"We had a great experience working with Eran. He is a professional and is an expert in his field for our specific project, he handled all the structural work for the seismic retrofit and when my architect had a melt down, he even stepped in and took on that responsibility too. He collaborated with us and we spent the time to understand our needs and where we wanted to take the project. He made our life much easier by getting the building permits and worked with the planning department and the inspectors. Invaluable. We look forward to working with him in our next phase and would recommend him for future work."

"Conrad was great to work with from beginning to end. We originally asked Conrad and 2 other landscapers for a bid on an existing backyard design that had been prepared for us by an architect. When we realized that the cost for that design was way out of our budget, we asked Conrad if he could change the bid to reflect the use of less expensive materials and simpler execution so we could reduce the overal cost without compromising the design. He came up with a design that was mostly faithful to the architect's vision, that accomplished our main goals for the space and was a fraction of the original bid. We hired him over the other companies because he always responded to every challenge and request with equanimity and an informed plan. He listened to what we wanted as well as what our parameters were, and worked creatively with us within our limitations. During the whole process, Conrad and his crew consulted with us regularly and were open to figuring out and executing changes that arose in the plans as the space evolved. Conrad always communicated clearly and responded promptly, thoughtfully to quickly to any questions or concerns. His crew was always prompt and respectful and they worked quickly and well. The work went so well, that they were finished almost a week ahead of their projected completion time. The backyard looks and functions much better than before and, most importantly, the drainage system works well to channel rain and run off away from our home. We're very pleased with the work Del Mar Landscaping performed for us! We plan to hire them again and I would recommend them to anyone as being fair, creative and professional in all aspects of their work."

"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!"

"I searched many and started off with others and nobody came close in handling what we needed. I found Richard, he came in and took care of it all; it was completed in a timely manner with his accurate thinking. He definitely thought ahead and it saved me a lot of time, grief and money. He got ahead of any issues and resolved potential problems that could arise. He knew exactly what the city would require and did what needed to be done which saved us an untold amount of time and money. I did not know him from Adam, he works at a very different level of ability and knowledge. His pricing for me was the best! He is a gem, get him if you can!"

"This company was one of the first to respond after putting out my request for work on HomeAdvisor. Wil is a very personable business man, his client relations staff is wonderful and they were able to begin work on the project in a reasonable amount of time from first point of contact. I loved the fact that Wilâ s company took on my smaller kitchen project, as most companies had a threshold amount of $4k and didnâ t want to be bothered. Wil has excellent contractors and walked through project with me upon completion. Heâ s got got my future business!"

"Leo was very helpful and quick to respond. We’re happy with how our 2 bathrooms turned out. Project was completed within the time promised. Our only complaint is that the workers did not clean up very well. But overall, we’re satisfied and we’ll use them again."

FAQs for architectural service projects in Diamond Bar, CA

While you might think that architects only draw blueprints for buildings, they are much more involved in the overall construction process than you might realize. While they aren’t the ones swinging the hammers, architects do the following: 

  • Communicate with the homeowner on the project request, including assistance when exact plans aren’t known

  • Develop computer-aided models and blueprints of the requested design

  • Ensure that the design incorporates form, function, and safety features

  • Provide the contractor with the agreed-upon design

  • Supervise the general contractor and any subcontractors throughout the project

  • Communicate any needed changes to the project with the homeowner and draw new plans accordingly

Before settling on and hiring an architect, it’s beneficial to you as a homeowner to ask some questions to familiarize yourself with their work. After all, you wouldn’t want to spend time and resources on a professional that doesn’t specialize in exactly what you want in a house. Some questions to ask your architect include: 

  • How do you charge for services? Is it on an hourly basis, based on square footage, or based on project size?

  • How do we work together to stay on budget for this project?

  • Do you anticipate any future challenges with this project? How are these communicated?

  • What is your project management style? If you are not handling the day-to-day details, who is my point of contact? 

  • Can I see previous similar projects that you’ve completed?

  • Do you have any specialty experience, like working on historic homes or using sustainable building materials?

The average cost to hire an architect for your home project ranges between $2,200 and $10,500. However, depending on location and project type, you might end up paying as little as $600 or as much as $45,000 or more. For example, the average cost of hiring an architect in North Carolina is between $1,800 and $2,000, but in California, that price tag jumps to $3,600 to $15,200

The price you pay for your architect also depends on their experience level. For example, a principal architect, the firm's owner, typically charges $150 to $250 per hour. However, an intern architect with three to five years of experience usually only charges $45 per hour. 

After you’ve spoken with your contractor and agreed on a project, they’ll draw up blueprints, or plans, that the construction crew will use. The blueprint process can take between four and six months to complete. While this can seem like a long time, remember that the architect must communicate with your municipality to determine codes, communicate with you as the homeowner with any changes or adjustments, and coordinate with the construction crew. 

If you simply remodel your home or add an addition, the time to draw up the plans will be shorter since fewer permits and surveys are required. Even still, it’s best to plan for a few months for the architect to complete this part of the project.

Knowing if you need an architect for your project can be tricky, especially if you've never worked with one before. In general, small remodeling projects like replacing fixtures typically don't require the expertise of an architect. However, larger projects, like moving walls or adding an addition to your home, should include an architect to ensure the project is structurally sound.
