IsoShell

What IsoShell does

IsoShell is a privately held Hungarian professional services firm founded in 2012 that designs energy-efficient residential buildings using ICF (Insulated Concrete Form) construction technology. The firm's core offering is integrated, multi-discipline building design: architectural planning, structural engineering, mechanical/HVAC design, and electrical engineering are produced in parallel under a single coordinated workflow and delivered as permit-ready documentation, including an itemized cost estimate. The target customer is Hungarian families and small developers planning custom single-family homes or low-rise multi-unit residential buildings, with energy classifications of A+ or passive house as the design standard.

The underlying technology is the ICF system itself: expanded polystyrene formwork blocks are assembled on-site and filled with liquid concrete, and the formwork remains in place as a continuous thermal envelope around a monolithic reinforced concrete structural core. This produces a wall assembly with no thermal bridges at floor slabs, lintels, or corners, while mechanical and electrical conduits are routed through the insulation layer rather than the structural concrete. IsoShell's claimed differentiator is the integration of all engineering disciplines from the first sketch, intended to eliminate the miscommunication between architects and mechanical engineers that is typical of Hungarian residential construction.

IsoShell operates a direct-to-consumer model in which prospective customers book an obligation-free consultation via the company website, phone, or email and then progress through a four-step engagement (preparation and survey, concept and sketch design, engineering optimization, permitting and documentation). Revenue is generated through professional design service fees tied to the delivery of permit-ready plans and itemized cost estimates; pricing is not publicly disclosed. The firm serves only the domestic Hungarian market, has 1-10 employees, has not raised outside funding, and relies on a single minor partnership with Euromarknet for website and digital support.
