BakerStreet I. – Unlocking Value Across the Full Real Estate Lifecycle

From tenant representation to disposal - Hungary’s largest office transaction in 2025
iO Partners supported BakerStreet I. throughout its real estate lifecycle – from representing E.ON in securing its new headquarters and overseeing the delivery of the building, through strengthening the lease profile, to advising Atenor on the successful disposal of the asset. By combining leasing, project management and capital markets expertise, iO Partners helped create a compelling institutional investment proposition and ultimately introduced a new investor to the Hungarian market.
A STRONG ASSET, POSITIONED FOR A SUCCESSFUL EXIT.
BakerStreet I. is a newly developed, institutional-quality office building in South Buda, providing approximately 16,600 sq m of modern office space and serving as the Hungarian headquarters of E.ON.
iO Partners’ involvement with the property began well before the investment sale. Having represented E.ON in securing its new headquarters and supported the delivery of the building, the team had an in-depth understanding of both the asset and the occupier.
Ahead of the disposal, iO Partners worked closely with Atenor and E.ON to further strengthen the investment profile of BakerStreet I., including the extension of the lease. This resulted in a long-term, secure income profile and created a highly attractive institutional investment proposition.
