Step-by-Step Instructions
1. Plan Your Design
-
Classic Straight Bench:
-
6 blocks (3 per side) + two 4×4 beams (seat and backrest).

8-10 blocks + multiple beams for corners.
-
2. Prep the Blocks & Wood
-
Clean cinder blocks (remove debris).
-
Sand wood beams smooth.
-
Stain or paint wood if desired (let dry completely).
3. Assemble the Base
-
Lay blocks holes facing up in two parallel rows (space them 4-5 ft apart for seat width).
-
For backrest: Stack a second layer of blocks behind the base (offset for stability).
4. Secure the Wood
-
Place beams across the blocks to form the seat and backrest.
-
For extra strength:
-
Use construction adhesive between wood and blocks.
-
OR drill concrete screws through wood into block holes.

Top with weather-resistant cushions or outdoor pillows.
-
Accessorize: String lights, potted plants, or a side table (use extra blocks!).
