You have been tasked with colonising a barren planet. Arriving with limited resources you must build and reap the land to survive.
Your workers will go back to their homes to sleep and to a farm to eat when they require it.
Build a house first with a farm next to it.
Then a little ways away build a sawmill (leave enough space around it for trees) and a house near to the sawmill.
