4. Ocean Floor Cottage

An ocean floor cottage brings countryside charm underwater. Built low and wide, this house uses stone bricks, spruce wood, and moss blocks to create a cozy, grounded structure. The roof is slightly slanted and decorated with kelp, coral fans, and sea grass to make it look naturally overgrown.

Windows are smaller and framed with dark wood, giving the house a warm, cottage-like feeling even beneath the sea. Inside, the design is simple and homey—fireplace designs using magma blocks, soft carpeted floors, and compact rooms that feel safe and comforting.

This idea is perfect for players who prefer cozy aesthetics over grand designs. It also works well in survival mode since it doesn’t rely heavily on rare blocks.
