I’m creating an enclosed outdoor area for my cat and would like to make some cost-effective wall furniture (shelves, resting spots, climbing posts etc) similar to the inspo picture.
The wall area is somewhat sheltered under the eaves but may be exposed to rain with wild weather and direct sun in summer. Would a pine panel cut to size and treated with outdoor decking stain (or similar) be ok in this area, or am I going to need to use treated pine or marine ply? I’m looking for the best value option for making a series of shelves of various sizes. Would prefer a timber look for aesthetics. Any advice welcomed!
