"The only issue is that the land is completely flat and that will not allow for any exposure."

Build above ground level.

"Would it be possible to somehow add a slope in order to have some sort of exposure in the basement?"

It depends on the site.

"Are their any benefits to building on a flat lot?"

You do not have to be concerned about slope.

I can tell M. Bischak is a pro. I'll just copy from webpages, that might relate:

problem can be drainage... ??

"If you absolutely have to build a basement foundation but you are dealing with a flat lot that has poor soil for drainage purposes, then it is going to be a wise idea for you to hire a professional subcontractor that can help you with the waterproofing and drainage considerations that your home is going to need."

I know -- you can buy house, or sections of house, made well in warehouse, pre-fab, and "easily" place onto the land ?! ;)

There's an area with low, flat land not to far from here, with a string of houses that look to be built in the 60s or 70s. They're all built up on higher grade, raising the first floor finish floor level and providing for garages underneath, raised decks, etc. It doesn't seem there was enough soil in the basement excavation for all of the raised area, so soil must have been trucked in, which can get expensive.

If it doesn't have any drainage issues then you have a few ways to get windows into the basement.

1. Window wells

2. Raise the first floor higher so you can put small (non-egress) windows above grade to provide light into the basement.

3. A combo of window wells and raised so you can have larger windows.

People even build stairs down so they can put doors in to be able to get things in/out of the basement. You either use bulk head doors or regular doors and stairs leading up from a dug out area. You need to address drainage no matter what.

We currently use out basement as a Rec room. We would definitely want a finished basement.

thanks for all the responses!

Are you in an area that basements common? I am and a fair amount of homes on more slanted/hilly lots have a walkout basement. I've always loved the look and wanted one. Then one party at my SILs home cured me of that. Kitchen was up the stairs and party was down them in the back yard. I love to cook and be outside in the garden. I don't want a flight of stairs between the two.

Our lot is very very slightly sloped. We have 4 steps up to the house so the tops of the windows aren't completely below ground. Someone near us built with no steps up and his window wells in the basement are all going to need 8' ladders to get out of. Might be a slight exaggeration but they look scary deep.

What concerns do you have about the land that is located in an area where I would like to build that you do not have in your current basement? Is it that you want a walk-out basement or you do not want a flooded basement or something else?

You have not provided enough information to address whatever your concerns are. Perhaps you should talk to a local architect that can discuss your concerns while being acquainted with the geography of the area. It may save you from reading potentially irrelevant websites.

We currently use our basement for many things. Rec room, study center, art space, tv..

We would like to do that in a new house as well.

Since we spend so much time there, it would be nice to have some windows. Not necessarily a full walkout, but at least some natural light.

I do worry about the potential for flooding. although it’s not in a flood zone, I am still paranoid.

Talk to a local architect.
