"If you?re here looking for an architect, look no further. Francisco is the man for the job. He helped us with a garage to ADU conversion. Francisco kept us informed and communicated with us throughout the entire project. He was very professional, helpful and patient. We had tons of questions and he had the answers. He is very efficient and great at his job. We would hire him again with no hesitation. Thank you Francisco for making for making this process a breeze!"

"We did a full remodel of our place, full new kitchen, and expanded our place into the backyard for a new master suite. Pac Sands did a really great job with our designs. Great tools that made the communication easy with the plans and changes we needed. And they handled the engineering and permitting too, which was great. Highly recommend."

Architects questions, answered by experts

It is technically possible to draw your own blueprints, but the process is extremely involved and really demands help from an expert. A professional architect has an understanding of design elements, interior design, the functionality of different rooms in a home, and how everything from furniture, outlets, and light switches should be laid out to serve you and your family best. Hiring an architect for blueprints can get expensive, but it’s the most responsible way to begin a new construction project. If you’re keen on DIYing, you could consider starting the process and then having a professional take over.

Costs depend on project complexity, software requirements, and the draftsperson’s experience.

A floor plan is a less detailed illustration showing a building or room's layout from above, including elements like windows, doors, walls, and fixtures. It offers a simplified view for homeowners. In contrast, a blueprint is a more detailed, to-scale architectural drawing that includes all parts of the building plans, such as structural elements, construction details, and utility schematics. While a floor plan can be a type of view within a blueprint, the complete blueprint contains all the necessary details to turn the plan into a reality.

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.

Consulting the architect of your house is not the best way to determine when it was built. Many homes are built by developers or builders, so there may not be a specific architect to track down—especially if you have a very old house. Instead, it’s best to rely on local government records.
