Portland Design Exploration is the development side of Plan Design Xplore. After years of helping make other people’s projects successful, partners Miles Sisk and Jonathan Konkol decided to bring their combined expertise in real estate finance, property management, architecture, land use planning, urban design, politics and market analysis to bear on the task of creating unique, small scale urban development projects.

In addition to developing projects of our own, we offer consulting and fee developer services.
