Neinor Homes, S.A. is one of Spain's largest residential real estate developers, operating primarily in the build-to-sell market. The company's business model spans the entire property development lifecycle, from strategic land acquisition and urban planning to commercialization and property handover, while typically outsourcing the physical construction of its projects. Neinor focuses on high-demand geographic areas across Spain, such as Madrid, Catalonia, Andalusia, the Basque Country, and the Balearic Islands. The company generates the vast majority of its revenue from its Development segment, which involves the promotion and sale of newly built residential units. In recent years, Neinor has diversified its operations by expanding into the build-to-rent (BTR) sector and third-party asset management, providing services for institutional co-investors and managing rental portfolios. The company has grown significantly through strategic acquisitions, including its merger with Quabit Inmobiliaria in 2021 and the acquisition of a controlling stake in rival developer Aedas Homes in late 2025, consolidating its leadership position in the structurally undersupplied Spanish housing market.
