CUSTOM HOMES

At ST+B Engineering, we bring extensive expertise and a deep passion for designing mechanical and plumbing systems that elevate custom homes to the next level. Our team, including industry veterans like Brandon Chalk, has built a reputation for crafting high-end, energy-efficient systems tailored to the unique needs of each residence.

From large-scale new construction to finely tuned renovations, ST+B designs HVAC systems, air handling units, chillers, and plumbing infrastructure that meet the most demanding architectural and performance standards. We specialize in complex, custom residential projects that require more than off-the-shelf solutions. Our work is personalized, precise, and always pushing the envelope of what’s possible in home comfort and sustainability.

We work hand in hand with architects, interior designers, builders, and owners to ensure every mechanical and plumbing system integrates seamlessly into the home’s design. Our coordination process is built on clear communication and thorough attention to detail, helping us deliver exceptional performance without compromising aesthetics.

Energy efficiency and sustainability are at the core of our design philosophy. Whether it’s geothermal integration, high-efficiency boiler systems, or advanced control strategies, ST+B brings innovative, environmentally conscious solutions that reduce long-term energy use and enhance homeowner comfort.

With ST+B Engineering, you're not just getting a consultant. You're getting a dedicated partner committed to making your custom home as smart, efficient, and future-ready as possible. Let us help you bring your vision to life with mechanical and plumbing systems that are as thoughtful and refined as the home itself.

VALIDATION FROM CLIENTS

“ST+B Engineering has always been engaged, attentive, and a true team player on our projects. Whether it’s short-notice requests or long-term coordination, their team consistently shows up and plays a key role in project success.

On many of these high-end homes, there are 10 to 30 consultants involved, and it takes a strong mechanical engineering team to anticipate problems and coordinate clearly with the rest of the design group. ST+B consistently delivers on that front. They are professional, proactive, and always a pleasure to work with. I can’t say enough good things about the entire team.”

Steve Hansen

Owner, Hansen Construction

“ST+B Engineering brings a unique combination of technical expertise and great energy to every project. Their persistent good humor, responsiveness, and dedication to quality make them a pleasure to work with.

Whether you're a homeowner or architect, you’ll appreciate how levelheaded and solutions-oriented they are. I’ve worked with many engineering teams over the past 25 years, and ST+B stands out for their problem-solving skills and professionalism. I highly recommend them for any high-end residential or commercial project.”

 “Brandon - Just wanted to express the enjoyment derived from working with you! The experience, your positive attitude, and the fun you bring to the project are appreciated. The perception often arises that our work is inherently negative, as we are consistently addressing and identifying issues. Nevertheless, this message is intended to focus on positivity and express gratitude.”

“Thank you for all you do.”

 “I first worked with the Brandon Chalk and the ST+B team around 2010 on a large custom residence for a high-profile client at the base of Ajax in Aspen. From the start, they were capable, thoughtful, and easy to work with. The team approaches every challenge with a creative mindset and offers out-of-the-box solutions to complex problems.

Their thoroughness, professionalism, and cheerful attitude are a rare combination in the industry. I wouldn’t hesitate to bring them onto any residential project needing top-tier MEP expertise.”
