Vernon asked me to build one with the reduced height porch of the "Steve", but with inside dimensions of the "Miriam". He wants to use it as a recreational space, as well as gardening and art activities, so the roof is double glazed for greater comfort and warmth. The double glazing should also reduce the extremes in temperature - less chance of frost in winter, or scorching the plants in summer. Most most heat loss and sun will come through the roof so we left all the vertical elevations in single toughened glass.
I pre-joint all the timber sections in the workshop before painting it in my new painting shed at home. Your greenhouses is just a pile of wood when I arrive but within an hour the structure is jointed together and I start the job of filling in all the glass, glazing bars and supports.
