Anyway, as per my "offer to help" on the last meeting re tiles I have done a quick calculation on "just flooring" tiles for those listed on the shared plans on our link  (btw , thanks Sander and others for the beautifully crafted place / info & spreadsheets to share to all) .

So, within "Custom Choices" I have created a new spreadsheet for "tiles / flooring" . - and note, I just done flooring, because I noticed for example Gay in M3 has walls as well , but I am leaving walls for later in case more on this is needed. 

As it was nicely said by Rainer , it is mainly D Units + M3 that requires tiles in a few wet areas. 

I will list the calculations I have done below -but remember  these are in the spreadsheet mentioned above : 

UNITS D1-D6 : 

Toilet @ entry level  = approx. 1.2m2 ( if you are using 250mmx250mm tiles = 24 tiles) 

 - D1 is a little bit bigger but doesn't make much difference 

Now; to note, I haven't read the minutes yet and my assumptions may be incorrect.

Happy to answer any questions so please fire up or get me at the meeting .

Also , we got together with Jan Burch to start giving some shape to the "JOB SHARING pre- Moving to Cohousing" and we started a spreadsheet , we can talk about this later on and on the next meeting. 

Have a great rest of the week, and the weekend. 

Regards,
