About This Game

"We make our friends; we make our enemies; but God makes our next-door neighbour."

- G.K. Chesterton

Grandma Left Me a Building is a cozy apartment management sim where you restore the ruined building your grandma left you. Pick your tenants, manage neighbor dynamics, upgrade the building, hire staff, and handle the chaos that follows.


The walls are crumbling, the pipes are leaking, strange noises keep coming from upstairs. You're in for a long haul, fixing it all with the rent you collect. But the applicants knocking on your door are just as strange: do you go with the opera singer who bursts into an aria in the elevator, the philosopher who answers every question with "but why?", or the eight-year-old who takes apart anything within reach and puts it back together about 20% of the time?

As you welcome all these eccentric characters into your building, remember one thing: they have to get along. Wrong pairings bring chaos. The right ones bring peace. Fix up the place, hire staff, handle whatever the day brings. Grandma will be watching.
