"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."

"Jeromes extensive experience with business TI projects made him the perfect choice for our needs. Hiring him was one of the best decisions we could have made. His exceptional skill, combined with his genuine kindness and honesty, truly set him apart. Culver City presents its fair share of challenges, particularly with the citys responsiveness, but Jerome and his team went above and beyond. They consistently communicated with the city on our behalf, advocating tirelessly to expedite the permit process and relieve so much of the stress on our end. Jerome dedication and professionalism are unmatched, and his commitment to his clients is evident in every step of the process. If you are looking for an architect with top-tier expertise who truly cares about his clients success, look no further. Jerome is simply the best!"

"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

Architects questions, answered by experts

The biggest upside to hiring an architect is that they will ensure an efficient building process without errors. They will also ensure your home is free from structural issues and that everything is up to building code. Many permitting agencies require architects to draw construction plans and layouts before working, so hiring an architect will also ensure your project is legal. Additionally, architects help homeowners have a clear idea of their project details before the project starts. Hence, they help unify all parties on a shared vision for the project.

If your project is complex, it may make sense to hire an architect to draw plans. An architect might also be a good person to hire if you want to ensure your plans adhere to building codes and regulations.

In most cases, you should hire a draftsperson for simpler projects like minor home renovations, and you should hire an architect for new construction, structural changes to your home, and large home add-ons. If you’re working on a larger project that demands an architect or structural engineer, your professional will often have a draftsperson on staff and include their services in your estimate.

You should have an architect involved in your project from the very beginning. They’ll be able to direct your vision into workable plans, and they can advise you on potential problems right from the start. You may be able to save money by not using an architect, but larger projects will go much more smoothly with an experienced pro directing the process.

A designer is a great choice for remodeling projects that don’t require significant structural work. For remodeling that includes structural work like removing load-bearing walls, altering exterior walls, or adding on a room, an architect can design and execute the renovations while ensuring your home remains structurally sound.
