Who We Are

Built to Raise the Standard

Modern Building Systems is a Colorado-based exterior construction firm serving homeowners throughout the Front Range. Our team brings together licensed contractors, structural engineers, and skilled masons to deliver exterior projects that are both technically sound and visually cohesive.

We don’t approach exterior work as isolated services. Instead, we look at the entire structure — how materials interact, how weather affects performance, and how design choices impact longevity. This integrated mindset allows us to deliver results that feel intentional, not pieced together.

What We Do

Complete Exterior Services, Thoughtfully Delivered

Our work spans the full exterior of the home, allowing us to manage complexity without compromise. By keeping services under one experienced team, we reduce friction, improve coordination, and deliver a cleaner overall result.

What People Say

Words from our clients

Josh and Wes turned our backyard into something we actually want to show off.

We had a general idea of what we wanted, but Josh immediately saw the bigger picture. He and Wes designed a deck that feels like it was always meant to be part of our home. The craftsmanship from the MBS team is unreal — clean lines, flawless finishes, and not a single detail overlooked. It’s become our favorite place to unwind, and every guest comments on how high-end it feels.

MBS understood our vision better than we could explain it.

We told Josh we wanted something modern and minimal, and he came back with a design that exceeded anything we imagined. Wes walked us through materials and layout options with so much patience and clarity. The final deck looks like it belongs in a luxury resort. The MBS crew was respectful, tidy, and incredibly skilled. We use the space every day now.

The quality is on another level — you can tell Josh and Wes take pride in their work.

We’ve worked with plenty of contractors over the years, but MBS is in a completely different league. Josh checked in constantly, Wes oversaw every detail, and their in-house team built a deck that feels rock-solid and beautifully finished. No subcontractors, no excuses — just real craftsmanship. It’s rare to find a company that cares this much.

Our outdoor space feels like a luxury retreat thanks to MBS.

Our old deck was small and dated. Josh and Wes redesigned the entire layout and gave us a space that feels intentional, modern, and incredibly comfortable. The materials they recommended were perfect for our home’s style. The MBS team worked with such precision — even our neighbors commented on how professional they were. We’ve already hosted more gatherings in the last month than we did all last year.

Josh helped us choose windows that completely transformed our home.

We replaced every window in the house, and the difference is unbelievable. Josh walked us through the design options, and Wes made sure the installation was flawless. The MBS team treated our home with so much respect — no mess, no rushing, just careful, detailed work. The natural light and clean lines make the whole place feel brand new.
