Multifamily housing refers to a building that contains more than one dwelling unit, and they are continuously gaining popularity especially because of housing shortage; such buildings enable more homes in dense municipalities.
Our structural calculation follows local building codes, therefore not only ensures you can get a permit but also consider value engineering to cut down actual construction costs.
Over the years, your housing requirements change. Home remodeling allows you to make better use of your space and adapt to those changing needs.
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.
Warehouse design is a specialty of S3DA Design, as such projects often require both structural as well as Mechanical, Electrical, and Plumbing (MEP) designs, particularly for HVAC systems.
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.
Restaurants differ from other kinds of buildings because of the importance of their kitchen. A kitchen must be safe, competent, easy to maintain, and functional.
ADUs are tiny homes, mostly built for the purpose of renting to family members at lower-than-market rates. They offer an effective option to increase the value and space of your home.
Some of our HVAC services include mechanical drafting and design, mechanical detailing, 3D REVIT modeling, schematic heating, and cooling system design…
An accurate electrical design plan is crucial to accurately measure the energy usage of each component in the building, allowing to optimize for maximum efficiency.
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…
