I think it goes by preference. A kitchen in the basement isn't typically the main kitchen. there is usually an additional kitchen in the basement. but if you would rather not have anyone walk through the house and you feel that it would be easier access for groceries than do whats easiest for you. this will also allow for more space on the main floor to add rooms or whatever else you want.

I would not like it! I like to have windows all around, love light and views. Basements always seem dreary to me because they are mostly underground, even with good lighting its not like having big windows on more than 1 side. But that might just be me...........

Will you have a loan for construction and for a permanent mortgag? If so, talk to them about whether or not your idea will affect the lending.

You might also want to talk to some experienced realtor to get their opinion on resale value.

Wack idea for sure. Not really good for a “forever” home at all. Forever can change in a heartbeat. You might have to sell, or you might not be able to deal with all the up and down stairs. It will never appraise for what it costs to build, and you’ll have to bring a very large sum to the table.

Are you sure your dream house involves so much walking up and down stairs? If your public living areas are going to be downstairs, how are visitors going to arrive and walk through mainly bedroom spaces to get there? Duplicate areas? As in paying for 2 100K kitchens? And 2 eating areas? And 2 living areas? At what point does this begin to make sense? At what point will you get tired of trying to pay for all of that extra HVAC and clean those duplicate spaces? Then there’s the permanent extra $$ on the mortgage for the life of the home. An extra $1200 per month to do this is a dream house? I don’t think so.

If you lived in a very old townhouse in a major city, then this would work as that's where a kitchen traditionally would go (below stairs where the servants worked). In a modern house? Just plain weird.
