Growing out of season in a large split greenhouse

I am currently growing a small selection of veg in a temporary greenhouse attached to the back of our bungalow and hopefully, when this poxy virus has gone and a property my wife is selling has sold, we will be getting our back garden done over and will be getting a 16' X 10' split greenhouse and having one half for cold plants and the other half for warm plants

What I hopefully plan on doing is growing veg out of season all year round so we have a continuous supply of veg.
Has anyone else tried this or are currently doing this and have got any helpful tips or advice

 

One thing springs to mind is that light can be as important as temperature and in winter the days are shorter and the sunlight less intense. It really depends on what you want to grow, leaf and root crops would probaply be fine with a bit of extra heat, but any fruiting crops and you will probably need supplementary lighting qaas well as the heat.

 

Here's a list of what I would want to be growing;
Beetroot, Beans/Peas, Broccoli, Brussels, Cabbage, Carrots, Cauliflower, Celery, Cress, Leek, Lettuce, Onion, Parsnip, Swede, Sweetcorn, Turnip & Watercress & Herbs (I know I can grow these indoors too).

 

I've hardly got any outdoor garden space as we will be having the back garden slabbed and I will be building a raised bed for my OH and that will be her little spot to plant what she wants. That's why I plan to grow what I can in the greenhouse.
