Welcome to Stream Real Estate Development & Investment

Stream Real Estate creates quality, contemporary developments in the most sought after markets, while pushing the envelope on sustainability.

About Us


Stream Real Estate started with the premise that we would push the envelope with sustainability and environmental responsibility, while maintaining financial viability.

Sustainable Apartment Living not only means every Stream Real Estate property is LEED® certified, it means they are designed for today’s lifestyle.

Stream Real Estate led the launch of Urban Housing Ventures (UHV) in 2020 as part of their commitment to providing workforce affordable rents to working-class families. For more information, visit www.urbanhousingventures.com



Stream is a founding partner with Forterra, a local leader in land conservation. Together we created the Evergreen Carbon Capture project that enlists individuals and organizations to help sustain our magnificent region by planting trees in parks and along streams. We inspire others by doing, and we’re proud to say that since the program’s inception, Stream has been the largest contributor to carbon offset. We’ve planted more than 2600 trees in Western Washington since 2012.

Carbon offset is just one part of the solution to continue our mission to promote sustainable living – we are also part of Seattle City Lights Green Up program. Our participation in the Green Up program helps generate a market for renewable energy in the Pacific Northwest.

All Stream properties are also LEED® certified and we continually strive to go beyond carbon neutral to make a positive and lasting impact.

Sustainable Development

Sustainable Apartment Living is what we are about.

We believe we need to be smart about our resources and conservation. We aspire to make each apartment building a little more green than the last one, better for our tenants and better for the environment.

Air-to-Water Heat Pumps

The use of reverse cycle chillers air-to-water heat pumps for heating all of the hot water for our buildings. This system uses a highly efficient heat exchanger to transfer ambient heat in the air of the garage level to the hot water supply system. We anticipate that this device will allow the projects to provide hot water to the tenants using primarily on-site energy generation.

Electrical power utilized in our building projects is purchased through Seattle City Light, a regional utility, that relies on clean energy production. In addition, we are seeking to acquire electricity from alternative energy sources (primarily wind generated) for our real estate projects, from a Seattle City Light program.

ORIG water drop iconReclaimed Storm Water Means Happier Salmon

Systems to reclaim storm water through vegetation planters allow gradual release of storm water from the building site into the city’s combined sewer system. Easing storm water runoff, helps mitigate its effect on city infrastructure and ultimately on Lake Union and Puget Sound. This is vital in Seattle where the city’s surrounding bodies of water are vulnerable when excessive storm water is combined too quickly with sanitary systems.

Our buildings provide a full complement of recycling bins and recycling services conveniently located in the building. Our signage encourages tenants to appropriately conserve resources and properly dispose of materials and to recycle to reduce waste.

High Walk-Scores Mean Less Driving

When you walk more, you minimize the impact of private transportation on the environment. Stream Real Estate Development and Investment, intentionally develops buildings within close proximity of public services such as bus lines, trolleys, bike routes and corporate transportation.

white power save iconStandard Practices

  • Low Flow Water Fixtures
  • Energy Star appliances
  • Designs that allow passive cooling of most living spaces
  • No or Low VOC (volatile organic compounds) paints, sealants, adhesives and carpet systems anywhere in the building.
  • Highly reflective roofing minimizes the heat island effect associated with dark roofs. We also reduce heat island effect by enclosing 100% of the parking within the building. The heat island effect is responsible for raising temperatures several degrees higher in urban areas compared to that of non-urban areas.
  • Landscaping is based on plant compatibility with local rainfall patterns thus reducing the need for landscape irrigation.
  • Refrigerants in the mechanical systems that are less damaging to the ozone and contribute less to global warming than typical refrigerants.
  • Recycling of 75% of construction waste generated onsite during development and construction
