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. "

Architects questions, answered by experts

Depending on project scope, complexity, and building size, architectural services for businesses typically cost between $2,000 and $50,000. Fees can be structured as hourly rates, fixed pricing, or a percentage of total construction costs.

In most cases, you don't need to hire an architect for a garage conversion. Your garage conversion contractor should have the skills and experience to help create your desired design. However, if the scope of the conversion is large and complex, and your budget allows, it's smart to hire an architect to oversee the design.

It can take anywhere from a few days to several months to draw up architectural plans, depending on the complexity of your project. Architectural plans are highly detailed documents that take time to complete, and any changes or alterations can significantly extend how long they take.

Greek Revival architecture was popularized in America in the early- to mid-1800s, around the time when archaeologists were discovering buried ancient Greek buildings. As a means of celebrating the democratic government in ancient Greece, American architects borrowed from those newly discovered buildings as a way to emphasize that America would remain a democratic country in the wake of the American Revolution.

Yes, professionals will offer tailored solutions to fit architectural and personal style preferences.
