My OH is quite good at offering to build me things (when time allows).
He asks me what I want, I make it clear. then he builds something HE thinks would be better.
Unfortunatly he doesn't have much to do with the animals, so usually what he builds never gets used.
Like the goose shelter in the bottom field. 3' high, door facing south in the long side I asked for, got a door in the end so the geese never went into the long 'tunnel'. however the hens decided to lay in there and I have to scramble right to the end to get the eggs
