Wooden Pergolas: Timber That Lasts Outdoors
A wooden pergola kit in Ireland costs €428 to €733 for a 2.4 m square up to a 3.4 m corner pergola in pressure-treated softwood. Larger timber pergolas are built to measure by a carpenter and priced on the job. How long one lasts comes down to one detail: the posts must sit on metal shoes above the ground, never in soil or concrete.
The timbers, the sizes, and the detail at the foot of the post.

Which timber
| Timber | Where you'll see it | Looking after it |
|---|---|---|
| Pressure-treated softwood | What most kits are | Re-treat cut ends. Stain or oil every two to three years |
| Larch or Douglas fir | Heavier sections, built by a carpenter | Weathers to silver if left. Lasts longer than softwood |
| Oak | Green oak frames, pegged joints | Moves and cracks as it dries. That's normal |
| Glulam | Long spans without a middle post | Factory made. Needs a finish kept up |
The foot of the post

Timber rots where it stays wet, and that is at the ground. A post set in concrete holds water around its base and fails there first. A post bolted into a galvanised shoe, with a gap under it, dries out after every shower. Ask how the posts will be fixed before you ask anything else.
Sizes that work
- 2.4 m square: a bench and a small table. The smallest stock kit.
- 3 × 3 m: four chairs, or a corner sofa.
- 3 × 4 m: a table for six. Usually built to measure in timber.
- Over 4 m: needs a deeper beam or a middle post.
What timber costs
| Job | Typical cost | What moves the price |
|---|---|---|
| Timber pergola kit, 2.4 m square to a 3.4 m corner | €428 to €733 | Size and timber. Fitting and a base are extra |
| Side screens and blinds, a side | €265 to €489 | Width, fabric or slats, fixed or sliding |
A timber kit is delivered, not built. A carpenter's day, post shoes and a base are extra.
Wood or aluminium?
Timber is cheaper, warmer to look at and easy to alter. It needs a coat of something every few years. Aluminium costs more, needs nothing but a wash, and is the one that takes a louvred roof: see aluminium pergolas. For building detail, see pergolabuilders.ie.

Questions people ask
How long does a wooden pergola last?
A treated softwood pergola with its posts off the ground and a finish kept up lasts many years. Posts set in soil are what fail early.
Can a wooden pergola have a roof?
Yes: polycarbonate sheets on the rafters with a slight fall.
Will it hold a swing seat or a hammock?
Only if it was built for it. A kit pergola is sized for its own weight and climbers.
