Built-In Shelving & Storage on San Juan Island

There is a difference between mounting a shelf and building storage, and this page is the second one. A single floating shelf, a closet rod, or a wire system out of a box is quick work and belongs with mounting and shelving. What I mean here is carpentry: a closet built out with real shelving and double hanging, a pantry sized to how you actually shop, a mudroom bench with hooks and boot storage, a wall of shop shelving that holds weight, or gear storage in an outbuilding that keeps rodents out of it.

Island houses generate a specific storage problem, and it comes from provisioning. When the nearest full run of errands involves a ferry, you buy in quantity. Households here keep more canned goods, more paper goods, more bulk staples, and more spare hardware than a mainland house of the same size, and most of these houses were not designed for that. The single most useful thing I build is deep, properly supported pantry shelving in a utility room or a garage — adjustable, sized for cases and #10 cans rather than for cereal boxes, with the bottom shelf up off the concrete.

The second is wet gear. Every house here has a pile of it: rain shells, boots, PFDs, crab pots, kayak paddles, chainsaw and fuel, a wheelbarrow, garden tools, and a dog towel. A mudroom or entry bench with hooks at two heights, a slatted or open shelf underneath so boots dry rather than sitting in their own water, and a bin cubby is a genuinely life-improving piece of carpentry in a climate with eight wet months. Slatted, not solid, is not a style choice — it is the difference between drying and mildewing.

Third is the garage, shop, or outbuilding, where the constraints get interesting. Rodents are a real and constant pressure out here, and a storage plan that ignores them fails. So: no cardboard boxes on the floor in an outbuilding, soft goods and fabric in sealed hard bins rather than on open shelves, food and seed in metal, and shelving that keeps everything up off the slab with an inspectable gap behind it rather than pushed tight to a wall where nothing can be seen. I build to leave those sight lines open on purpose.

Moisture drives the rest of the detail. Uninsulated garage and outbuilding walls and bare concrete slabs run damp for most of the winter here, and anything sitting hard against them will absorb it. I hold shelving off the wall with a cleat or a spacer to give an air gap, keep the lowest shelf several inches above a slab, and use plywood rather than particleboard or MDF anywhere near an unconditioned space, because MDF in a damp island garage swells into a sponge and never recovers. In a crawlspace-adjacent or unheated storage area I will use treated stock at any point of contact.

Inside the house, the common jobs are closet build-outs and built-in shelving in awkward spots. Island houses are full of awkward spots — knee walls under a roof pitch, a stair landing, a chimney chase, a dormer nook. Site-built shelving is the only thing that fits those, because nothing off a shelf is the right dimension. I build in plywood with a hardwood or painted face, scribe it to the wall so there is no gap in an out-of-square old house, and anchor everything into framing rather than into drywall. Every island cabin I have worked in is out of square somewhere, which is exactly why factory units look wrong in them.

Load capacity is the part people underestimate. Book shelving and pantry shelving carry real weight, and a 3/4-inch shelf over 36 inches will sag under books within a year unless it has a front edge stiffener or a center support. I size the span to the load rather than to what looks right, and I will tell you if what you are picturing needs an extra vertical. That is a boring conversation that saves a rebuild.

For second homes, there is a specific version of this: a lockable owner closet. If you rent your place out seasonally, a well-built, properly latched closet or a partitioned section of a garage for your own gear, spare linens, tools, and the labeled leftover paint changes how the house works. It is straightforward carpentry and it pairs well with property care, since I am the one who ends up in there anyway when something needs a spare.

One honest limit worth stating: I build storage, not cabinetry. Face-frame kitchen cabinets, drawer boxes with fitted hardware, and finished furniture-grade casework are a cabinetmaker’s trade and there are people here who do it properly. What I do is solid, square, well-anchored, painted or clear-finished storage built on site to fit the space it is in.
