help with Greek temple definition. :-)

Hi everyone,
My name is Keren and I'm new to grasshopper.
I need to build a Greek temple, I tried a few things but I got into trouble when I got to the part of the stairs.
I can not connect them to each other and the Greek columns.
Can you help me?
It is very important that the definition is defined as a group will not change radically.
Thank you all,
Keren.
:-)
