Hello.

The building complex, including its canteen and playground, is still under constraction.
A canteen and a playground belong to this building complex. It's a single unit.

Will is be right here, as I refer both canteen and playground to the building complex?

Are you sure you meant "contraction"? I think you might mean "construction".

Yes, you are right. I edited my original post.

Use is because you're talking about the building complex. The other features are all part of the complex.
