Stoneweg & BGO to build €500M Spanish living platform

Stoneweg and BGO have formed a strategic joint venture to establish an institutional-grade living platform in Spain, mobilising a planned €500 million of capital. The move targets mounting demand for professionally managed, sustainable rental housing in core Spanish cities and aims to accelerate the country's underdeveloped private rented sector.

The partnership will convert existing projects and develop new purpose-built assets tailored to young professionals, mobile corporate workers and long-term renters seeking flexible, amenity-rich homes. The first asset to join the JV will be Bext Valdebebas, a recently completed complex offering 583 units and a package of shared facilities including gym, co-working areas, paddle courts and a pool—an asset that holds a BREEAM Excellent sustainability rating. The Valdebebas acquisition was financed by Aareal Bank and will seed the platform.

Javier López Galdos, Managing Director at BGO, said the firm sees significant runway in Spain owing to structural shortfalls in housing supply and evolving residential habits. He emphasised the partners’ plan to scale across segments and locations, bringing institutional standards to product design, services and operations. BGO manages approximately $89 billion of assets and will deploy its asset-management capabilities to operate and grow the JV.

For its part, Joaquin Castellví, Co-Founder and CIO of Stoneweg, framed the alliance as a landmark step to consolidate sector leadership in Spain. Stoneweg, which lists roughly €11 billion in assets under management, brings pipeline projects developed under its Bext Space brand, plus local development and capital markets expertise to the venture.

Market context strengthens the JV’s rationale: Spain’s institutional living stock remains modest compared with northern European peers, leaving room for professional investors to expand the build-to-rent (BTR) universe. Institutional investors across Europe have increasingly prioritised living assets for steady cashflows and long-term inflation hedges; in Spain, that trend is only now gathering momentum as regulatory clarity and product standards improve.

Operationally, the JV will focus on assets in well-connected urban districts, emphasise sustainability certifications, and integrate resident services to command premium occupancy and retention. The first-phase programme centres on repositioning and leasing Bext Valdebebas while advancing identified greenfield opportunities. The partners also flagged potential co-investment rounds with institutional limited partners as the platform scales.
