping with the design integrity of the home (including a full kitchen re-model.) Finally Igino re-designed and managed from the bottom up (foundation to new pitched roof) the construction of our backyard cottage for which he received a design award from the Piedmont Architectural Design Committee. Igino is a pleasure to work with. He listens. He communicates well. He pays attention to the budget. He’s dedicated to getting the job done right. "

Mark Brand Architecture's award-winning architecture and interior design studio balance high design with practicality, combining understated elegance with elements of drama. Our goal is to exceed our clients' expectations by maintaining a creative, enjoyable and efficient relationship between the owner, architect and contractor from the beginning of design through completion of construction. No job is to big for us, and we always deliver professionalism and excellent work to all of our clients. For an architect you can trust, give us a call today!

"Mark Brand asked all of the right questions and worked tirelessly with the city permit department to make sure everything we wanted to do would be approved. Beyond being amazing on the phone with the city, his design fit with our mid-century home and anyone who has seen it is amazed at the transformation of our small back yard. We started this project with Mark in 2019, long before COVID-19, and completed the major construction in October of 2020. The actual construction began in May 2020 with demo, to completion in October 2020. Mark and his staff were with us through the entire process, communicating with our Contractor and Pool installer and keeping everyone in the loop and on track. I had never worked with an architect before, and feel grateful that my first experience was with Mark Brand and his team. Fees are explained up front, and although the fees were a healthy part of our budget, I know I got what I paid for! Communication with email and phone calls, as well as site visits were always timely, with any issues explained and problems worked through and resolved to avoid delays."

Custom Home Builders questions, answered by experts

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.

Yes, there are a few different ways you can finance new construction. Some lenders offer new construction loans that cover the building costs and then convert to a standard mortgage once construction is complete. Some custom homebuilders also offer financing options that only require a down payment before you begin the building process. Construction loans are possible, as well, although they typically only cover the building process, and you’ll need to pay in full once the house is completed.

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.

Construction typically takes 3-6 months, including site preparation and assembly.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.
