What L&L Builders does
L&L Builders is a commercial general contractor and construction manager headquartered in Sioux City, Iowa, serving the Siouxland region (Iowa, South Dakota, and Nebraska) since 1960. Founded by Larry Book and his brother Lonny as a masonry contracting business, the firm evolved into a full-service general contractor offering general contracting, construction management, estimation, project management, maintenance agreements, and in-house trade services including excavation, concrete, framing, and finish carpentry. Its project portfolio spans healthcare facilities (Mercy One, Floyd Valley, Horn Memorial, Rosecrance/Jackson Recovery), K-12 education (Kingsley-Pierson, Spalding Elementary), government and military installations (185th Air Guard Refueling Wing, Siouxland Aviation Training Center, South Sioux City Fire Station, IDA County Courthouse, Siouxland Expo Center), commercial clients (FedEx, K&K Mobile Storage, Oracle Aviation), civic buildings (Sioux City Convention Center), and historical renovations.
At the beginning of 2025, L&L Builders was acquired by Story Construction Co., a 100% employee-owned general contractor, construction manager, and design-builder headquartered in Ames, Iowa. L&L Builders now operates as a division of Story Construction Co., retaining its brand, dedicated local team (Joel Jarman as Division General Manager, Jim Mauer as Operations Manager, Evan Palsma as Senior Project Manager, TJ Wilcke as Preconstruction Manager, and Chris Stamm as Project Manager), and Siouxland market focus, while gaining access to the parent's preconstruction, operational, and capital resources including an ESOP. Revenue is generated on a project-by-project basis through competitive bidding and negotiated contracts across healthcare, K-12 education, government, commercial, industrial, warehouse, retail, and historical renovation market sectors; pricing is per-project and not publicly disclosed. Go-to-market is direct, relationship-driven enterprise field sales supported by a website (llbuilders.com), phone, and email contact channels.
