<p>mathmom–I think those additions, while very expensive per square foot of new space, will add so much to your house and its functionality and resale.</p>
<p>Favorite renovation decision 17+ years ago was adding stackable washer/dryer to upstairs linen closet. Involved borrowing space from bedroom closet behind linen closet. Only trouble now is that we had the space built exactly to hold the GE stackable unit and the dryer stopped working. Didn’t seem worth even repairing dryer as it is now so old, so just went out to buy another. The dimensions changed so a new unit will not fit in the same space! Fortunately, there is another washer/dryer in the basement and some days I carry a wet load down two flights! Good exercise. Really like having two washers. I know of people who love second dishwasher, but I would have no use for that.</p>
<p>Biggest renovation regret, required by money, was not making the ground level addition a two-story addition. Bedrooms are all smallish and do not comfortably hold larger beds that teens require. Incremental cost seemed significant at the time, but then three years later, we spent the same finishing the basement. (Full bath, ejector pump, built-ins, miles of closets, etc.)</p>
<p>Can’t bear the thought of having someone in to fix/update things, but it is time.</p>
