Not sure what modern means? Good thermal panes with argon gas, double or tripple lites, low-e coatings. Vinyl or vinyl clad wood frames Beadwalls are fun and effective. Whole house fan for when you "almost" need the air on. Hate bouncy floors, make sure they/you go conservative on those span tables. Basement "electronics lab" might be OK but have lived with a basement woodshop- never again. Groundlevel 3 bay garage with 3 bay space partitioned behind for a workshop. Woodwork, welding, drag an engine(or big heavy stationary tool) to the heated back shop thru double doors (insulated). Now we're talkin',.. woodstove to burn the scaps for heat, PV panels on all that roofspace...mmmmm. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
