Barricade your cottage by destroying wooden props such as chairs, crates, tables etc to get wood. Then use this wood to repair or board up windows to hold off attacks. Once you are ready, activate the radio to signal the invasion. Hammers located at the doors repair doors. Hammers at the windows build a barricade. Weapons are located in the bedroom, in the outside loo, and other places around the house. You will need to look around the inside of the house for the radio.
