Our experience selling across all asset classes in primary through gentrifying  markets gives us the network, knowledge, global reach and expertise to achieve optimal results for our customers and clients.

________________________ Broadening horizons


The success of the NYC-centric business led to a natural expansion when Atrium found itself advising on several investment transactions in Portugal from the acquisition of a rural vineyard, to industrial repositioning projects in Lisbon and continual single user investment transactions in between. Realizing the synergy with the Portugal market base, it was a natural expansion. Committed to Atrium's core philosophy the new Lisbon office has been greeted with excitement by American based and European investors alike looking to expand and successfully place money in Portugal.
