The current map is very barren and the distance between point of interests (ie, festival site, player house or even towns) are way to far apart. adding more player houses would be an easy way of padding up empty spaces.
Agreed, I’d like to have house especially on the top of the volcano, so that I can spawn there every time I launch the game (and begin playing with glorious downhill!) 
Id like to see this. H4 has twice the amount of houes compared to 5.
I would be happier to see this in horizon 6. Horizon 5s ship is sailed long ago to expect anything good coming
