The ideal would be a home in the air - zombies can't fly!
However, hot air balloons and zeppelins are hard to come by.

Zombies do have a reaction to UV (sunlight), so if you had a reliable source of power you could "barricade" your house with UV floodlights.

Zombies probably need air to live, so if you had access to a submarine somehow, that would be good too.

None of which plans would work for me.
