WHAT IS A BARN?
Traditionally, a barn housed livestock, grain, and equipment. Today, the definition has expanded.
At Cascadia Barn Designs, a barn may be:
- A modern barndominium
- A pole barn workshop
- A custom home or ADU
- A man cave or she shed
- A rural outbuilding or storage structure
We design architecturally grounded buildings for both rural and urban settings, expanding the traditional barn into something modern, refined, and highly functional.
OUR PHILOSOPHY
A BOUTIQUE APPROACH TO AN ARCHITECTURAL PLAN CATOLOGUE
BESPOKE
“be-spoke (bi-spok’), past tense and alternative past participle of bespeak. adj. |British|,
1. ordered in advance. 2. made to special order; custom-made.”
We recognize that one size may not fit all. Many of our designs have been built, some have not. We believe that all of our designs have broad appeal but understand that our customers are individuals with unique situations and requirements.
This means that at times it will be necessary to customize a given design to create a truly bespoke building, one that fits an individual Owner’s unique set of circumstances. Thus our shop is literally a boutique where one-of-a-kind buildings are created.
