LSE Builders Group

What LSE Builders Group does

LSE Builders Group is a privately held, founder-owned General Contracting and Construction Management firm headquartered at 1120 Boston Avenue in Longmont, Colorado. Founded in 2015 by Steven South and operating with approximately ten team members, the firm delivers ground-up construction, core and shell buildouts, renovations, tenant improvements, and multi-family projects across seven verticals: Educational & Institutional, Light Industrial, Residential & Multifamily, Religious Meeting Spaces, Shopping Centers & Retail, Medical & Health Related, and Athletic Facilities. Its geographic footprint is the Northern Colorado Front Range, spanning Westminster to Wellington and Boulder to Greeley.

The company offers four delivery models (Design/Build, Design/Bid/Build, CMGC, and On Call/Standard Order contracting) and executes work for a mix of institutional and private clients, including standing order relationships with USPS, Boulder Valley and St. Vrain Valley School Districts, the University of Colorado at Boulder, RTD, and Ball Aerospace. It carries Design/Build partnerships with Asher Architects + Engineers, ArcWest Architects, and Skyhook Designs, and maintains an ongoing channel relationship with NewMark Merrill for shopping center capital programs. The firm operates LSE Residential as a dedicated sub-brand for custom residential and boutique multifamily work, applying commercial-grade process discipline (safety, quality, schedule, cost) developed since 2022. Revenue is generated project-by-project through budgetary proposals and bids; pricing is quote-based and not publicly disclosed, and the company self-performs limited scopes (saw cutting, finish carpentry, millwork) supported by its 2024 production workshop expansion.

Direct peers

• Haselden Construction: Denver-based general contractor of comparable size delivering commercial, healthcare, higher education, and tenant improvement projects across Colorado. Highly comparable to LSE in vertical mix (education, healthcare, retail), project delivery models, and Colorado front range geography.
• Saunders Construction: Centennial, Colorado-based general contractor serving commercial, healthcare, education, and multifamily markets across the Front Range. Similar full-service GC positioning, design-build delivery model, and Colorado institutional client base to LSE.
• Mark Young Construction: Denver-area general contractor with comparable size and scope delivering commercial, healthcare, education, and tenant improvement projects across Colorado. Operates in similar delivery models and competes for overlapping front range institutional clients.
• Bryan Construction: Colorado Springs-based general contractor delivering commercial, healthcare, education, and federal projects across Colorado and the Rocky Mountain region. Comparable full-service GC offering with similar institutional client mix to LSE.
• GH Phipps Construction Companies: Denver and Wyoming-based general contractor delivering commercial, healthcare, education, and industrial projects across the Rocky Mountain region. Similar size, vertical mix, and self-perform trade capabilities as LSE, and competes for the same Northern Colorado institutional work.
• Catamount Constructors: Denver-based commercial general contractor delivering tenant improvements, healthcare, education, and specialty projects across Colorado. Directly comparable size and vertical alignment to LSE, particularly in tenant improvement and commercial interiors work.

Broad incumbents

• Adolfson & Peterson Construction: Larger regional GC headquartered in Minnesota with significant Colorado operations serving commercial, education, healthcare, and multifamily markets. Broader geographic footprint and greater bonding capacity than LSE but directly competes for the same institutional and commercial work in Colorado.
• Hensel Phelps: Large employee-owned GC headquartered in Greeley, Colorado, delivering aviation, healthcare, education, commercial, and federal projects nationally. Same Northern Colorado home base as LSE and overlap on education and institutional work, but at significantly larger scale and bonding capacity.

Regional players

• Oakwood Homes: Denver-based homebuilder focused on new construction residential communities, townhomes, and move-up housing across the Colorado Front Range. Comparable to the LSE Residential division for residential construction activity in the same regional market, though focused on production rather than custom work.

Others

• Asher Architects + Engineers: Colorado architecture and engineering firm that is a recurring design-build partner of LSE. Adjacent rather than competitive; included as an ecosystem participant that drives joint project flow into LSE and illustrates the design-build delivery approach.
