An 11 by 11 meter footprint delivers about 121 square meters per floor, roughly 1,300 square feet, which is enough for three bedrooms plus the usual living spaces without the waste that creeps into larger plans. House plans at this size stay popular because they fit standard lots, keep construction simple, and leave room in the budget for better finishes. The layout strategy that makes them work is the same one found in open floor plans: fewer interior walls, shared circulation, and rooms that borrow space from each other. The 11 by 11 plan works as a single story on a wide lot or as a two-story version on a narrow one, which is why the same footprint shows up in so many regional styles.
This article breaks down a three-bedroom plan room by room: zoning, bedroom sizes, bathrooms, ceiling treatments, and the lot and code checks that turn a generic plan into a buildable one.
Zoning the Plan Into Private and Shared Spaces
The first decision in a three-bedroom plan is where the private wing sits relative to the shared wing. Placing the bedrooms on one side of the house and the living, dining, and kitchen on the other gives a clear separation between noisy daytime zones and quiet sleeping areas. Plans with strong indoor-outdoor floor plans extend that logic to the site, aligning the shared wing with the terrace or garden so the busiest rooms open to the outdoors.
Bedroom Wing Placement
- Put bedrooms away from the street and the garage to cut noise at night.
- Orient bedroom windows to the east or north for soft morning light and lower heat gain.
- Place the bathroom between the bedrooms to shorten nighttime circulation.
Shared Wing Placement
- Face the living and dining zone toward the garden, terrace, or best view.
- Keep the kitchen near the entry for short grocery-carrying paths.
- Locate the laundry near the bedrooms or the bathroom rather than in the garage.
Circulation is where small plans waste space. A hallway wider than 1.2 meters, a foyer that serves only one door, or a kitchen with two separate eating areas can eat 10 to 15 square meters of a 121 square meter floor. Merge corridors into rooms where possible: a living room that doubles as the passage to the bedrooms saves area without sacrificing privacy.
Sizing Bedrooms and Common Areas Realistically
Room sizes decide whether a plan feels generous or cramped, and the numbers are easier to get right on paper than after the foundation is poured. The sizing discipline used in small house plans applies here: give each bedroom a minimum that fits real furniture, then spend the remaining area where the family actually lives.
Bedroom Size Targets
| Room | Minimum size | What fits |
|---|---|---|
| Master bedroom | 3.6 x 3.6 m | Queen bed, en-suite, walk-in closet |
| Second bedroom | 3.0 x 3.3 m | Double bed, wardrobe, desk |
| Third bedroom | 2.7 x 3.0 m | Double or twin beds, wardrobe |
| Living room | 4.5 x 4.0 m | Seating for six, media wall |
| Kitchen and dining | 3.6 x 3.0 m | Galley or L-shaped kitchen, table for four |
Sizing to real furniture matters more than chasing generous numbers. A 3.0 by 3.3 meter second bedroom fits a double bed, a 600 millimeter wardrobe, and a desk only if the door swing and window placement are checked against the furniture layout. Draw each room with the actual pieces in plan before the foundation is poured.
Flow Between Living and Kitchen
The living room should stay open to the kitchen because that connection carries most family activity. A breakfast bar or peninsula keeps the cook in the conversation, and a clear sightline from the entry to the rear window makes the whole floor feel larger.
Furniture clearances that prevent regrets
- Leave 90 to 100 centimeters of walkway in front of kitchen counters.
- Allow 45 centimeters between the sofa and the coffee table.
- Keep a 60 centimeter clearance on the hinge side of bedroom doors.
Bathroom Placement and Guest Convenience
A three-bedroom house needs at least two bathrooms: an en-suite for the master and a shared bathroom for the other bedrooms and guests. Layout traditions borrowed from farmhouse style plans, where the bath sits close to the bedrooms and the back door, solve both convenience and the muddy-boots problem at once.
En-Suite Versus Shared Bathrooms
- Master en-suite: a compact 1.8 by 2.4 meter bathroom with shower, vanity, and toilet preserves privacy.
- Shared bathroom: place it in the hall between the two remaining bedrooms so neither bedroom walks through the other.
- Guest access: a powder room near the entry saves guests from crossing the whole house.
Plumbing Efficiency
- Group the bathrooms back-to-back or stacked to share a single wet wall.
- Keep the wet wall short so hot water arrives quickly at every fixture.
- Vent each bathroom to the outside through a common duct where possible.
- Specify water-saving fixtures: 6 liter toilets and 6 to 9 liter per minute showerheads.
Bathroom count also affects resale. Real estate data consistently shows that a three-bedroom home with two full bathrooms sells faster and at a higher price per square meter than the same plan with a single bathroom, which makes the second bathroom a sound investment even when the budget is tight.
Ceilings and the Perception of Space
Ceiling height changes how a room feels more than any single finish. Vaulted ceilings over the living and dining zone add volume where people gather, while the bedrooms keep standard 2.4 meter ceilings for simpler framing and lower heating costs.
Where a Vault Ceiling Pays Off
- Living and dining zone: a vault over 4.5 meters of span makes the room feel twice its size.
- Entry and hall: a small volume of vertical space at the front door creates arrival drama.
- Bedrooms: keep them flat; vaults there waste heat and complicate wardrobes.
Structural and Cost Notes
Vaulting a ceiling means exposing the roof structure or adding a scissor truss, which costs more than a flat ceiling and reduces the attic space available for storage. Balance the visual gain against the lost loft and the extra framing.
The cost difference is easy to underestimate. A scissor truss or exposed rafter ceiling adds roughly 5 to 8 percent to the roof framing budget, and it changes the HVAC layout because the conditioned volume grows. Most builders recommend vaulting only over the shared zone and keeping the rest of the plan at standard height.
Adapting the Plan to Your Lot and Local Rules
A plan is a starting point, not a final product. The lot’s shape, slope, and orientation, plus local building codes, set the real constraints, and single story design principles, such as keeping the plan wide and low, apply when the site allows only a modest footprint. On a narrow lot the same three-bedroom program stacks into two stories instead.
Lot Checks Before You Commit
- Measure the buildable area after setbacks, easements, and driveway requirements.
- Check the slope; a 1 to 2 percent site slope is easiest, while steeper sites push costs up.
- Confirm the floor elevation against flood and drainage requirements.
- Verify solar orientation for the living wing and any planned panels.
An orientation flip costs nothing on paper. Rotating the plan 90 degrees can change annual heating and cooling demand by 10 to 20 percent in some climates, because the long facade faces the sun instead of the street. Check the solar path before finalizing the window schedule.
Code Items That Change the Plan
- Minimum bedroom window size for emergency egress.
- Stair width, riser, and tread limits on two-story versions.
- Minimum ceiling heights and insulation values for your climate zone.
Furnishing and Finishing a Three-Bedroom Home
The third bedroom is what makes this plan flexible. It works as a guest room, a home office, a nursery, or a storage room, and the finishing should stay neutral so the room can change jobs. Villa style layouts show how flexible rooms stay elegant: simple wall treatments, durable floors, and built-in storage that does not dictate a single use.
Making the Third Bedroom Multifunctional
- Install a wall bed or a sofa bed so the room doubles as an office.
- Add a deep closet with adjustable shelving for storage-heavy uses.
- Run network and power outlets to the desk wall.
Finishing Touches That Protect the Investment
- Choose floor finishes that resist the main wear path: tile or wood-look flooring in the entry and kitchen.
- Paint walls in light neutral tones that work with any future furniture.
- Add a home-run data panel so network changes never require opening walls.
- Keep exterior cladding maintenance-free so the house stays presentable for resale.
The plan works best with a small service zone for the items that never fit inside: bicycles, garden tools, and seasonal decorations. A 6 square meter storage room off the entry, or a compact garage wing, keeps the three bedrooms and living spaces free of clutter for the life of the home.
A three-bedroom plan succeeds when every room can do more than one job. The en-suite and the shared bath handle the daily routine, the open living zone absorbs gatherings, and the third bedroom adapts as the household changes. That flexibility is what keeps an 11 by 11 footprint from feeling small after a few years of occupation.
