The plan is three houses, and two storage huts. The green represents a hedge barrier and the purple are fences for livestock. Estimated population: 20ish In-game guide: Based on Norse era longhouses, turf-houses are built with a mud brick base and a turf-roof held up by wooden support beams
I would suggest placing the buildings in such a manner that they do not block the paths towards the center of the homestead at the entrance of the wall. You would basically have to go through the building on the left to get to the other buildings if you enter from the west, or go around in a small gap to the side.
Please visualize the pathing in the layout so I can get a better grasp of it.
