Mechanical Electrical & Plumbing Design Services
Our structural and MEP design services emphasize cross-disciplinary collaboration with a variety of construction and procurement partners. We specialize in sustainable design, adhering to local codes, and cost-effective solutions for the residential, commercial, and industrial sectors.
Electrical Design
Electrical design is the beating heart of any modern building. A haphazard electrical design can lead to wasted energy and high maintenance costs. Reliable systems is about more than just installing equipment, it’s about planning and strategic optimization. We’ll work collectively to customize electrical schematics, power plans, site plans, panel schedules, distribution panels, and more.
Plumbing Design
Plumbing design is an essential part of any infrastructure, responsible for both delivering water and removing waste. But designing an efficient system is about more than just getting water where it needs to go- it’s about optimizing every aspect to save energy, water, and money.
We design systems that provide just the right amount of flow and pressure, while minimizing pumping costs and maintenance. Our engineers develop plumbing designs that adhere to California design codes while optimized for maximum efficiency.

HVAC
The HVAC system is the backbone of any building, delivering needed comfort for occupants. However, HVAC systems can be a huge drain on your overhead, especially if they’re not designed for maximum efficiency.
Our licensed engineers won’t just create HVAC designs that maximize efficiency, we’ll also ensure they meet building codes for hassle-free city approval. From floor plans to equipment specifications, we cover every step of the process. Our comprehensive HVAC services come complete with mechanical drafting and design, 3D REVIT modeling, schematic heating, cooling system design, and more.
Title 24 Compliance
In 2013, California initiated Title 24, a building energy efficiency standard that regulates how new and existing buildings maintain environmental and sustainable quality. Every building is constructed to optimize for more comfort, lower energy costs, and less carbon emissions.
S3DA Design meets these goals using cutting-edge technology and up-to-date practices. Some of our Title 24 services include calculation, remodeling lighting, Title 24 envelope and mechanical
Solar Design
Solar power is the future of energy, and for good reason-it reduces energy costs and carbon footprint. As of 2020, solar power is mandatory for new construction homes and multi-family dwellings up to three stories. But installing a solar power system can be daunting. We’re at the forefront of the ever-changing solar industry, delivering quality solutions in the renewable energy field. We’ll draft a cost-effective plan designed to meet your construction goals.
Fire Protection
Integrating fire protection is given for any infrastructure. We help map out a crucial schematic diagrams like smoke detection, sprinkler placement, fire alarms, and gas suppression systems.
Moreover, we determine accurate requirements, calculations, and appropriate testing routines. Through maximum efficiency and lower costs, we incorporate measures to prevent, circumvent, and minimize fire damage.

Frequently Asked Questions
1. How many sets of architectural designs do I need to build a house?
It depends on the complexity of the house, but in most cases, you will need roughly 5 to 8 sets. Those who will need design prints include:
- The owner
- The Contractor
- The Sub-contractors
- The Building Department
- The Mortgage Lender
- The Building Inspector
2. Can I design my own house without an architect?
Yes, you can. If you or your builder have a talent for design, a clear idea of what you want, and if you can create plans that meet your local building authorities, you can go ahead with designing your house.
3. How much does an architect charge for architectural home design?
Well, it depends on several factors such as the complexity of the project, the square area of the land, add-on services like extra revisions, project management services or any type of construction help. We recommend you get in touch with our experts for a better understanding.
4. Do architects charge for an initial consultation?
Different architects offer numerous services when it comes to initial meetings with potential clients. Many architectural design firms agree to a quick, one-off introduction free of charge to discuss the project, your budget and their ability to deliver.
