A 1,000 sq ft basement fits anything from one open family room to a family room with two bedrooms and two bathrooms. In BuildFlow's pricing the open family room is $53,000–$62,000, a family room with a bedroom and bath $66,000–$76,000, and two bedrooms with two baths $78,000–$90,000.
The layout is mostly decided by three fixed points: bedrooms go on an outside wall for the egress window, wet rooms go near the existing drain, and the mechanical room keeps clear access.
Start with the fixed points
Every layout below is drawn on the same reference basement: about 1,000 square feet in a 1985 to 2015 Twin Cities house, with a steel beam on posts down the middle, a duct trunk beside it, the furnace, water heater and panel in one corner, a sump in another, the stairs landing near the middle of one long wall, and a bathroom rough-in near the main stack. These fixed points decide most of a layout before any choice is made; what you're working with describes each one.
Three rules shape every plan: wet rooms (bath, bar, laundry) go near the existing drain; bedrooms go on an outside wall where an egress window can be cut; and the mechanical room keeps clear, direct access for service. Each price is BuildFlow's pricing engine for that layout at about 1,000 sq ft, standard finish, run October 10, 2026.
Ten layouts, priced
1. The open family room: $53,000–$62,000
Who it's for: Families who want one big flexible room for TV, play and guests.
The whole finished area is one room, with the TV wall on the long interior wall facing away from the window wells and the stairs landing at the side of the seating, not behind it. The mechanical corner stays unfinished behind a wall with a door. This is the least expensive way to finish the space, and the easiest to change later.
Watch for: The beam and posts. Plan the furniture so the posts fall at the edge of zones, not in the middle of the seating, and wrap them so they look intentional.
2. The media room with a built-in wall: $63,500–$73,500
Who it's for: Movie and game families.
The open plan from layout 1, with a full-height built-in wall around the TV that also absorbs the duct soffit where it crosses. Seating sits at a distance of roughly 1.36 to 1.86 times the screen width, the range that gives a cinema-like to everyday viewing angle.
Watch for: Light from window wells across from the screen; plan blackout shades or put the screen on a wall without windows. See media rooms.
3. The entertainer: bar, built-ins and a half bath: $77,000–$87,000
Who it's for: Hosts who'll have people over more than they'll have overnight guests.
A wet bar with a stone counter sits on the wall nearest the plumbing stack, the half bath right beside it to share drain lines, and the built-in TV wall on the opposite end. The stair landing opens to the bar, so guests arrive at the drinks.
Watch for: The half bath costs nearly as much as a full bath; if guests may ever stay over, consider layout 6.
4. Family room plus a bedroom: $58,000–$68,000
Who it's for: A family that needs a guest or teen room but not a bathroom yet.
The bedroom takes a corner on an outside wall for its egress window, away from the mechanical room's noise. The family room keeps the center and the TV wall. Have the plumber stub the bathroom drain and vent where a future bath will go while the walls are open.
Watch for: Bedroom size and ceiling height: a bedroom needs at least 70 sq ft and the code's minimum headroom, which beams and ducts can eat into.
5. Family room, bedroom and bath: $66,000–$76,000
Who it's for: The most common basement I design: a true guest floor.
Bedroom on an outside wall, bathroom between the bedroom and the family room so guests have a short private walk, both near the rough-in. The family room keeps the open center. A small closet under the stairs or beside the mechanical room adds storage.
Watch for: Where the bathroom drain is. If there's no rough-in or it's below the sewer line, see ejector pumps.
6. Guest suite with a wet bar: $74,500–$84,500
Who it's for: Families with frequent overnight guests, or a parent who visits for weeks.
Layout 5 with a wet bar between the bathroom and family room, on the same wet wall. The bar becomes a coffee station in the morning. A small fridge here keeps guests out of the upstairs kitchen. See kitchenettes and guest suites.
Watch for: Whether your city treats a full kitchen downstairs as a second unit; a wet bar usually doesn't raise the question.
7. The winter family room with a fireplace: $71,500–$81,500
Who it's for: Minnesota families who'll spend winter evenings downstairs.
Layout 5 with a linear gas fireplace on an outside wall, under or beside the TV, with seating facing both. A direct-vent fireplace needs an outside wall and a legal place for the vent outside.
Watch for: Clearances between the fireplace and the TV set by both manufacturers. See fireplaces.
8. Bedroom, bath and a home office: $69,000–$80,000
Who it's for: Anyone working from home who needs a door that closes.
The office takes the quietest interior room, away from the mechanical room and the bathroom's drain stack, with good lighting on dimmers. It can share an outside wall with the bedroom if it may become a second bedroom later, in which case it needs its own egress window.
Watch for: Noise from the furnace and laundry. See gyms and offices and soundproofing.
9. Two bedrooms and a bath: $71,000–$82,000
Who it's for: Teens, or two kids who'd each like their own room.
Both bedrooms on outside walls, each with its own egress window, with the bathroom between them and the family room at the stairs. Hallways stay at least 3 feet wide. The family room gets smaller, so a floating console TV wall keeps it open.
Watch for: Two egress windows means two window wells; check yard setbacks with your city.
10. Two bedrooms and two baths: $78,000–$90,000
Who it's for: A teen suite plus a guest suite, or a long-term live-in family member.
Each bedroom gets its own bathroom, placed back to back on one wet wall to share drain runs. The family room keeps the stairs and the TV wall.
Watch for: This is the most expensive layout here because of the second bathroom. See what each upgrade adds.

Design my basement with EmmaQuestions people ask
How many bedrooms can you fit in a 1,000 sq ft basement?
Usually two, each on an outside wall with its own egress window and at least 70 sq ft, with a bathroom and a smaller family room. In BuildFlow's pricing two bedrooms and a bath at about 1,000 sq ft is $71,000–$82,000.
How much does it cost to finish a 1,000 sq ft basement?
In BuildFlow's pricing, from $53,000–$62,000 for one open family room to $78,000–$90,000 for two bedrooms and two bathrooms, standard finish. A family room, bedroom and bathroom is $66,000–$76,000.
Where should the bathroom go in a basement?
Near the existing drain rough-in or main stack, because trenching the slab for drain lines is the expensive part. Back-to-back bathrooms or a bathroom beside a bar can share drain runs.
Where should a basement bedroom go?
On an outside wall where an egress window can be cut, away from the mechanical room. The window well needs room in the yard and must meet your city's setbacks.
What is the best layout for a basement with a beam down the middle?
Use the beam line as the edge between two zones, like the family room and a bar or play area, and wrap the posts so they look intentional instead of placing them in the middle of the seating.
