Three bedrooms · no garage From the supplied plan.
Three bedrooms · no garage · 2 homes · Retain + add one · Horizontal boards · Truss · COLORBOND
Plan 01: 3 bedrooms, 2 bathrooms, a separate laundry and a 2.7 m flat finished ceiling. This source drawing has no garage.

01 / Three source drawings
Room count and garage choice. One clear source for each plan.
The three supplied plans share a stepped house outline and two bathrooms. One allocates the southeast room to a third bedroom; the two-bedroom versions use that area for living. The garage belongs only to the third source plan.
Three bedrooms or a larger living area
The source third-bedroom wall is retained in the three-bedroom plan. The two-bedroom plans keep that part of the living area open.
Two bathrooms and a separate laundry
Bathroom access and fixtures follow the selected drawing. Both are described as bathrooms; a private bedroom bathroom is not assumed.
Garage in the source position
The first two plans have no garage. The third keeps its left-side garage and the source connection to the entry zone.
Source labels and calculated geometry
The house's dimensioned bounding width and depth are 9.99 × 8.64 m. Its notches and lower wet-area projection mean it is not a full rectangle. The printed source labels are retained separately from the digitised outline and room-area calculations.
This source labels the house including its porch as 78.39 m²: 76.97 m² enclosed plus 1.42 m² porch. It has no garage. Calculated traced footprint and internal areas are recorded separately; reconcile their measurement basis in project documentation.
02 / Select a source plan
Three rooms-and-garage choices.
Plan 01 has three bedrooms and no garage. Plan 02 has two bedrooms and no garage. Plan 03 has two bedrooms and the source left-side garage. All three have two bathrooms and a separate laundry; openings and walls follow each supplied drawing.

Dimension chains are transcribed from the source. Unlabelled positions and furniture are calibrated traces, not surveyed or fabrication measurements. Doors, clearances, ventilation, structure and services need project coordination.
A bedroom, living-space and garage decision.
01 / Three bedrooms · no garage
The southeast room remains bedroom 3, leaving a smaller shared living area. There is no garage in this source drawing.
02 / Two bedrooms · no garage
The third-bedroom area becomes part of the living room. The two bathrooms and separate laundry remain; there is no garage.
03 / Two bedrooms · left garage
The two-bedroom interior is retained with the source garage attached on the left. Garage access, the house connection and its apron need project coordination.
These priorities are design hypotheses for broad appeal. We have not established a Melbourne resale-price premium for any option. Test the preferred plan against comparable settled sales and local buyer feedback.
Living room
Wide eye-level view of the source living seating and its existing openings; do not add a fireplace, study or bedroom.
Living room towards the entry
Reverse view from the living free-space towards the actual entry/circulation; preserve furniture and wall positions.
Kitchen
Show the source L-shaped wall kitchen, sink, hob and fridge in their exact positions. No invented island or peninsula.
Kitchen sink and counter
Close view of the actual sink and surrounding counter; only show a window if the source places one here.
03 / The home belongs to a site
Start at the street. Design all the way to the garden.
Place the selected source house in a retain-and-add or four-home concept setting. Keep the house and its source garage together. The site drawings are geometric placement studies; actual title, north, access and site fit remain unverified.
Concept design · Not for approval or construction
- Development study
- Retain the front home; add one source house
- House bounding dimensions
- 9.99 × 8.64 m
- Garage choice
- No garage in this source plan
- Open space and access
- To site-specific design
Straight driveway study
Changing this strip reallocates hardscape only. It does not certify turning, passing, drainage or pedestrian separation. Dashed routes show intended movement, not a swept-path analysis.
The retained home matters
The retained home is a placeholder. Survey its walls, windows, roof, outdoor space and services before relying on the proposed new-house location.
The garage belongs to plan 03
Keep its source-relative position and house connection. Boundary controls, fire separation, drainage, easements and vehicle access require site-specific design; a drawn garage does not establish a boundary-building permission.
POS is not the garden-area calculation
The marked private outdoor space explains use and dimensions. Garden area, permeable surface, canopy cover and usable secluded space have different definitions and need separate schedules.
Sun first, mirror second
North is not established for this generic lot. Test winter sun and summer shading before fixing the garden-facing openings or choosing a mirrored version.
Retain-and-add arrival
Approach the selected new house past the retained-home placeholder. Keep the actual porch/entry and correct C garage.
Courtyard dining
Outdoor dining in the indicative garden looking back at the source house. Do not invent a sliding door, deck or canopy not in the source.
House and lawn
A close garden relationship showing only the selected source house and nearby lawn; exclude scenario-specific neighbours so it can be reused in both developments.
Sheltered source porch
View the actual west/southwest recessed porch under its own shelter in gentle rain. No added large deck, awning or rear glass wall.
04 / One recognisable face
Quiet architecture. A warm welcome.
The selected source has 3 bedrooms and two bathrooms. No garage is added. White horizontal boards and the selected roof finish follow its stepped outline and fixed openings.
Selected finish: white horizontal fibre-cement boards, warm entry finish and black frames, on the selected source geometry.
Roof option on the selected source plan
A hipped roof with prefabricated trusses and deep-charcoal corrugated COLORBOND steel is shown as a concept option. Ridge and hip caps, external gutters, fascia and soffits require coordinated project design. The indoor ceiling stays flat at 2.7 m.
Roof forms and vertical opening heights are visualisation assumptions. The hipped option shows an indicative 22.5° pitch; structure, bracing, tie-downs, underlay, ventilation, insulation and drainage require the project's coordinated design. Confirm materials and colour with physical samples and the energy assessment.
A geometric view of the selected source outline and openings. Plan 03 includes its source garage; the other plans do not. Door/window heights and roof build-up remain visualisation assumptions.
Drag or swipe to change viewpoint. Arrow keys also work.
A sequence of generated architectural views, not a measured 3D model or Street View capture. Small visual differences may occur between views. Use the drawings for the fixed geometry.
Entry-side elevation / selected source plan
Openings follow the selected drawing. The garage remains in plan 03's supplied relative position. Opening heights, roof assemblies, foundations and construction junctions are visualisation assumptions to coordinate in the project.
White horizontal cladding
A consistent direction and calm joint rhythm make the small building read as one composed volume.
Timber-framed entrance
Warmth is concentrated where you touch and enter the building; the threshold remains legible from the driveway.
Black framed openings
Black frames follow the source opening locations. horizontal heights, glazing performance, daylight, privacy and shading require the project opening schedule.
05 / The everyday experience
The luxury is in the room.
Interior views follow the selected source plan's walls, kitchen, bathrooms, laundry and furniture arrangement. The finished ceiling is flat at 2.7 m; the images illustrate finishes and do not replace the source dimensions.

The selected living room
Keep the source seating and circulation. Plan 01 retains the third-bedroom partition; plans 02 and 03 use that area as part of the larger living room.

The source kitchen and dining
The wall kitchen, sink, hob, fridge and dining table stay in the source positions. Appliance and cabinet details need coordinated project drawings.

Bedroom 1
The bed, wardrobe and window follow the selected drawing. Bathroom access is taken from the source; no private bathroom is added to the bedroom.
AI-generated design study. Materials and proportions are illustrative; the dimensioned plan governs this concept.
2.7 metres, from finish to finish.
The clear height is 2.7 m from finished floor to flat finished ceiling in every source plan. The selected roof sits above the ceiling; structure, insulation, ventilation, lighting and service routes require project design. The roof choice does not create a cathedral ceiling inside.
A separate laundry in every plan.
The source laundry tub and bench remain in the lower service block, reached from the rear hall. The drawing does not identify a washing-machine position; appliance selection, placement and service connections need project coordination.
06 / A disciplined material palette
Fewer materials. Better junctions.
The finish language is fixed; the selected products still need evidence of suitability and a coordinated installation system. Colour, durability and maintenance should be reviewed together.

White horizontal cladding
Fine horizontal rhythm / restrained whiteConfirm board system, cavity, fasteners, flashings, coating warranty and boundary suitability. The image does not nominate a tested product.
Warm timber at the entry
Concentrated warmth / sheltered locationChoose timber or an approved timber-look system after fire, weather exposure and maintenance checks. Resolve end grain and drainage.
Black aluminium frames
Clean outlines / consistent opening headsWindow performance, glazing, seals, installation and shading are specified to the climate and final energy model.
Quiet interior surfaces
Light walls / tactile joinery / calm floorUse a coherent finish schedule. Check wet-area transitions, slip resistance, durability, low-emission selections and replacement access.
Interior material palette
One composed material study using the newly rendered interior palette: light oak, warm neutral joinery, off-white walls and pale stone. No exterior roof or cladding in view.
Joinery corner
Source kitchen joinery corner and bench junction; preserve the source wall kitchen, no island.
Wet-area finish detail
Source bathroom wet-area material/threshold study; no product certification or unshown construction claim.
Flat ceiling and wall junction
Source living wall meeting the flat 2.7 m finished ceiling, subtle light and a local junction detail. No cathedral ceiling, roof frame or exterior roof in view.
07 / Repeat the intelligence, adapt the interfaces
Designed to travel across different blocks.
The first version is a rear addition. Future projects can borrow its spatial logic without pretending every site is identical. Preserve what creates the experience; redraw what connects the home to the ground and neighbours.
| Situation | Keep | Adapt |
|---|---|---|
| Three bedrooms without a garage | Source bedroom-three partition and all openings | Site access, parking and outdoor space |
| Two bedrooms without a garage | The source larger living area and two bathrooms | Orientation, access, services and landscape |
| Two bedrooms with the source garage | The attached left garage and its house connection | Vehicle route, fire separation, drainage and boundary details |
| Sloping ground | Source rooms and 2.7 m flat ceiling target | Foundations, levels, access and retaining |
| Four homes | Each selected source house and its garage relationship | Lot layout, shared access, turning, gardens, services and titles |
| Restricted construction access | The selected final source layout | Panelisation, lifting and local assembly strategy |
A repeatable product is a coordinated kit of decisions. It is not a promise that the same permit, roof detail or footing can be copied from one site to the next.
08 / From an image to a buildable package
A common brief for both sides of the supply chain.
Use this manual to agree the experience and the interfaces. Manufacturing release comes later, after the Australian design, engineering, building-surveyor review and inspection programme are coordinated. The concept is not a fabrication instruction.

Survey & datums
Surveyed title boundary, levels, easements, services and one agreed set-out datum. Establish the relationship between finished floor and the existing driveway.
Structure & foundations
Engineer-designed load path, bracing, footings, transport loads, connection tolerances and lifting points. No module joints are frozen by these images.
Openings & joinery
Number the source openings and cabinets. Coordinate clear openings, hardware, appliance sizes, furniture clearance and maintenance access before production.
Wet areas
Agree waterproofing system, falls, thresholds, penetrations, drainage, ventilation and inspection hold points before walls and floors are concealed.
Envelope & condensation
Confirm the complete wall and roof assembly: cavity, membranes, insulation, flashings, window installation, airtightness and condensation strategy.
Services & energy
Coordinate electrical supply, hot water, heating/cooling, exhaust, sewer, stormwater and maintenance zones. Confirm appliance and drinking-water product conformity.
Garage & roof junction
Resolve the independent garage access, boundary wall, fire separation, roof movement, flashing and gutters within the title. Avoid hidden maintenance traps.
Evidence & handover
Maintain product evidence, approved revisions, factory and site inspections, as-builts, commissioning, manuals, warranty boundaries and a defects process.
Four release gates
01 / Concept agreed
Select the plan, area basis, facade language and project priorities.
02 / Site coordinated
Survey, approvals, access, services and consultant design resolve the real lot.
03 / Production released
Issue controlled drawings, specifications, product evidence and inspection points.
04 / Installed & verified
Complete site connections, inspections, commissioning and required occupancy documentation.
Design coordination table
Generic tabletop coordination scene grounded in the selected new plan. Use the actual source plan as a small reference sheet, no invented dimensions or legible AI text, no facade or finished roof in view.
Wall-panel assembly
Selected plan wall-panel assembly on a generic workshop jig, unbranded and unfinished. No completed exterior, no roof-family-specific trusses or installed roof.
Wet-area inspection stage
Selected plan bathroom-one fixtures and substrate at an inspection stage; preserve fixture locations. Generic process illustration, no inspector endorsement or invented certification.
Protected panel delivery
Protected wall-panel bundles for the selected plan with unfinished backing visible; no finished cladding direction, completed facade or roof-family-specific material in view.
09 / The route is part of the design
A driveway for a car is not a delivery plan.
A 3–3.5 m side driveway is a useful starting condition for daily access. A truck, a finished module and a crane each need a different study. Choose the construction method after checking the route and site.
Panel or material kit
Smaller elements may suit constrained access. More assembly and weather management happen on site; connections and inspection stages need clear instructions.
Finished modules
Move more fit-out into the factory when route, load dimensions, lifting and temporary stability allow. A narrow driveway does not by itself confirm or rule out a crane solution.
Local assembly
Retain the same design language with a site-built strategy when access, terrain or economics favour it. Delivery choices should serve the final home.
Before the delivery method is fixed
- Street approach, load envelope and route permissions
- Overhead wires, trees, neighbouring structures and sightlines
- Crane standing area, reach, lifting weight and ground bearing
- Protection of the retained home and its daily access
- Temporary storage, weather protection and installation sequence
10 / One design, different decisions
A shared starting point.
For future residents
Compare bedroom count, living space, the two bathrooms, separate laundry and whether you need the source garage. Choose the plan that fits your daily routine.
Compare the plansFor manufacturing partners
Discuss repeatable details, fabrication tolerance and inspection evidence early. The shell is a starting system; transport splits, foundations and roof junctions are resolved per project.
Read the factory briefFor development partners
Assess title constraints, approvals, acquisition, site works, services, delivery and exit together. Distinguish dwelling numbers from separately saleable titles. No price, rental or return forecast is implied by the concept.
Review the site assumptionsWhat we would test with Melbourne buyers
Test the selected room and garage arrangement with local residents, agents and settled comparables matched for location, date, title, condition, size, parking and outdoor space. No resale premium is established by these design illustrations.
11 / A closer look
One design family. Every perspective.
The reviewed image set follows the selected source plan, development, cladding and roof. Interior and process images are shared between roof options only where no exterior roof or cladding is shown.

Questions worth resolving early.
Is this a permit-free granny flat?
No permit-free claim is made. This concept is designed as a full second dwelling and is not presented as a small second dwelling. Since Amendment VC306 (15 October 2026) that planning category covers 80 m² or less total floor area measured to the outside of the external walls, while the Building Regulations still define it as 60 m² or less; this concept's statutory floor area, including any attached garage, must be measured separately. A retained-home plus new-dwelling proposal needs its own planning and building pathway; GRZ with no overlay is not automatic approval.
Will a 3.5 m driveway avoid a traffic-engineer request?
No width guarantees that outcome. The entire route, garage opening, turning area, gradients, parking provision and pedestrian conditions need to work together. A council can request evidence where it needs it. Obtain a scaled swept-path assessment for the actual layout when required.
How are the source house and garage areas recorded?
This source labels the house including its porch as 78.39 m²: 76.97 m² enclosed plus 1.42 m² porch. It has no garage. Calculated traced footprint and internal areas are recorded separately; reconcile their measurement basis in project documentation.
Can the garage touch the boundary?
Only plan 03 includes the source left-side garage. Its drawn relationship does not establish permission to build on a boundary. Survey, fire, openings, eaves, gutters, easements and maintenance require project review.
Which plan includes a garage-to-house connection?
Plan 03's source drawing shows a connection from the garage to the entry zone. Plans 01 and 02 have no garage. Door construction, fire separation, ventilation and access must be resolved for the project.
Which plan has a third bedroom?
Plan 01 has three bedrooms and two bathrooms without a garage. Plans 02 and 03 have two bedrooms and two bathrooms, with more of the southeast area used for living. Plan 03 also includes the source garage.
Are the images and drawings ready for construction?
No. The drawings are dimensioned concept studies and the generated images illustrate design intent. Fabrication requires the project’s coordinated architectural, structural, services, product and approval package.
Can this become a four-home development?
The design family can inform a four-home scheme. The illustrated second scenario is a massing study, with new site-level decisions for entries, parking, gardens, trees, services and title strategy. It is not a four-dwelling approval or subdivision conclusion.
