Our Reviews
Posted on Simon Abraham SchwartzTrustindex verifies that the original source of the review is Google. We partnered with Firas the engineer at Slim Design Consulting for a garage-to-ADU conversion for our home in Newport. The experience was solid all around. Firas was clear, responsive, and very in tune with what the city expects, which helped keep the project moving with no corrections. From an investor standpoint, that reliability matters. We appreciated how straightforward he is, from concept to completion. Very knowledgable and professional.Posted on Susan Andrea WilliamsTrustindex verifies that the original source of the review is Google. Our HOA hired Slim Design Consulting for our required SB326 balcony inspections and we are very glad we did. What felt like a stressful requirement turned into a smooth and straightforward process. The engineer, Firas, was thorough during the inspection and took the time to explain everything in a way that was easy to understand. The report was clear, detailed, and helped us plan the next steps and repairs without confusion. Communication was great from start to finish and everything was handled professionally....We would absolutely work with Slim Design Consulting again and highly recommend them for balcony inspections!!!Posted on Ismael BecerraTrustindex verifies that the original source of the review is Google.
