I've a 4ft by 4ft windo that I am planning to use to make a cold frame. I
intend to concrete the floor then on this lay bricks to a height of 15cm
at
the front and 55cm at the back giving a slope on the window (roof).

Does this sound adequate for height, we are new gardners and builders and
see it being used for seedlings to go on into the veg plot. Would a deeper
cold frame be an advantage for other plants?

How tall are your plants going to grow before it gets warm enough to put
outside? If crowded they may change their growth pattern.

On the building side would I need to add plastiser to the mortar and use a
DPC?

I just used a putty gun and filled in the openings against the house. I
also bought some thin stryofoam insulation and lined the inside of the box.
Then I got some plastic jugs, filled them with water and lined them around
the walls to help with the heating during the night time.

Good luck. Dwayne

thanks for any tips,

Dave
