10 December 2025

Walter Herz, in cooperation with Syrena Invest, has finalized another land transaction for a residential project in Warsaw. The recently completed process concerns the development at Głębocka Street in the Białołęka district of Warsaw, which will include 79 apartments and an underground garage. The project covers approximately 4,300 usable floor area (PUM). This transaction represents the next stage in the strengthening collaboration between the companies, following a previous land acquisition for a project at 29 Siennicka Street in Warsaw.

– We value Walter Herz’s advisory services and comprehensive support in investment processes, which often require a high pace of action, strong commitment, and the ability to develop effective solutions at various stages. Another transaction in Warsaw confirms that together we are able to successfully identify and close valuable opportunities in the residential segment – says Marianelly Hernandez Reyna, General Director at Syrena Invest.

Walter Herz’s scope of work included comprehensive consulting services throughout the entire acquisition process, from the analysis and project preparation phase, through negotiation management, to the finalization of the transaction. The teams involved in the project were responsible, among other things, for a thorough assessment of the investment’s potential and for developing optimal conditions for both parties.

– This was a demanding, multi-stage transaction, successfully completed thanks to thorough analysis, consistency in negotiations, and a cooperative partnership between the parties. The obtained building permit increases the project’s value and allows for faster implementation of the investment – says Damian Karkosiński from Walter Herz. – Following the successful land transaction at 29 Siennicka Street, this is another joint project that confirms the quality of our business relationship. We are very pleased to continue our cooperation with Syrena Invest and are glad to support the development of their project portfolio in the Warsaw residential market, where Białołęka remains one of the most promising locations - adds Damian Karkosiński.
