Tell me about it nero - I have been digging all day and I now feel every one of my 50 years.
Back to work on Monday, but the count down has begun for my retirement - 4 years, 11 months and 4.5 week 
Fret not Paul, . . . at our age time flies mate.
Yes that would be great - especially when it is full of toms 
Never a truer word…
A picture would be nice—and have you remembered to put in guttering Nero?. Collect rain water into a big tub,and don`t forget to raise it/them on bricks or the tap will be too low to put a watering can under it
I’m convinced rain water is much better for the plants than tap water, ours has chlorine and flouride in it. I use it for all the houseplants and the seedlings.
Not quite finished, . . I had to pack it in, . . it was 36 degrees and I’m burned to hell, . . the place is a sun trap, . . . I’ve got 64 square foot of floor space, . . it’s cost me just under £200, . . comparing that to the cost of a ready made one of 12 X 6 X 6 which costs around £800 it’s a good saving, . . plus mine is 8 foot high.
The interior, . . those stone tubs will be good planters I think.

As you can see, the place is a sun trap.

I shall fly the Saltire from the white pole.

Why don’t you erect a lean-to hot house like mine DM, . . it doesn’t take up too much room.
Nice-but its going to get awfully hot you know?. Please find some way to put in some more ventilation. Im not being a fuss pot- just trying to give you something to think about
The vents are still to fit OG, . . one will be on each end and the door will be open on hot days. . . a vent in the roof could lead to water ingress so I’ll put them on the ends. 
LOL, Nero, me and DIY? I am a complete klutz at anything like that! Yard is 30 x 30 feet, most of it already taken up with shrubs, trees, plants and paving tiles. I’ll just enjoy yours vicariously:-D
Slightly off topic but do you have allotments in the US???
Well, I’m only familiar with what we have here in Washington; suppose it may vary from state to state. There are several here in various quadrants of the City; the one nearest me has a horrendous waiting list; last time I checked it was about 3 years! :shock:
No no, DM, . . don’t DIY, . . get someone in to do the job, . . either that or get a ready made lean-to. . . . the one I’ve just built stand on slabs, . . the floor’s easier to keep clean.
As the actress said to the Bishop, . . . . I’m really sore today, . . . . . anyways, it’s done, 
. . guess who did the christening honours, . . yeah, dirty boy Nero, . . . and the first two tennants have moved in, . . . one tom and a pepper, . . . I fitted the vent today and last night I was scratching my head as to what type of flashing I could get for the roof ends, . . then it came to me, . . a four inch plastic downpipe cut down the centre then screwed onto the sheeting’s ends.
Vented.

And the flashing.

Roll on harvest time.
salad days are on their way 
Looking good! Great job, you’re going to have fun with that. Thanks for the pics.
Those of you with big allotments and 200+ seedings coming long will probably laugh at my posting this. But it’s the beginning of my small back yard plot: two tomatoes, three chilis and two basils, all happy on the windowsill in their pots. The onions and potatoes will go in later. There is one more tomato that hasn’t germinated yet.

I`m not laughing DM-more applauding because the smallest back yard can be a garden.
Nero-it looks good-you will not regret that ventilation
Another busy day doing finishing touches and tying up loose ends, . . serviced the wife’s car today too, . . must get some of those seedlings potted up tomorrow, . . . the temp in the hothouse will have to be watched closely though, . . the sun was really hot today so I put up some blinds and the temp came down slowly to a reasonable level.
How close do you plant the toms, is it 15 or 20 inches ? . . . can I plant peppers in between them ? . . . . anyone tried growing melons ?
