Houses introduce three things apartments cannot have: a garage, a chosen hallway style, and a 1-to-5 bedroom range that crosses two design eras. A 1-bedroom house and a 5-bedroom house are not the same building scaled — they have different circulation logic, different room hierarchies, and different relationships between public and private zones.

How this generator works

The house generator uses a grid-based room-placer (engine v3) with adjacency scoring rather than the template-based approach used for apartments. The placer first establishes the building envelope and shape (rectangle, L, T, or U), then places rooms by priority: living first (largest public zone), then kitchen adjacent to living, then bedrooms grouped, then bathrooms next to bedroom clusters, and the garage as a single rectangle at the entry side if enabled. Hallway style affects circulation: 'central' creates a backbone hall, 'l-shaped' turns the corridor once between zones, and 'minimal' eliminates the hall in favour of room-to-room flow. Doors are placed by rule: living to entry, kitchen to dining, bedrooms to corridor, bathrooms to bedrooms or corridor.

Design principles for houses

House bedrooms scale with house size — at 80 m² total a 2BR house has bedrooms in the 9–12 m² range, but at 250 m² a 4BR house has bedrooms in the 13–20 m² range and the master often gets a walk-in. Living rooms are 20–45 m². Kitchens 8–15 m². Garages, when included, take 18–22 m² for a single-car and 32–42 m² for a double-car configuration. Houses typically allocate 8–12% of total area to circulation (corridors, foyer, stair if multi-level), apartments allocate 5–9% — the difference is what makes a house feel less compressed.

When the house generator fits

Single-family detached homes, ADU and granny-flat plans at the small end (60–90 m², 1BR), suburban family homes in the middle (130–200 m², 3–4BR), and larger custom builds at the upper end. The grid-placer engine is best suited to rectangular and gently-modified envelopes; for highly irregular sites, the L/T/U shapes are an approximation rather than a precise fit, and a real architect's plan will outperform the generator on edge cases.

Configuration tips

Garage adds value most clearly at 120+ m² with 3+ bedrooms — below that the garage eats family-room area. Hallway style 'minimal' works at small sizes (1–2BR) where the open layout is honest about a small footprint; 'central' works at 3+BR where wayfinding matters; 'l-shaped' is the in-between option. Ensuite is offered at 2+BR and is most useful at 3+BR. Dining room is a separate enclosed space and only appears at 100+ m²; below that the dining zone is part of the kitchen or living envelope.

Frequently asked questions

How does the house generator differ from the apartment generators?+

Apartments use a template-based engine with hand-crafted layouts per bedroom-bathroom combo. The house generator uses a grid-based room-placer with adjacency scoring — it places rooms by priority (living first, kitchen adjacent to living, bedrooms grouped, baths near bedrooms, garage at the entry side) rather than picking from a template catalogue.

Can I add a garage to my house plan?+

Yes. The garage toggle adds a single rectangle at the entry side of the building when enabled. Single-car garages occupy 18–22 m², double-car around 32–42 m². The garage is most space-efficient at 120+ m² total area; below that it eats family-room area.

What hallway styles does the house generator support?+

Three: 'central' creates a single backbone hall, 'l-shaped' turns the corridor once between zones, and 'minimal' eliminates the corridor in favour of room-to-room flow. Minimal works at small sizes (1–2BR); central works at 3+BR where wayfinding matters.

Are these house plans suitable for actual construction?+

No. The plans are for inspiration, real-estate listings, ADU exploration, and pre-architect visualisation. They do not include structural walls, fire-egress paths, accessibility-mandated circulation widths, or any jurisdiction-specific code compliance. Do not build from a generated plan — engage a licensed architect or engineer.

They reflect common ranges from residential building practice; specific jurisdictions (ANSI Z765 in the US, Approved Document M in the UK, NCC Volume 2 in Australia, and equivalent codes elsewhere) impose their own minimums and accessibility requirements.
