We need something bigger than a shack if we are going to get any work done.

–In-game description

Small House is Core Tech which unlocks the ability for players to construct a Storm House. This research is required to research and unlock Tech Level 2.

Storm Houses are required for Tech Level 2 because they are large enough to fit a Research Bench II inside of them. They have a roof which is accessible to the player, allowing for four times the building space compared to the Small Shack.
