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."

Architects questions, answered by experts

A blueprint is more detailed than a floor plan. There are different types of floor plans, one of which is a type of blueprint view. However, the blueprint will contain more information about that plan and is drawn to scale. Most residential floor plans give homeowners a simplified view of their construction project, while blueprints have all the details to turn that plan into reality.

Regular meetings, reviewing drafts, and providing input on materials help align the project with your vision.

When conducting space planning, building codes and regulations need to be considered. As long as you are taking them into account and discussing them with the architect, you should be able to do your space planning appropriately.

Palm Springs homes and similar mid-century modern architecture took off in Northern California, Seattle, and the Midwest. You'll also find many homes that emulate the style in northeastern states, such as throughout Pennsylvania and New York State. That being said, you'll have the best luck finding this style in its original home: Palm Springs and the surrounding area.

Renaissance-style architecture predates Italianate architecture and serves as an inspiration for many elements of the Italianate style. Renaissance architecture adheres to the rules of classical architecture, while Italianate architecture adds elements that served to modernize the Renaissance style for the Victorian era and allow this style of home to be produced in a range of sizes to be attainable for various budgets.
