The next morning, Rebecca walked over to a lean-to to check for their hikers' logbook.
The internal arrangement of a lean-to mushroom house is shown in fig.
A lean-to against the north side of the garden wall will be found suitable for the purpose, though a span-roofed form may also be adopted, especially if the building stands apart.
The lean-to is the least desirable form, since it scarcely admits of elegance of design, but it is necessarily adopted in many cases.
Except where space does not permit a span-roofed building to be introduced, a lean-to is not to be recommended; but a house of this class may often be greatly improved by adopting a half-span or hipped roof - that is, one with a short slope behind and a longer in front.
The heating and ventilating arrangements are much the same as in the lean-to, only the top sashes which open are on the back slope, and therefore do not interfere so much with the vines on the front slope.
The lean-to house is in most respects inferior to the span-roofed; one of the latter could be converted into two of the former of opposite aspects by a divisional wall along the centre.
6) is a combination of the lean-to s and the span-roofed, uniting to a great degree the ad vantages of both, being warmer than the span and lighter than the lean-to.
Orchard Houses are span-roofed or lean-to structures, in which various fruits are cultivated without the aid of artificial heat.
A span-roofed house, being lighter than a lean-to, would be so much the better for peach culture, especially for the crop grown just _.
