Midland is an architecture and interior design firm specializing in enduring regional architecture delivered collaboratively to residential and commercial clients.  We are equally at home in the open green spaces of southwestern Pennsylvania and southeastern Ohio, as we are in its dense older cities and towns.  The unique character of this region, neither Midwest nor East, inspired our name and our mission: Midland.  We strive to provide design services individually tailored to each client, and to craft thoughtful solutions that address their needs, mindful of their budget and schedule. 

Matt Diersen, AIA


While studying at the University of Cincinnati, Matt would regularly engage in the “Pittsburgh is not a Midwestern city” debate, which got him thinking about the question of just where exactly it was. 

The native Pittsburgher returned in 2003, and refined his skills with several leading Pittsburgh firms. His professional experience ranges from small renovations and additions, to homes, offices, restaurants, retail spaces, and multi-unit residential, both adaptive reuse and new construction.  He is especially proud of the work he's been able to contribute to the current revitalization of Pittsburgh's city neighborhoods, notably Downtown, East Liberty, and Lawrenceville. 

He enjoys applying his problem-solving designer's eye and experience to difficult construction details, onerous existing structures, and challenging building code compliance. Solving easy problems is far less rewarding. 

He lives in the neighborhood of Morningside in Pittsburgh. 

Greg Dutton


Raised in the construction industry, Greg went on to study architecture at Miami University.  It was through his participation in the school's Over-the-Rhine Design-Build Program - a studio devoted to renovating structures in blighted communities - that he fostered his love for participating in all phases of the building process.  It's a practice that he has carried into his professional career; serving as designer, developer, and contractor on projects throughout Western Pennsylvania and Eastern Ohio.  What he enjoys most is taking a project from the early beginning stages of napkin sketches and inspiration photos and developing it along all points to construction completion.

His professional experience spans residential and commercial projects in both rural communities and urban neighborhoods.  Having grown up on a farm, and having spent his adult life living in cities, Greg seeks out working in both contexts.  

He lives in the neighborhood of Olde Towne East in Columbus.
