Workshop to rent 1500+sqft london arear

I need to find a bigger unit for my business so if anyone knows of any 1500sq ft with a small yard would be perfect for me.

Looking for around 1500+sqft but ideally want a yard for 6-7 cars, I am in NW london at the moment but would'nt mind moving a little further out if the unit is right, and doesn't have to be immediatley either.

Thanks
