"Hired them 9/6/2025. They sent out a third party to measure the home. That third party never provided Evolution the measurements. Evolution sent out another third party and they measured the house at something like 2,400 sq ft. We were provided a draft of the house and almost all the measurements were off. We communicated with Eliza and Collin but the corrected drafts were inaccurate as well. All we were trying to do was convert a golf cart garage to a closet and connect an existing bathroom to that closet, which would have increased our square footage from 1,490 sq ft to 1,610 sq ft. We sent the accurate measurements that we took ourselves to Eliza on November 18, 2025. Today is December 29, and despite a follow up call to Collin a few weeks ago we still haven?t heard anything from her. Fortunately we only spent a few thousand dollars on these clowns and have now found a reputable local company who has many more five star reviews on Yelp and this site. Avoid them at all costs!!"

"I was referred to Phani at AxisTerra Design by structural engineer I hired for my home renovation project to remove load bearing walls in living room. 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

Blueprints for standard home construction will usually range from $1,500 to $2,500 and average around $1,800. Your pricing will likely be higher if you’re building a custom home, as you’ll need to pay a structural engineer to weigh in on building safety. The size of your project, the number of rooms, and the type of drawings you need can also play a role in your total cost.

Arched windows used to be most prevalent in more traditional home styles, like Spanish colonial and Gothic, but they are becoming increasingly popular in modern design. You’ll often find arched windows in new home builds across many styles, including farmhouse and contemporary architecture. This represents a more general trend toward more unique houses with interesting features.

Get prepared to meet with an architect by having a clear idea of what you’re looking for, a list of questions to ask, and as many project details as you can provide. The more information you can provide and receive from a prospective architect will help you decide who to hire.

The various types of architects can be broken down into eight distinct categories, but there can be specific specialties within each of them. Most homeowners will work with a residential, restoration, green, interior, landscape, or retrofit architect for projects. There are also lighting and commercial architects whose work is geared more toward large spaces and businesses.

An architect ensures compliance with building codes, maximizes space efficiency, enhances functionality, and integrates energy-efficient solutions. Their expertise can also improve workflow and customer experience.
