Under One Roof Construction LLC

What Under One Roof Construction LLC does

Under One Roof Construction LLC is a privately held, founder-owned general contracting firm established in 2009, headquartered in St. Charles, Illinois, with service coverage across Illinois and Wisconsin. The company operates two interconnected business lines. The Under One Roof construction arm delivers complete residential remodeling (kitchens, bathrooms, exteriors, custom builds) and mid-to-light commercial construction services, including new build-outs and second-generation builds for clients across fitness, healthcare, beauty, office, medical, restaurant, brewery, and manufacturing sectors. The Noir Holdings arm purchases neglected residential properties, renovates them internally using the affiliated construction company, and resells them to high-income buyers seeking modernized homes in premium suburban municipalities with strong schools and amenities.

The company makes money through three primary streams: (1) property resale profit from Noir Holdings's flipped inventory (with disclosed property purchase prices ranging from $285K to $614K and annualized ROI between 7.8% and 58.45%); (2) professional-services fees from residential remodeling projects, with detailed written bids following initial consultation; and (3) professional-services revenue from commercial build-outs for a roster of 12+ named clients such as Lifetime Athletic, Anytime Fitness, Jazzercise, Waxing the City, Phenix Salon Suites, Complete Nutrition, Oswego Brewery, Higgins Chiropractic, Cyl Tec, Master Brew, and The Kitchen Studio of Glen Ellyn. GTM is bifurcated: enterprise field sales for Noir targeting affluent second-/third-home buyers with cash or non-contingent financing, and direct-to-consumer engagement for construction services.

The competitive model hinges on vertical integration. By owning the general contracting capability, the company claims a 20-23% pricing discount versus comparable new construction, a 53% average value uplift from buy to sell, and consistent sales 19% above third-party appraisals. The firm is led by co-founders Shannon Mogilinski (CEO, 15 years of general contracting experience) and Michael Mogilinski (CFO, 25 years of real estate investing experience). There is no public revenue disclosure, no disclosed headcount, no venture or private-equity backing, and no evidence of AI/ML or proprietary software technology in the operation.

• Offerpad: Institutional iBuyer that purchases, renovates, and resells homes directly to consumers. Comparable end-to-end buy-renovate-sell model, though at much greater scale and with balance-sheet-funded acquisition rather than affiliate construction.

• Dreamstyle Bath & Kitchen: Regional home renovation specialist focused on kitchen, bath, and home exterior remodeling. Comparable scope of residential remodeling services and project-management-led delivery model.
• Re-Bath: National bathroom remodeling franchise with walk-in showers, custom tiling, and full bath renovation services. Directly comparable to Under One Roof's bathroom remodeling service module and residential remodeling GTM.
• Window World: National home exterior remodeling franchise focused on windows, doors, and siding installations. Comparable home exterior renovation service module and franchise-style regional operator structure.
• MainStreet Homes: Design-build residential firm offering custom home building and renovation services. Comparable vertically integrated residential construction model serving homeowners in select regional markets.

Regional players

• BLDG Partners: Commercial construction management firm specializing in retail, restaurant, healthcare, and fitness build-outs. Comparable commercial build-out scope and project management model, particularly for franchise rollouts that match Under One Roof's commercial client list.
