In my opinion no. The reason being - It measures 4ft externally, not internally, the ground floor is too exposed so I wouldnt count it as part of a hutch and take away the size from the hole and ramp and 3 piggies dont have much lap/popcorning space
I've noticed a few threads you have stated wanting advice on hutches.
Where abouts are you and how much do you have to spend?
I'm sure we can come up with a great hutch if you tell us what you want, someone on here might even have one for sale near you
