Here is a single crevice house vented in the back. I used pet mesh fastened with stainless steel staples. It is covered with aluminum painted flat black. It has 3/4" spacers in back which hold it out from a wall where it is mounted and allows the bats to roost in back in very hot weather. It received regualr use from big and little brown bachelors this summer. You can see guano stains at the bottom of the landing strip.

Here is the view from the back. Spacers at the top and bottom are metal. The piece in the middle is wood. The surface has regular fiberglass mesh attached with regular staples covered with liquid nail to keep them from rusting. The access gap/vent is visible on the right side. The spacers keep the top open for maximum ventilation and another exit which the bats do use occasionally.

Here is a view from the top back side. The roof has a 45 degree angle. It looks kind of rough due to being constructed from scrap materials. But that is one of the great things about building bat houses........you can build them from many types of scrap materials that often end up in a dumpster.

Here is another similar type house with scrap shingles glued to the front. This surface warms up fast in the morning. The shingles were glued with black joe to 1/4" lauan. Spacers were needed to maintain the 3/4" crevice size. You can see the 2 sections of pvc pipe I used near the bottom. This house also has metal spacers in back and pet mesh for the baffle surface. This house received regular use from bachelors. The house on the right has a baffle surface of rough weathered plywood. It was used only a few times.

Here is another view where you can see the top where the spacers allow for ventilation and another access point for bats. I was hoping this design by providing a higher exit point would allow for a lower mounting height in situations where needed. The bats still seem to prefer exiting out of the bottom even though it is about 2' lower. The siding on my house is rough sawn white pine and hemlock and the bats seemed very comfortable roosting from it when behind these bat houses.

I really like that shingled front bat house Terry. Fantastic home on which to mount houses too! Almost every area is a mounting substrate huh? Like the options you have given for both nursery and bachelors temperature wise.

Thanks Joe, So far I have had good results from the shingle covered houses. By using scrap shingles it helps cut down on the cost. I plan on more experimentation with them.
Yes, my home does have a lot of room to mount bat houses. However after 8 years of doing this I think my bat population here has peaked due to me being too far from fresh water.
