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. "

The referral is like god send in a stressful state where my home renovation project permit is pending for 2 months and San Jose city came back asking for kitchen architectural plans for permit issuance. Phani very quickly helped and provided the design plan in two days. He followed up with me multiple times to get all the details needed to avoid back and forth iterations. Phani shared the plans on the same night at 10 P.M. Once, I confirmed the next, he shared the stamped plans. I already referred AxisTerra Design to a friend for his home renovation project, and without any doubt or hesitation recommend AxisTerra Design for any home renovation project."

Custom Home Builders questions, answered by experts

Modular homes can be a great investment, especially for those who find the prices of stick-built real estate too high. Modular homes are usually much more affordable because they’re mass-manufactured and then assembled on-site or delivered mostly assembled. If they’re installed properly and by professionals, they can last for between 50 and 100 years, potentially making them an outstanding investment.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

Modular homes are cost-effective, energy-efficient, and faster to build than traditional homes. They also offer customizable designs.

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.

It is almost always more affordable to buy an existing home than to build one from scratch. First of all, new construction mortgage interest rates are often higher than traditional loans. Also, when building a home, you're covering the cost of brand-new finishes, appliances, electrics, plumbing, utility hookups, and labor. Between the cost of labor and permits, building a home will often cost more in the long run.
