anyone design or build any? i have an 8' opening between a house and the neighbors fence. i was thinking, a 4' wide arbor, double swing gate [(2) 2' gates]. then small fencing on either side of the arbor, with small evergreens. i'v enever built one before, but i've always been good with carpentry. was looking for some creative ideas, rather then just a box. was even thinking, make it like a "T" so potted plants can hang on either side as you walk trough. any ideas or comments? like what size wood would you use for this?
