I want the clickable area to be on the building itself and not on empty areas of the picture.

You want this property on the images input handler:
http://phaser.io/docs/2.6.2/Phaser.InputHandler.html#pixelPerfectClick

Setting that to true will only register clicks that are over areas of the image that have an alpha value on and above the pixelPerfectAlpha threshold.
