Transforming multiple grouped SVG elements about a fixed origin

Hi. I am starting to go mad trying to resolve this, so I thought I would post a question here instead.

 

I am try to implement a rotation such that everything on the page view box (the outermost group -- depicted by the purple outline) rotates about its pre-defined origin point (shown by the cross - located at 50% 50% of view port in this case, but could be anywhere).

 

At present the resultant rotation is relative to the compound contents of the Group (i.e. all the House elements) -- spinning around itself , whereas I need it to be relative to the parent view box -- effectively spinning around a fixed point on the page.

 

So... the outer Group element ('street' in my codepen example) needs to behave like a parent-filler rather than a child-wrapper, with the origin offsets relative to the parents offset and dimensions. 

 

Note: The content items can be arbitrary i.e. multiple houses, cars etc. (set by a user), and the content may also exceed the bounds of the purple view box. None of these factors should affect the pre-defined rotation origin of the 'street'.

Ahhahhhhhhh. Excellent. That was amazingly quick & easy and testament to this Forum and the simplicity & power of GSAP.

I would also like to shout out to @SaraSoueidan. During my research I came across a set of excellent well-written articles on the subject of SVG & Transformations by Sara: https://www.sarasoueidan.com/blog/svg-transformations/

There are a lot of lurkers around here. Everyone is welcome. I think lurking for a while can be a wonderful way to learn. Congrats on stepping out of the shadows and posting your first question. Pretty soon you'll be answering other people's questions ;)

 

Happy tweening!
