Founded in 1985, by Seattle architect Barbara Pickens and Eastside designer Ben Mulder, 4D Architects is noted for exceptional creativity and commitment to quality design. Our projects have been recognized with many regional and national awards.

While we’re big on quality, we’ve kept our firm small and our principals are personally involved in every project. You’ll find that we are good listeners and foster a friendly and relaxed way of working together.

We offer a full range of services that we can tailor to the needs of your project including: site selection and planning, feasibility analysis, building design, interior detailing, permit preparation and submittal, lighting design, bidding and construction documents, and construction observation and cost auditing.

We design effective buildings that are appropriate to the land form, paying close attention to your goals and working with you to consider design choices that are both cost-effective and sustainable in terms of energy and resources.

Our designs reflect the ecosystems and culture of the Pacific Northwest and no one knows the lay of the land better. We are experts in land use and environmentally critical areas (ECAs); we embrace the challenges and opportunities of difficult sites!

Our design expertise is enhanced by our extensive knowledge of building and municipal codes, as well as our accessibility and follow through during the construction phase.

4D Architects’ commitment to quality and excellence in producing unique designs and comprehensive construction documents is further illustrated by the high level of satisfaction expressed by our contractor and homeowner clients. We appreciate that so much of our work comes from referrals and repeat clients.

Your firm and team have put together some very good plans of high quality as far as structural and code review is concerned. It is a pleasure to review your work.
