Hello there and welcome to the forums

Go to the avenue, and then click the chair icon at the bottom of the game screen to go into Room Edit Mode. Once there, click on the '+', and a box would appear with choices of which houses/avenues you would like to attach

Click on your preference.
As to have them remain attached, decorate
both rooms with at least one item of furniture each. Otherwise, a glitch would occur which, when you refresh, the avenue/house will not be attached.
