Our expertise is in our process.

Barley|Pfeiffer Architecture’s core strength is designing high performance buildings that are less expensive to operate & maintain, are healthier to be in, incorporate balanced lighting that reduce eye strain, and are comfortable to live and to work in.

 We engage in a collaborative “Comprehensive Design” approach that involves us in all aspects of a project:  from programming to master-planning, interior design, green building strategies analysis, mechanical systems design, lighting design and construction estimating and review. Utilizing this collaborative approach, our scope of work can be tailored to fit the budget and needs of each one of our clients.

 While we do not have a set “design style”, our projects are designed to “live well” with the site; paying close attention to its micro-climate and setting – and blending that cohesively with our client’s tastes, goals and aspirations.  All By Design!
