Adventures in Architecture is a temporary event that is only available for a certain time in the game. During this event, you help Noah’s renovation projects.
In order to renovate the old decorations, you need Hammers. You can earn Hammers by matching special purple pieces in the levels. If you have any Hammers left when the event is over, you will receive a special reward for them.
To keep your projects in your portfolio, you need to complete them before the project time runs out. You can access all your finished projects from Noah's office across Manor Cafe.
This event unlocks at level 37.
