Imagine a Melbourne homeowner comparing two granny flat concepts. The first keeps almost all of the available floor area indoors. The second adds a full-width covered verandah outside the living room, creating a sheltered place for morning coffee and family visits.
The verandah looks like bonus space. Then the design is checked more closely. Its roofed area affects the small second dwelling floor-area calculation, the roof shades the living room in winter, and the posts reduce the clear path beside the building. The feature may still be worthwhile, but it is no longer a free addition.
A granny flat with a verandah can feel larger, more welcoming and better connected to the backyard. The decision should begin with how the space will be used and how it fits the property, not with the facade alone.
What is a verandah in a granny flat design?
In everyday Australian use, a verandah is a roofed outdoor area attached to a building. It may sit across the front, outside the living room, along one side or around a corner. The floor could be timber decking, concrete or another external finish.
The words verandah, deck, porch and alfresco are often used loosely in marketing. For design and approval work, the physical elements matter more than the label:
- Is the area roofed?
- Is it structurally attached to the dwelling?
- Does it have posts, walls, screens or balustrades?
- How high is it above the ground?
- Does it form part of the entry or an accessible path?
- How will roof water be collected and discharged?
These questions affect measured area, siting, structure, drainage and the work that needs to appear in the drawings and quotation.
Does a roofed verandah count towards Victoria's 60 m² limit?
This is where homeowners need to be careful with interstate advice.
The current Victorian Building and Plumbing Commission guidance states that the 60 m² total floor area of a small second dwelling is measured from the outside of external walls or the centre of party walls and includes all roofed areas.
That means a roofed verandah associated with the small second dwelling needs to be considered when the total area is calculated. A concept showing 60 m² of enclosed rooms plus an additional roofed verandah should not be assumed to fit the Victorian small second dwelling definition.
An unroofed deck or paved outdoor area raises a different set of questions. It should not automatically be treated as unrestricted space. Height, structure, siting, garden area, drainage, building-permit requirements and property controls may still be relevant.
The current Planning Victoria siting guidelines also treat a verandah as a building when calculating site coverage in the examples. Check the MPLUS Granny Flat Rules Victoria guide for the broader framework, but use current official and property-specific advice before relying on any area calculation.
Start with the job the verandah needs to do
A verandah should solve a real daily-use problem. If its only purpose is to make the front elevation look more complete, the same space and budget may be more useful elsewhere.
Common functions include:
- sheltering the front door from rain
- shading large living-room glazing in summer
- providing an outdoor dining or sitting area
- creating a transition between the home and garden
- protecting a level or gently graded entrance route
- giving the resident a private outdoor zone separate from the main house
List the intended furniture and activities. A narrow strip may protect a doorway but not accommodate a chair safely. A deeper verandah may support dining, yet take more roofed area and shade more of the interior. The design becomes clearer when the purpose is specific.
The broader MPLUS Design collection can help compare floor plans, but the outdoor area should be reviewed as part of the plan rather than added after the rooms are fixed.
Four verandah arrangements to compare
1. A compact entry verandah
A small covered entry can protect the door, provide a place to pause and make the granny flat easier to identify from the access path. It uses less area than a full-width structure and may have less effect on living-room daylight.
It is not automatically the best option for outdoor living. Check whether the entry remains clear when a visitor arrives, the door opens and a resident moves through with shopping or mobility equipment.
2. A living-room verandah
Placing the verandah outside the main glazing can create a strong connection between the living room and garden. Sliding or stacking doors can make the two zones feel related when weather permits.
The main trade-off is light. A deep roof on the wrong orientation can leave the living room dark, particularly when the main house, a fence or trees already reduce sunlight. Model summer shade and winter sun before choosing the roof depth.
3. A side verandah
A side verandah can combine sheltered access with a narrow outdoor sitting area. It may suit a granny flat where the resident enters along the side of the main house.
However, it can consume valuable clearance beside the dwelling. Posts, gutters and furniture should not obstruct pedestrian access, service equipment or maintenance routes. Privacy also needs attention if the verandah faces windows in either home.
4. An unroofed deck or paved terrace
Where the 60 m² roofed-area calculation is tight, an unroofed outdoor zone may preserve more enclosed floor area. It can provide a direct garden connection without shading the main glazing as heavily.
This option offers less weather protection. It also still requires review of levels, drainage, structure, thresholds, siting and approval requirements. It is an alternative to test, not a loophole.
Orientation determines whether shade helps or hurts
A verandah can improve summer comfort by shading glass. The same roof can reduce useful winter sun if its depth and orientation are poorly matched to the site.
Consider:
- where the sun reaches the building in winter and summer
- whether nearby houses, fences or trees already create shade
- the direction of prevailing rain and wind
- which side has the best garden outlook
- whether outdoor use will disturb bedrooms in either dwelling
- where evening lighting will face
A west-facing verandah may need a different response from a north-facing one. Roof depth, side screening, planting and window placement should work together. Avoid choosing a standard verandah and rotating it around the plan without rechecking light and weather exposure.
Privacy matters on both sides of the outdoor area
Outdoor seating changes where people spend time, talk and look across the property. A verandah that faces the main home's kitchen or deck may make both households feel observed. One placed close to a neighbour's windows may need a different orientation or more considered screening.
Privacy does not always require a solid wall. The design may use:
- a change in angle
- partial screening at one end
- planting outside the circulation path
- a lower viewing direction towards private garden
- careful placement of doors and seating
- separation from bedroom windows and heating or cooling equipment
Heavy screening can reduce daylight and ventilation, so it should be tested with the indoor plan. The MPLUS Land Eligibility Check helps frame this as a whole-property question rather than an isolated facade choice.
Drainage and thresholds need early coordination
A verandah adds roof water, edges, junctions and external levels. These details are less visible in a concept image but can strongly affect performance and cost.
The drawings should resolve:
- roof fall, gutters and downpipes
- where collected water will discharge
- the junction between the verandah roof and the dwelling
- deck or paving fall away from doors
- the threshold between inside and outside
- steps, ramps or balustrades where required
- termite, moisture and ventilation details relevant to the selected construction
Adding the verandah late can force changes to doors, footings, stormwater work and external levels. It may also create a threshold that is less convenient for an older resident or someone using a mobility aid.
The MPLUS How We Build guide explains why design, approvals, factory or site work and final installation need to be coordinated as one project sequence.
What should the verandah quote include?
Do not compare one quotation that includes a completed verandah with another that only shows the main dwelling shell.
Ask whether the scope includes:
- design and engineering
- footings, posts, beams and roof structure
- roofing, flashings, gutters and downpipes
- decking, slab or paving finish
- steps, ramps, handrails or balustrades where required
- external lighting and electrical work
- painting, sealing and edge details
- drainage connection and ground preparation
- reinstatement of disturbed landscaping
A verandah can be useful without being elaborate. The cost question is whether its function justifies the roofed area and complete installed scope. The MPLUS Granny Flat Cost Victoria guide explains why an attractive concept feature should be assessed within the full project budget.
A practical verandah decision table
| Homeowner priority | Option worth testing | Main risk to check |
|---|---|---|
| Weather-protected entry | Compact entry verandah | Door, landing and path clearance |
| Outdoor dining | Living-room verandah | Roofed-area allowance and furniture depth |
| Summer shade | Verandah over main glazing | Loss of winter daylight |
| Private outdoor space | Garden-facing verandah with selective screening | Overlooking and reduced ventilation |
| Preserve enclosed floor area | Unroofed deck or paved terrace | Weather exposure, levels and approvals |
| Narrow access side | Small entry canopy or no side verandah | Posts, gutters and service access |
Plan the verandah with the property, not after it
A verandah can make a compact granny flat more comfortable when it provides useful shelter, a clear entrance and a private connection to the garden. It can also consume roofed area, shade the interior, complicate drainage and take space from the access path or backyard.
The right answer depends on the resident, the orientation and the usable part of the land. Before locking in a roofed outdoor area, send MPLUS your property address through the Free Land Check. We can review the available space, access and obvious planning or site constraints before the verandah and floor plan are finalised.
