A home concept, inside and out

Start with a description or draw in the studio. Explore the tools below, then check the design options that matter to your idea.

Create and arrange

Generate a home from a brief, create a floor plan, or try room layouts and finishes.

Explore the whole home

Plan kitchen counter arrangements, several floors, and outdoor space. Then walk through the result.

Use familiar measurements

Switch between metres and feet to read room sizes, enter dimensions, and measure distances. The PDF follows your choice, while model files keep their metric units. Work in metres or feet.

Keep and share your work

Save your design, bring in other people, and choose a download format.

What you can request from the AI

Rooms and floors

Describe the rooms you need across up to three above-ground storeys and a basement. The basement can contain up to six rooms. Generated layouts use rectangular rooms, with stairs connecting levels. The floor-to-floor storey height comes from your brief (a stated ceiling height plus the slab), from the storey-height chooser in the Generate panel, or from your region's preset: 2.9 metres in the US and Australia, 3.05 in Pakistan and India, 3.3 in the Gulf, 3.0 in Turkey, 2.8 in Europe. Plans made before this release stay at 2.6 metres, the stair run follows the height, and a revision keeps it unless you ask for another.

Room widths, depths, and target areas describe inside space. Check the delivered measurements and result notes for adjustments. Understand room sizes and wall thickness.

Plot and direction

Specify plot sides from 4 to 120 metres and an entrance facing north, east, south, or west. Identify shared-wall boundaries. Where a declared side or rear boundary is within 2 metres of the house, the generator keeps windows and balconies off that side.

Roof and outdoor structures

Choose a flat, shed, or gable roof. Request front or back porches and verandas, or a front carport for up to three cars. Fit depends on the available space. Porches project from the facade; a recessed porch is built projecting.

Balconies, terraces, and a courtyard

Request balconies from upper-floor rooms with outside walls, or a flat rooftop terrace with stair access. An upper floor can also step back on the front, back, or left to create a terrace. Compare balconies and terrace types.

One central courtyard or lightwell can be surrounded by galleries. It requires a flat roof and cancels a rooftop terrace. It needs a house about 9.5 metres wide (7.5 single-storey): on a narrower plot the generator does not build it and says so, and the rooms take daylight from the front and rear. The house deepens by the court, and the result states the built floor area of every level, the court's open-to-sky area and the share taken by halls and galleries. Parking comes first: when a carport and the court cannot both fit the plot, the court is built shallower (down to 2.4 metres) and the rooms give up to 15 per cent of their area before a back veranda yields, and the court is dropped only when parking cannot fit beside any court, with the reason. A small court takes a small pond. An ensuite beside the court that cannot reach a usable size is built as a shared bathroom and the result says so. Front or back step-backs also require a flat roof and cancel a rooftop terrace. Work through a courtyard-home brief.

Instead of an open courtyard you can ask for a central stair hall — an atrium: the courtyard roofed, with the staircase standing in it. The ground floor is a hall that the stair rises from; above it the well is open through every storey, and the galleries around it become the landing ring, with rails and openings onto the well. The house then needs no stair core on its right side, the roof stays whole over the hall, and a pitched roof is built as asked. One central void per house: a courtyard open to the sky or an atrium, never both. The hall's width is set like a courtyard's and needs the same house width; its depth is the stair's run. It needs two or more storeys and no basement, takes no upper-floor step-backs or rooftop terrace, and is left out with the reason on narrow or serial plans and where parking must fit. The well is roofed and not lit from above: there is no skylight. Plan floors and stairs.

Interiors

Request wall colors such as warm-white, sage, clay, navy, or charcoal, and wood, light-wood, tile, or stone floors. Add furniture wishes, kitchen counter arrangements, arched openings, or decorative columns.

Yard and slope

Ask for planting and water features around the house. Describe a sloping lot for a suitable walk-out basement concept. The slope must be sufficient; otherwise the basement remains buried and the result explains the shortfall.

Supported requests still need room to fit

Furniture, kitchen arrangements, window preferences, and yard positions depend on the layout. Review the result notes to see what was included, changed, or left out.

For generated stairs, an L-turn request becomes a U-turn. An open staircase standing in a central hall is built as an atrium: the flight stands in the hall and the galleries above become its landing ring; an open-stair request without such a hall becomes straight stairs in the stair core. Those changes are disclosed. The manual editor has additional control over these variants.

Understand the detail in your concept

Material choices

Try colours and finishes to develop the feel of your rooms. A declared construction system also provides information for the model and reports, with assumptions that you can review.

Walls and a visible frame

Generated homes generally use exterior walls 0.23 m thick and partitions 0.115 m thick. Room sizes are inside measurements; plot and building dimensions describe the outside. Walls along RC-frame beam lines can be thicker.

A reinforced-concrete frame can include columns and beams as modelled members, with brick infill. The columns stand on a column grid set from the ground floor and run continuous from their footings to the roof they carry; a beam runs on every grid line. Rooms are fitted to the grid: a room may give up to 10 % of its asked area to sit on a line, a short wall return may conceal a column, and a column may stand free in a room — the result says which. A follow-up keeps the columns where they stand unless you ask to re-plan them or to resize the house; a resized house is re-planned, columns included, and the result says so. Their sizes are indicative, never an engineered design. See the frame in Explore and understand its report.

For an RC-frame plan, a preliminary RC member design can be computed on demand: the slab panels, beams, columns and footings are sized by a stated method under the regional practice, with the brief's soil bearing, grades, founding depth, water table and seismic zone printed with their source. It is gravity-only and indicative, never an engineered design or a safety sign-off, and it is not a bar-bending schedule; an engineer designs and signs. Read the RC design report.

Plans, images, and quantities

Download a dimensioned PDF plan, save a high-resolution image, or choose an editable file or model for the next conversation.

An indicative bill of quantities helps you review materials, assumptions, and allowances. It contains quantities only, not a cost estimate.

Read the result alongside your brief

Keep your essential requirements visible while you review the rooms, routes, and outdoor spaces. A revision keeps the house outline unless you ask to resize it: rooms you add share the existing space, and a change that cannot fit is declined with the reason. Review, revise, or ask to resize the house.
