Seriously planning an expansion to my shop but left with a difficult
Original shop is 16' x 24' and is attached to the back of a 20' x 20'
detached carport. both are gable end roof with the shop perpendicular
to the carport. Plan is to put a 20' x20' shop expansion on the other
end of the shop matching the roof line of the carport. End up with
two 20' x 20' structures tied together by the 16' x 24' original shop,
flush on one side, 4' indention on the other.
However, when I built the original shop it was on a sloping section of
the lot and the far corner finish floor elevation is only about 3"
above grade. Shooting the grade for the expansion, I find if I flush
the floors, new and old, the slope will put the far end of the new
shop about 4" below grade.
Choices seem to be:
Do it flush and grade the property to drain properly and give me an
appropriate finish floor elevation above grade. However the down side
is that in order grade away from the shop I will have to cut down
several mature trees or seriously disturb their root systems. Trees
that will offer significant shade to the shop when finished.
Make the new section a step up of 6" and minimize any contouring of
the property, leave the trees.
Leaning toward number two, however, not sure If the step up will not
be a constant source of irritation. Anyone have a similar situation,
that is, living with a step up between shop sections?
