The Universal—Accessible Garden’s
20 Degree Raised Bed: 6’ wide x 5’deep
Materials:
Composite boards: 12’ boards - 11
(A) 4” x 6” x 8’ lumber – 1
(B) 2” x 6” x 8’ lumber – 4
(C) 2” x 4” x 8’ lumber – 3
(D) 1” x 6” x 8’ lumber – 1
Screws - 3”, 1”
Flat brackets
90 degree angle brackets
Making the base:
Cut the single (A) into 18” pieces. Cut the top of each 5 ½” long by 1 ½” deep creating a wedge that is a 2” square, 5
½” long.
Cut two of the (B) to 6’ lengths. Cut the other two (2) 56” long. Set these onto the 18” (1) and screw into place
forming the base.
Cut the (C) into 3’ lengths. Cut one end of each of the six pieces at an angle so the boards sit at a 20 degree angle.
Cut the (D) to 6’. Place this board at the peak of the 3’ pieces and screw into place.
Making the bed:
Cut 8 of the composite boards to 6’ lengths. Screw lengthwise onto (C). Screw 2 composite 6’ boards together to
form a 10 ½” height, using flat brackets. Attach to peak.
Screw 3 angle brackets to base of composite at the three (C). Attach two composite boards to form a 10 ½” height.
Do same on opposite side.
Cut 4 composite boards to 36” length and 4 to 33.5” length. Attach 2 angle brackets to each sloped side at edge.
Attach two composite boards to each side to form a 10 ½” height on each side.
Fill with soil. Place dividers where needed and attach with angle brackets to avoid having them slide downward and
to prevent soil movement downward and to segment growing areas.
