Basement master suite: advice? regrets? inspiration?
Has anybody created a basement master suite as part of a remodel? I'd be curious about your experience with choice of flooring, hvac choices, window styles, layout in relation to the outside, etc. -- anything you love about your new space or don't like and would do differently if you had it to do over.
Here are the basics of my situation: I have a 90-year-old, 1100-sf, one-storey bungalow with two bedrooms on the main (only) floor. My planned addition is ~325 sf to contain a new dining/sitting area overlooking the back yard and back entrance with mudroom, with the current back bedroom in the original house becoming a new kitchen adjoining the addition.
Since I'm losing a bedroom to the kitchen reconfiguration, I'd like to create a second bedroom. The choices are to go up or go down. Since there will be a basement under the addition anyway, the obvious thing would be to finish that space. My lot slopes to the rear, so the basement under the addition will be about 5' above ground on the south and east walls, with room for windows along the entire east wall and about a 13' run of the south wall. (The attached picture shows the existing addition, which will be demolished, but you can see in the pic how much frontage is exposed above the ground and below the level of the addition's floor. That would almost all be available for bringing light into the new basement space.) The new back entrance would be a half flight up from the basement level and a half flight down from the main floor, so we can plan appropriate egress from the basement.
(I know a lot of people don't like basement bedrooms, but for my money, I *really* appreciate how much cooler a basement room is in our super-hot summers. This is my forever home, so the room would be for me and resale is not my top concern.)
Any thoughts, experiences, pros, cons, or cautions?
