S5 Construction | 2015-2026

S5 Construction was built on a conviction: the person who draws the building should be willing to stand behind building it. Founded by architect Jeff Seabold as the construction affiliate of Seabold Architectural Studio, S5 delivered commercial and residential projects across the Jackson metro area for a decade, with the firm's principal holding both an architecture license and a Mississippi commercial general contractor license and serving as Architect of Record and General Contractor on the same programs.

That integration was not a marketing line; it was the operating model. Design decisions were priced as they were drawn. Life-cycle cost guided material selection. Preconstruction was forensic rather than optimistic, and the schedule was built by the people who would live with it. S5's work includes the award-winning renovation of Coalesce at 109 N. State Street, the recipient of the 2016 City of Jackson Historic Preservation Award and a State Historic Tax Credit project, as well as historic office restorations, high-performance homes, and multi-unit commercial programs.

S5 concluded active operations in 2026, as founder Jeff Seabold, FAIA, turned his focus to institutional leadership and his national service on the AIA Board of Directors. The company's record stands as delivered: buildings that were smart, sensible, straightforward, and seamless, and that will hold their value for generations.

Jeff Seabold, FAIA | Founder & President, S5 Construction (2015-2026)

Jeff Seabold founded S5 Construction in 2015 on an uncommon premise: that the architect who drew the building should be willing to build it. For a decade he held a Mississippi commercial general contractor license alongside his architecture license, and S5 delivered as General Contractor on projects where he also served as Architect of Record, running up to $8-10 million in annual integrated design-build volume as the construction arm of The Seabold Companies. That meant pricing design decisions as they were drawn, building schedules with the people who had to keep them, and answering for the finished building with no one else to point to.

The work ranged from award-winning historic renovation, including the Coalesce project at 109 N. State Street, recipient of the 2016 City of Jackson Historic Preservation Award, to high-performance homes, franchise prototypes delivered to fixed opening dates, and the executive headquarters of the regional operator whose portfolio S5 served for years.

Jeff is a Fellow of the American Institute of Architects, a distinction held by roughly three percent of AIA members, and serves as an At-Large Director on the AIA National Board of Directors (2026-2028). He is a past President of AIA Mississippi, a four-term President of the City of Jackson Historic Preservation Commission, and was the first architect in Mississippi to earn the LEED AP Homes designation, sustainability commitments that shaped how S5 built: efficient envelopes, honest materials, and buildings meant to hold their value for generations.

S5 concluded active operations in 2026 as Jeff's focus turned to institutional leadership and national service. He lives in Jackson's Fondren neighborhood with his son, Windsor, still cooks, still builds in his wood shop, and still believes the best guarantee in construction is the builder's name on the drawings.
