Oak or Douglas fir: what is the difference?

In short: oak is heavier, harder and more durable, and the choice for large and exclusive verandas and garden buildings. Douglas fir is lighter, warmer in colour and more affordable, and a good choice for a smaller veranda. We make both to measure with mortise and tenon, half-lap and dovetail joints, in any size.

What customers choose

For large and exclusive garden buildings, pool houses and outbuildings, almost always oak. Douglas fir mainly for smaller verandas and for the modern range with a black frame.

The honest downside

Oak moves and leaches tannins, Douglas fir needs more upkeep. See treating oak and treating Douglas fir. Models by timber: oak framed veranda and Douglas fir veranda.
