Transforming Construction with Custom, Collaborative Solutions
STO Building Group

Ever imagined the simple act of building LEGO sets with siblings in childhood could manifest into a booming business venture?

STO Building Group (STOBG) brings this vision to life, operating collaboratively to provide innovative solutions for virtually any construction, renovation, or repositioning project. This privately owned family of elite builders functions with a shared network of resources, including real-time data, trade relationships, and buying power, while remaining true to their individual, distinct business models. The result? Clients receive personalized service from local experts alongside the strength and support of a global network.
Since its rebranding from Structure Tone Organization to STOBG in 2017, the company has earned a solid reputation as a leader in construction management. Its diverse portfolio of services includes site selection, design reviews, aesthetic enhancements, and major building infrastructure upgrades. These services are designed to maximize value, enhance existing assets, and bring innovative solutions to construction projects. From building repositioning to site evaluation, its team of seasoned professionals leverages technology and expertise to optimize value and revitalize existing assets.

In addition, the company’s commitment to safety, innovation, quality, compliance, and environmental, social, and governance (ESG) principles distinguishes it in an increasingly complex industry. Focusing on modernizing and transforming the building environment, STOBG tailors its solutions and services to address the needs of various clients while remaining uncompromising on excellence.

Recognizing the importance of determining whether a building can support a client’s vision, STOBG adopts a collaborative approach in evaluating each prospective space. The construction, design, engineering teams, facility staff, real estate brokers, and consultants assess the quality of existing structures to determine if the facility aligns with the client’s requirements. The company also offers commissioning services that uphold the highest quality standards in construction while validating that the built environment is constructed according to the plan and functions as intended.

As construction managers, we help clients bring their vision to life, whether it involves transforming landmark buildings in London or constructing commercial high-rises in New York City.

“As construction managers, we help clients bring their vision to life, whether it involves transforming landmark buildings in London or constructing commercial high-rises in New York City,” says James K. Donaghy, Executive Chairman.

Before the construction process begins, many factors, including labor, materials, equipment, and logistics, require careful consideration. Through a vast portfolio of preconstruction services, STOBG carefully evaluates these factors, integrating them into a cohesive plan aligned with the project’s budget, schedule, and design goals. Coupled with a deep focus on innovation, it continuously explores cutting-edge technologies to improve productivity and efficiency significantly.

Once the project is completed and the building occupied, the company’s facilities construction services (FCS) division focuses on managing capital projects, streamlining processes, overcoming challenges, and delivering exceptional value to its customers. By collaborating with them through its global client services group division, STOBG manages construction projects across diverse portfolios worldwide.

Its commitment to sustainability and wellness further drives STOBG to provide high-performance, eco-friendly solutions that reduce carbon footprints while enhancing employee wellbeing. Mass timber construction offers a fast, cost-effective, and sustainable alternative to traditional materials like concrete and steel, contributing to structural efficiency and environmental preservation.

This dedication to excellence fuels the company’s efforts to ensure a legacy of innovation and transformation within the construction industry. Through continuous investments in its people, processes, and community, STOBG is building more than just structures—it is actively shaping a better, more resilient future for future generations.
