LA Creative Design - Large ADU project

LA Creative Design

(9 reviews)

LA Creative Design designed a garage addition and retaining wall for my home. Ben, Karthik, and…read moreMarmar were professional, pleasant to work with, and I felt the price for the design and structural analysis was very reasonable. Our garage construction is now more than half complete, and the design drawings have been accurate and have not required revisions or corrections during construction, which I appreciate. The main drawback was the timeline. It took quite a bit longer to get the final drawings completed than LA Creative Design had indicated when we hired them, and that delay affected my overall experience. Overall, I appreciated the quality of the design work and the reasonable pricing, but the extended timeline was a downside.

We hired LA Creative Design to produce the structural and engineering plans for our ADU and home…read moreexpansion in Los Angeles. From the beginning, the project and design engineers listened carefully to our ideas and respected our constraints, especially our goal of making sure the project didn't reduce our green space. They also offered suggestions that helped improve our original vision. Throughout the process, they took the time to meet with us several times and gave us the flexibility to make adjustments whenever we needed to. That made the design process feel collaborative rather than rigid. The plans they produced were detailed and easy for our builders to follow. Communication was consistent, and whenever questions about structural details came up, they were quick to respond. When plan check comments came back from the city, revisions were handled promptly and without issue. ADU projects can be complicated, but the engineering portion of our project was handled professionally. We would recommend LA Creative Design to homeowners or developers looking for engineering and structural plans for an ADU or home expansion.

The project involved a complex structural modification: connecting two rooms on separate floors via a spiral staircase, which required cutting a 5'x5' opening in the second-story floor. Because this opening was directly connected to a Juliet balcony outside from a 9'x 6' sliding glass door, we were concerned about preventing a collapse when cutting the joists. We are deeply impressed by the expertise, time, effort, and dedication that Kobe and his team devoted to this challenge. They opened up ceilings and walls, calculated loads, worked tirelessly to replace the necessary supporting joists and secure the Juliet balcony. Furthermore, they followed through diligently with the LADBS to ensure our plans were approved. Throughout the entire journey, Kobe team was knowledgeable, honest, and attentive. We are extremely thrilled with the results and grateful for their expertise.

For starters this outfit actually answers their phone, which is a good start. I quickly made an…read moreappointment to which they showed up to on time.
