"Eran from ESL Designs helped us with ADU design, drawing and permit submittal. They are easy to communicate with and great to work with. Eran has a lot of knowledge of design ADU to meet our requirements. We had many phone calls, office visit and in site visits with Eran and his team before signing the contract. Everything was laid out clearly and Eran made sure I won’t have any surprises throughout the project. We had in person discussion with Eran to finalize the building set. Eran submitted and followed up with the city on permit review. Overall, good experience. Will recommend to my friends in the future for ADU design."

"Edward was able to take my basic idea for a porch design and elevate it to a level I couldn't have imagined initially. He was very communicative throughout the process and made the whole process a breeze."

Customers say: True professional

"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

FAQs for design and decorating projects in Diamond Bar, CA

Start by defining your goals and budget. Collect photos of rooms you love, jot down must-have features, and list what isn’t working in your current space. Share these details—and your target budget—during the first meeting. The clearer you are, the quicker a designer can translate your vision into a workable plan and keep costs in check.

Yes, working with an interior designer can help you save money. Designers prevent costly missteps, secure trade discounts on furniture and finishes, and coordinate the project so you don’t pay twice for the same work. Their upfront fee often pays for itself in avoided change orders, tighter timelines, and materials purchased at below-retail pricing.

A full interior design project wraps up in two to three months, on average, while a decorating job takes four to eight weeks. Timelines stretch if you add structural changes, custom millwork, or specialty materials, and unexpected shipping or permit delays can tack on extra days. Talk with your designer about project milestones and build in a little wiggle room.

Interview at least three pros whose portfolios match your style. Review their credentials and ask for references. During a face-to-face or virtual meeting, discuss your goals, budget, and timeline, and make sure their communication style and fee structure feel comfortable. The right designer combines technical know-how with a creative approach that clicks with you.
