Why We Build With Birch Plywood (And Why We Love It)

We build with birch plywood because it is strong, honest, and beautiful exactly as it is. Birch plywood is an engineered wood made from thin layers of birch veneer glued together with their grain crossing at right angles, which makes it far stronger and more stable than solid wood of the same thickness. We love it because that strength lets us build light, slim, lasting furniture, because the layered edge is a detail worth showing rather than hiding, and because it is an abundant, fast-renewing wood, a pioneer tree that grows in huge numbers where we live, rather than a scarce or threatened one. Here is what birch plywood is, why we use it, and how it lasts.

What is birch plywood?

Birch plywood is an engineered wood panel made by stacking thin layers of birch veneer, called plies, and bonding them under heat and pressure with the grain of each layer turned 90 degrees to the one beneath it. That cross-grain construction is the whole trick: wood is strong along the grain and weak across it, so alternating the direction layer by layer gives a board that is strong and stable in every direction, far less prone to warping, splitting, or shrinking than a solid plank.

The premium version designers reach for is often called Baltic birch, made in Northern Europe from many thin, even plies with very few internal gaps. Because the layers are visible at any cut edge, birch plywood has a distinctive striped edge, a fine line of pale laminations that we treat as a feature rather than something to cover with banding.

Why we build with birch plywood

We design furniture for small homes, which means our pieces have to be slim, light, and strong all at once. Birch plywood lets us do that. Its strength-to-weight ratio means a thin panel can carry real load, so a shelf stays flat, a stool takes an adult's weight, and a wall cabinet holds your things without needing to be bulky. A solid-wood version of the same piece would be heavier, more expensive, and more likely to move with the seasons.

We also simply like how it looks. The pale, fine grain has the calm, warm character that suits a Scandinavian interior, and the layered edge gives a clean, honest line that shows exactly how the piece is made. That is why, on a piece like Levitate, we leave the birch plywood mechanism on show instead of hiding it behind plastic. Good materials, well made, do not need covering up. It also pairs beautifully with colour, which is why we so often combine birch plywood with through-coloured Valchromat.

Is birch plywood strong and durable?

Yes. Birch plywood is one of the strongest and stiffest common plywoods, thanks to its many thin plies and dense birch fibre. The cross-laminated layers resist bending and twisting, and they hold screws and fixings well, because there is solid, even material right through the board rather than a soft core. For furniture, that means thinner panels can carry more weight and joints stay tight over years of use.

It is also dimensionally stable. Where a solid timber board expands, contracts, and can cup as humidity changes, the opposing grain directions in plywood hold each other in check, so panels stay flat and true. Treated and used indoors, a well-made birch plywood piece will easily last for decades.

Property	Birch plywood	Solid pine / softwood board
Strength for its weight	High, strong in every direction	Lower, strong only along the grain
Stability with humidity	Very stable, stays flat	Moves, can cup or split
Screw and joint holding	Excellent, solid through the board	Good, but can split near edges
Edge	Clean striped laminations, a feature	Plain end grain
Best for slim, light design	Ideal	Needs more bulk for strength

Is birch plywood sustainable?

It can be a genuinely responsible choice, and it is one of the main reasons we love working with birch. Birch is a pioneer species: one of the first trees to take hold on bare, open ground, quick to colonise a cleared field or a forest edge, and quick to regenerate. In our part of the world, across Scandinavia and the Baltic region, it grows in enormous abundance, so building with it does not draw on a scarce or threatened resource. It is fast-growing too, regrowing far quicker than slow-maturing timbers, and plywood uses the tree efficiently by peeling it into thin veneers rather than cutting thick boards with offcuts lost along the way.

The thing that still matters most is where it comes from, which is why we use FSC-certified birch plywood, so the wood is traced to responsibly managed forests. Building to last is part of this too: a slim, strong piece that survives decades of use, and that can be re-oiled rather than thrown away when it looks tired, is far kinder than furniture you replace every few years.

How we finish and care for it

We finish our birch plywood by hand in our Copenhagen micro-factory, usually with a hard wax oil that soaks into the wood rather than sitting on top as a film. The oil brings out the grain, adds a soft natural sheen, and gives a surface that resists everyday moisture and marks while staying repairable.

Care is simple. Wipe with a soft, slightly damp cloth, avoid soaking it or leaving standing water, and skip harsh or abrasive cleaners. If a surface ever looks dry or worn after years of life, a light re-oiling brings it back rather than calling for a full refinish. Used indoors and looked after, birch plywood ages gracefully.

The pieces we build in birch plywood

Birch plywood is the backbone of several of our designs. Levitate uses FSC-certified birch plywood for its visible pull-down mechanism, paired with Valchromat and solid oak. Our Bjørk stool stands on warm birch plywood legs under a through-coloured Valchromat seat, and the matching Bjørk dining table carries the same honest combination of pale plywood and colour into the heart of the room.

Frequently asked questions

What is birch plywood made of?

Birch plywood is made of thin layers of birch veneer, called plies, bonded together with adhesive under heat and pressure. Each layer is laid with its grain crossing the one below at 90 degrees, which is what gives the board its strength and stability in every direction.

Is birch plywood good for furniture?

Yes. Birch plywood is strong, stiff, and dimensionally stable, holds screws and joints well, and has an attractive layered edge, which makes it an excellent furniture material, especially for slim, light, lasting pieces. It is widely used in Scandinavian and design furniture for exactly these reasons.

Is birch plywood stronger than solid wood?

For its weight and thickness, birch plywood is generally stronger and far more stable than a solid board of softwood, because its cross-laminated layers resist movement and carry load in every direction. Solid hardwood can be very strong too, but it moves more with humidity and is heavier and usually more expensive for the same panel.

Is birch plywood eco-friendly?

Yes, when it is responsibly sourced. Birch is a pioneer species that grows quickly and in great abundance across Northern Europe, so it is not a scarce or threatened wood, and plywood uses the tree efficiently. The key is certification: we use FSC-certified birch plywood, which traces the wood back to responsibly managed forests.

How do you care for birch plywood furniture?

Wipe it with a soft, slightly damp cloth, avoid standing water and harsh cleaners, and keep it indoors. Most quality pieces are oil-finished, so if the surface ever looks dry or worn, a light re-oiling restores it rather than needing a full refinish.
