Teak, Guanacaste, or Cedar: Choosing by the Wood

A wood is a set of decisions the tree made before you ever met it. How fast it grew, how much oil it laid down, how it moved through wet and dry seasons. By the time it reaches a workshop in Jepara or a mill outside Liberia, those decisions are fixed. Your job is only to read them. Teak, guanacaste, and cedar are the three woods people ask us about most, and they are not interchangeable. They ask different things of a room, and they give different things back.

What the oil tells you

Teak earns its reputation in the first fact you learn about it: the oil. Old-growth Javanese teak carries a natural silica and resin content that repels water and insects without any help from a finish. This is why the Dutch built ship decks and colonial verandas from it in the 1800s, and why a teak table left on a Bali terrace for a decade greys but does not rot. The teak we spent years sourcing across Java and Surabaya was mostly reclaimed — pulled from Dutch colonial houses, warehouses, and joglos built in the 1920s and 1930s, when the trees were felled slow and old. That age matters. Plantation teak grown for speed has wider rings, less oil, and a paler, blonder look. Reclaimed teak reads darker, tighter, and denser. You can feel the difference before you can name it.

Guanacaste is a different animal entirely, and Costa Rica's own. What the trade calls suar in Indonesia is the same genus you see shading a pasture in the province it is named for — the great spreading rain tree, cross-cut into a single wide slab. Its character is the grain: dramatic bands of pale sapwood and deep chocolate heartwood, often with a live edge that follows the trunk. Guanacaste grows fast and wide, which is exactly why it yields tables you cannot cut from teak — a dining top from one board, two meters and more, with no join down the middle. It is softer than teak and less oily, so it wants a finish and it wants to live indoors or well under cover. What you buy with guanacaste is scale and movement. No two slabs repeat.

Cedar — and here we mean the tropical Spanish cedar, cedro, not the aromatic North American kind — is the quiet one. Light, stable, and fragrant, it was the wood of choice for cabinetry, doors, and cigar boxes precisely because it stays put. It does not swell and shrink the way denser woods do, so it holds a drawer true and a door square through a Central Valley rainy season. It carves cleanly, which is why you find it in the fretwork and louvered shutters of old houses. It lacks teak's armor against weather, so it belongs inside. But for a piece that must open and close and fit for fifty years, stability is the whole point.

Where the joinery lives

Wood is only half the story; the other half is how it was put together. The Javanese workshops in and around Jepara, the carving town on the north coast, still build the way they did generations ago — mortise and tenon, pegged, glued sparingly if at all. A joglo frame was raised without a single screw, its great columns and beams locked by geometry so the structure could be taken down and moved. That tradition is why a reclaimed teak cabinet from that lineage feels solid in a way a stapled carcass never will. When you press on it, nothing gives.

This is where the three woods diverge again in practice. Teak's density and oil make it unforgiving to work and slow to glue, so good teak joinery is almost always mechanical — pegged, tenoned, earned. Guanacaste, being a wide slab, is less about joinery than about the base that carries it and how the maker has stabilized the board against splitting as it dries. Cedar, soft and cooperative, takes fine joinery and carving with ease, which is its whole argument. Learn to look at the joint, not just the surface. The finish flatters; the joint does not lie.

Choose teak if the piece will meet weather, water, or a lifetime of use and you want it to outlast you. Choose guanacaste if you want one honest slab, generous and unrepeatable, at the center of a room. Choose cedar if you want lightness, fragrance, and the kind of stability that keeps a door true. None of these is the best wood. There is only the right one for what you are asking it to do.

Most of this is easier to understand with your hand on the grain than on a screen. The collection is kept at our showroom-home in Escazú, and we open it by appointment for those who want to see how these woods behave in person.
