Gate that lasts for ages

[Luddberg]

I have taken over a property with a gate built according to Swedish Wood's building description "Gate with cross slats".

It's not particularly old but is already starting to rot away. Water has primarily penetrated all the half-lap joints, despite it seeming to be fairly well maintained regarding paint and also being in a relatively sheltered location.

We like the appearance but I have no desire to make a new gate every 10-15 years.

A couple of possible solutions:

1. I redo it with the same construction and material but do something "magical" to prevent water intrusion.
2. I redo it in Accoya, with the same construction.
3. I redo it with loose tenons instead of half-lap joints. I'm thinking double 12 or 16mm thick tenons where it is currently half-lap joints in the description.
4. Accoya and loose tenons (in Accoya).

What would you choose (or an alternative solution) and why?

Dense pine with high resin content, or oak, linseed oil/ linseed oil paint

Linseed oil paint is already in use.
Oak in those dimensions is at least as expensive as accoya, I don't even know where I would get it.
Heart pine maybe I can find...

Last year, I saw unedged oak at Bauhaus, so it should be possible to find even for those who lack their own forest and sawmill.

What is the current gate made of?

By all accounts, these are standard studs of unclear classification in the dimensions 45x95 and 45x70. Considering the result, they may not be treated. But from what I understand, the treatment doesn't go very deep, and the half-and-half cuts should've, in that case, overridden the protection, so who knows.

By all accounts, they are standard studs of unclear classification in the dimensions 45x95 and 45x70. Considering the result, they might not be impregnated. But from what I understand, the impregnation doesn't go that deep, and half-and-half cuts should have, in that case, negated that protection, so who knows.

With wall studs of spruce, I think 10 years is pretty good anyway.
