We offer both structural and MEP design services to commercial, industrial and residential projects. Including:

Working from home is a new trend. Many have seen the benefits it offers while others are drawn to it by necessity. Having a dedicated place for work greatly improves concentration and work productivity.
A mixed-use building combines several functions into one structure. For instance, parts of a building may be devoted to hotel rooms while other parts are used for residential units and commercial services.
S3DA Design has experienced engineers who design to meet those goals, using the latest technology, and years of experience. Some of our Title 24 services include Title 24 calculation, remodeling lighting, Title -24 envelope, and Title 24 mechanical.
Solar power is increasingly popular, particularly in California which has made solar power mandatory for newly designed homes as part of Title 24, Part 6. Solar power reduces your energy bills…
