Our Expertise is in Our Process
Barley|Pfeiffer Architecture’s core strength is designing high-performance homes and buildings that are beautiful and timeless. Recognized for their attractive design, integrity, and ability to stand up to the elements – they are less expensive to own, operate, and maintain, are healthier to occupy, and are more comfortable to live and to work in.
Our “Comprehensive Design” approach means we engage in all aspects of a project from thoughtful initial project programming and site-planning, to award-winning interior design and kitchens, green building strategies and analysis, mechanical systems design, dramatic lighting design that doesn’t sacrifice practicality and comfort, as well as full construction administrative services.

Our scope of work can be tailored to fit the budget, schedule, and specific needs of our clients and their projects. We listen and are flexible. While we do not have a set style, our projects are designed to “live” particularly well with their site, paying close attention to the site’s micro-climate and setting – all while blending cohesively with our client’s tastes, goals and aspirations. Comprehensive Design blended seamlessly with Innovative Building Science!
Profile and History
Live well by doing well. Luxurious and healthy living combined with pragmatic environmental stewardship has been our focus for 35 plus years — and we have gotten pretty good at it!
We know that each site, building, and client is unique. By incorporating environmentally sound design strategies, our firm offers comfortable and healthy, yet reasonably priced living and working accommodations. Our homes and buildings are recognized for their intelligence, energy efficiency, and innovative utilization of space. Our approach will appeal particularly to those who intend to own their home or building for many years — to be passed on to the next generation, and possibly the one after that!
