Over Possessive Father With Seperation Issues

My next big project was going to be a network of step down porches outback with the one closest to the house being inclosed for the wife's plants and coffee room.  I also need the cooking and entertaining areas to be a little more functional than they currently are.
The designs have been drawn out, material lists have been made and the start date was not too far off on the first phase, but....

I get a call from the oldest daughter last week and she said she is changing her major and after getting her degree at A&M she is moving back home to get her Doctorate at the local college. Of course I am all for it and before she was finished talking the little wooden wheels in my head had already started spinning.

I asked her if she was wanting to live in the house or what was she planning.

"Dad, I will be 23 years old and I really don't want to live in the house unless I have to". Is what she said.

I fully understand that and support her decision on it, but it would be a waste of money for her to rent a place in town when she is within driving distance to the college. So, the next best thing is to build her an apartment out back.

Now, by that time the middle daughter will be 21 and attending the local college as well. I do not see any reason she needs to waste money on rent or housing either. So the plans include a small condo type of building. Yesterday while at work I quickly drew up a little floor plan on two 12X12 rooms with a build in desk.   



 I know this picture is hard to see, but if you turn it sideways you get the idea. The condo will not have a bathroom in it because the bathhouse is only thirty feet from it. Plus the main house will be there for them when they need it. Momma will still do the cooking, but they will have their own refrigerator and microwave in there for quick meals.
I was thinking on putting on a small community washroom in the back they could walk into so they will have a quick place to do there makeup and brush their teeth, but I am still undecided on that one.

Here is the problem with the design. By the time all this takes effect, the youngest will be nineteen and will be graduated high school and going into her first year in college. Now I don't know if I should go a head and build three in a row or just the two and tell the youngest to stay in the house.
Ultimately it is their choice to stay or go, live there or live elsewhere, but if I was to give them a free spot to live they can call their own and could save money until they started their careers, then they might stay around for a little while and still have the freedom of living on their own, kinda.

I know this is a big build and one that is kinda possessive. No, I never want my girls to leave, but I do know eventually they are going to. I am just thinking while they are in college this would be a great way we all stay together and they save money.

What's your thoughts on this? Is this over the top and I have possessive and separation issues, or is this something that a good dad would do to help his kids out?  Would you have lived in something like this while going to college if it were an option?
I am in the middle on this one.
Thanks for your feedback.        

Another Chili Post, Plus Some Other Stuff

For some reason this weekend took more out of me than was expected.

 The Whitewright Fireman's Chili Cook Off was a success. Our team had a blast and made a great haul with over $1600.00 in different prizes. As far as the chili goes, one team mate got third, the wife got tenth and apparently me and the other team mate didn't even show up.
Our booth got 2nd in show, but I expected that being we were in the lion's den so to speak. At a Fireman's Fest, with Firemen judging the booths. Go figure, First place went to a Fireman, but that's cool I guess. It's kinda like homecoming, no matter how good the underclassmen build their floats, the senior float always get first place. 
I want to say thanks to all those who came out to show their support for our team. It was good to see everyone. 

I was also able to get the trophies finished for the November 18th Chili Cook Off in Denton. This was a team effort with one half doing the staining and painting and me and the wife doing the cutting and assembling. I think they turned out amazing.
Just for the fun of it I made two more trophies not pictured here. Honorable Mention and Sexiest Cook. Those are not really ever done so I thought why not.

I never meant for this to turn into a Chili Cooking Blog, but it kinda has because that is what I'm into at the moment. So if this does not interest you in the least bit, sorry.

I was able to get some other stuff accomplished this weekend though. I had all my girls with me and you see, they have this dog. It's a dog I do not want, but they have banded together to form their own democracy to fight me on keeping this dog. This dog has tore up and broke many things outside and that is one of the reasons I don't want him. Some others are the fact he in almost a hundred pounds, still a puppy, barks all the time and the list goes on and on. So anyway, being I had them all there I had them fix some of the things their dog has tore up. One being the water line their dog ripped up and broke going to the gardens.
It was painful to watch but after a while with my instructions the lines was fixed. I had the girls also clean where the dog took my outdoor cushions and decided to tear them into little pieces along with two extension cords and water hoses. Yep, he needs to go. 

Other than that, thanks to a buddy of mine who is a professional beer drinker I have now collected more than enough cans to get the Solar Heater built.
This week I will be working on that along with fixing my weed eater, mowing and repairing more stuff the dog has destroyed.   
    
Y'all have a great week.
