Tiny Eden Rooms, Expansion & the Rooftop

How far the apartment goes

You start with a few pots and whatever space you can find. From there you unlock new rooms, use the balconies, and eventually reach the rooftop greenhouse. The ceiling, per the developer FAQ, is several hundred plants indoors and on the rooftop combined.

The achievement Latifundist — unlock all rooms in the apartment — marks the end of that progression. At 0.1% global unlock the day after launch, nobody had finished it yet.

Each space is a different climate

This is the part that changes how you plan. The FAQ confirms every room and balcony has unique environmental conditions and that layout affects growing efficiency directly. The temperature ordering is worth committing to memory:

Balconies are warmer than the rooftop, but colder than indoor rooms.

So expansion is not simply more pots. Unlocking a cooler space opens crops the warm rooms could not hold, and vice versa. The light and temperature guide covers the tools for correcting each.

The rooftop is not just the last room

The FAQ calls the rooftop a key part of the game and says plainly that some plants can only be grown there. It is also where the database quest hand-off happens, between 21:00 and 23:00 — see the drones page.

Paying for the next room

This is where new players get stuck, and it is a common enough confusion that a streamer with a 54-minute demo playthrough ended the video still asking how to pay for the second room. The blocker is almost always liquidity rather than a missing mechanic: money comes only from cooked dishes sold, so if the kitchen loop is not running yet, nothing accumulates. The money guide covers the earning chain, including the launch-week bug that stops the retail unit selling entirely.

Decorating and what you cannot change

You can change walls and floors, expand the apartment and unlock the rooftop. You can customise materials — but not the layout geometry. And two elements are fixed: the kitchen and the lab stay where they are, no matter how completely you convert the rest of the flat into growing space.

The achievement Personal Touch, for customising a planter, was the second most-unlocked achievement in the game a day after launch at 2.9%, which suggests most players start decorating almost immediately.

Hothouse

One of the five hidden achievements is called Hothouse. Steam publishes no description for it and Bajka Games has not explained the trigger, so this page notes the name and leaves it there — but given the rooftop greenhouse and the temperature system, it is the achievement most likely to be tied to this progression.
