Founded in 2016, Stoneweg US is an opportunistic real estate investment firm with a nationwide platform focused on the acquisition and development of multifamily assets. We seek to deliver attractive, risk-adjusted returns to our investors by identifying market opportunities and optimizing asset performance, all while improving the resident experience through a variety of value-add strategies. Through our affiliation with Stoneweg SA, a Swiss-based real estate company with over $3 billion in assets under management, Stoneweg US serves as the exclusive US investment manager of Varia US Properties AG, a Swiss publicly traded multifamily real estate fund (SIX Swiss Exchange ticker: VARN). Stoneweg US also partners with US and international equity investors to acquire and develop multifamily assets in markets with strong population growth and positive trending economic conditions.




We approach investing with a commitment to excellence and strive to be best of class in all facets of our business.  We set aggressive yet attainable investment hurdles and seek to exceed these goals through detailed execution of our business plans and creative solutions to issues that may arise.


Our priority is to make a positive impact on everyone associated with our business and create value for all stakeholders through our disciplined investment approach that integrates social responsibility and environmental sustainability.  By efficiently developing and repositioning multifamily projects we serve an important social need and reduce our environmental footprint.


We strive to create value for our communities and their residents, as well as for our investors who make the opportunity possible.  We create value by identifying assets in high growth markets, aggressively negotiating purchase and debt terms and relentlessly executing our repositioning strategy across our portfolio.

At Stoneweg US, environmental sustainability plays a key factor in creating the best apartment communities for our residents.  Stoneweg US is committed to implementing sustainable practices that are pragmatic and achievable. We have successfully reduced our environmental footprint by repositioning older multifamily assets (rather than demolishing and rebuilding) and by developing new high-performance multifamily projects with a focus on reducing waste, energy and water use.


Given that many multifamily communities are older and are less energy efficient or have fewer sustainability features, there is a prime opportunity to improve sustainability and add value to our assets. Our water and energy conservation programs have significantly increased the environmental efficiency of our assets, while improving our residents’ quality of life and maximizing returns for our investors. In addition to reducing utility consumption, Stoneweg US is also focused on waste reduction. Those strategies include recycling programs at most properties in the Stoneweg US portfolio.

The Stoneweg US environmental sustainability goals are to:

  • Reduce current water consumption 15% by 2022

  • Reduce current energy consumption 20% by 2022

  • Invest in clean and renewable energy generation technologies, reducing emissions

  • Invest in green technologies that reduce energy and water use
