At first, Invernizzi only expected the house to make a 180 degree turn, but eventually after he saw it make the 180 degree turn, he "decided to make the complete turn" of 360 degrees. The project was complete in 1935, after four years.

The Girasole has two storeys and is shaped like the letter "L". It sits on an over 44 metre circular base, with a 42 metre tall tower at the centre. This is where the house rotates from, using

. The "L" rotates "over three circular tracks where 15 trolleys can slide the 5,000 cubic metres building at a speed of 4 mm per second and it takes 9 hours and 20 minutes to rotate fully". There is a manual control panel located in the moving part of the house that is used to control its rotation. The first floor of the moving part is known as the "day zone", and includes the dining room, the music room, Mr. and Mrs. Invernizzi’s studies, with the kitchen, pantry, and toilet located right near the central tower. An assortment of bedrooms and bathrooms are found on the second floor. Villa Girasole’s
