    This may be covering a topic from a while back, but I couldn't find the answer I was looking for.

    I'm building an insulated internal larder in a kitchen for general food storage. At the moment I have a 100mm diam. vent entering the bottom of the larder (screened to keep out unwanted guests). The internal volume of the larder is approx. 1.8 cubic meters. My questions are: will the larder keep cool and 'aired' just with the one vent? or will in be much better to make top vent too?

    The reason for asking what may seem a 'no brainer' of a question is that the top vent (if made) is not on the same wall as the bottom vent and will involve some "imaginative" construction - although possible, I'd like to make sure that it is worth while before making it.

    Many thanks in anticipation of you comments.

    Better with a top vent too. When you say internal do you mean on an outside wall? Then uninsulate the wall and have it on the north side of the house for best results. Then insulate the larder so that it does not cool the house ( making itself warm ) totally outside would be better.

    use a metal upper vent and paint it black to get better air flow during the day. But make sure that you are not drawing in warm air.

    Yes it's on an outside wall (NW side) and it's insulated so as not to cool the house (or the house to heat the larder) - unfortunately I can't site it outside. And now I will build it with a Top vent too.

    Many thanks for all the advice - cheers!

    Always fancied a real larder. I would say you need to create the space with dense masonry...say slate/granite work top off-cuts for example (our granite work-top is always cold to the touch, even in high summer!)
    So dense masonry walls and shelves, vent bottom and top (ceiling) and an insulated door to the rest of the house. Should, in the NE or NW corner stay cool...maybe 10c...great for veg, cheese, pickles etc etc
    The peak oil forum has some further thoughts on such things...mainly from a survival point of view it has to be said.

    I want a cool larder in my planned Scandinavian wooden house. It amazes me that whilst it says on most foodstuff containers "Store in a cool dry place", yet most of us have little option but to keep it in a warm, steamy kitchen!

    I'm thinking a 'larder' is the retro 'way of the future'. I wouldn't be surprised if all new builds soon have a larder in the same way they used to have an outside toilet or a coal store. In the home of my dreams I am coming round to the fact that my the most used entrance/porch will be also be the wash room, with a larder 'uninsulated' on one side and an entrance to the 'insulated' house on the other.

    I have built in a larder in the north side of my straw bale house. It isn't vented yet, but plan to. Inside it is a very large rock with flat surface which I put my milks and cheeses on. It works very well. No fridge.

    Hi Rachel. Is your larder insulated? (to keep it cool in the summer) Is it joined to the house or a separate building? How many days at a time did your milk last for this summer? What is the floor made of? Sorry, so many questions all at once. Don't mean to bombard you.

    What do the panel think of partially/totally burying the 'larder'?

    Do I guess right, that by venting the store the draught will keep the room cooler and reduce moisture?

    What is the solution for a vented larder in an airtight house? And houldnt we have 2 larders - a cool store one on the north wall and a general store that can be "house temp" for convenience.

    It's not very insulated... only by a straw bale wall from the north, outside. The floor is insulated with both slate and limecrete on top.It is part of the house, next to the lobby and the kitchen.Milk lasted a couple of days in the summer. I do also have a hole in the ground in my lobby that I am intending to use also for cool storage. Yes, venting from outside is a good idea... just will have to keep the larder door closed...

    How about: two radiators, one in the larder and one outside above the inside one, exposed to the air and, perhaps, the cold sky, but shaded from the sun. They'd be plumbed together so when the outside one is cooler (e.g., at night) convection takes heat out. When the outside air is warmer convection stops. Would need antifreeze but no pump.

    Somewhat like the four mile island heat pipe ice box but a bit less extreme.
