Hello House,

I have a small building project consisting of 10 rooms in a straight line intended for student accommodation. Each room is 10 x 12 feet size with ensuit bathroom and small kitchen area. Attached is a picture of the site.
The construction is almost at lintel level and reading through nairaland has helped shaped my understanding a lot especially with pricing, and structural guide posts that should/ should have been done. Now:
1. On the importance of german floor. Can flooring before roofing help the structure of the house because i did not do german floor before block setting. The house is on a good soil structure
2. what is the likely cost of roofing. Wood and iron sheet.I intend using reasonable cheap but good quality aluminium roofing sheet.
Thank you
