Plans for Cement Block Polyurts

The cement block versions of the Polyurt are currently available only as DIY plans. These block versions are made in four sizes: 195 sq ft with 3 block long walls, 335 sq ft with 4 block long walls, 515 sq ft with 5 block long walls and 730 sq ft with 6 block long walls. The plans set is for all four sizes, all are 12 sided with the different wall lengths. The block versions are made of stanard cement block that is dry stacked(no mortar between blocks). They are then coated inside and out with a surface bond reinforced stucco material and alternate cores are filled with concrete. The roof is framed with wood and sheeted with plywood. The final roofing surface can be any standard roofing material appropriate for your area and budget.
