Nineteen of the 46 home designs we can build are drawn for a 12.5m frontage, more than for any other width. Fourteen of them are four-bedroom homes and five are three-bedroom, and every one has two bathrooms and a double garage. If the lot you are looking at measures 12.5m across the street front, this is the full list of what fits.
It is also the width you are most likely to be offered. As at 20 October 2026, 11 of the 30 house and land packages on our books that record a frontage sit on a 12.5m lot, on blocks from 313m² to 441m², and six of those eleven blocks are 375m². No other frontage comes close on our list.
So the useful question at 12.5m is rarely “will it fit?” It is “which of the nineteen suits the way we live?” That comes down to a handful of choices: a theatre or not, a scullery or a walk-in pantry, where the master suite sits, and whether the kids get their own wing.
All 19 designs at a glance
Floor areas are the figures published on each design’s page. Where a design does not publish one, the column says so rather than guessing.

If you want a theatre
Ten of the fourteen four-bedroom designs at 12.5m have a dedicated home theatre: The Avon, The Butler’s Pantry, The Legacy Ridge, The Monolith, The Sculpted Coast, The Beacon Hill, The Lookout, The Landmark, The Grandstand and Kings Park.
That makes a theatre close to standard at this width, so it is worth asking whether you want one before it ends up on the plan by default. A theatre is a fourth living space. If what you actually need is somewhere to work, two designs give you that as a separate room: The Monolith has a dedicated study alongside its theatre, and The Grandstand has a home office as well as a theatre. The Legacy Ridge takes a different line, with a flexible fifth room that can be a study, a guest room or a play room.
If the kitchen matters most
Kitchens are where the 12.5m designs differ most. Four have a scullery, the room behind the kitchen where the mess goes:
- The Butler’s Pantry builds the whole design around a hidden scullery.
- The Swan puts a scullery behind an island kitchen that looks over the living area.
- The Beacon Hill has a scullery and a walk-in pantry.
- Kings Park has a scullery with direct access to the laundry, plus a walk-in pantry.
Three more have a walk-in pantry without a scullery: The Sculpted Coast, The Maker and The Grandstand. If you are weighing one against the other, our page on the difference between a butler’s pantry and a scullery sets out what each room is for.
If you want the kids at a distance
Five designs separate the children’s bedrooms from the master on purpose:
- The Landmark has a separate kids’ wing and keeps it independent of the master suite.
- The Maker has a dedicated kids’ wing.
- The Lookout has a defined kids’ wing, arranged around a central courtyard.
- The Zenith groups the minor bedrooms into their own wing and puts the master at the front.
- The Grandstand has a separate kids’ or guest wing with its own bathroom and soaking tub.
Master at the front or the back?
Most of the 12.5m designs put the master suite away from the minor bedrooms, but they disagree on where. The Zenith, The Beacon Hill, The Breakaway and The Darling Range put it at the front of the home. The Stillwater and The Southern Cross keep the living areas at the rear, away from the street.
Neither is right in itself. A front master is quieter from the kids and the living areas. A rear living zone gets you away from the street and onto the alfresco. Which way the block faces often settles it, because you want the living areas, not the master, catching the northern light. Our guide to which way your house should face on a Perth block covers that.
Why choose a three-bedroom design on a 12.5m lot
Five of the nineteen are three-bedroom homes: The Stillwater, The Foreshore, The Breakaway, The Foundation Stone and The Darling Range. Three of them publish their floor area, and all three are smaller than any four-bedroom design here that publishes one, from 149m² for The Stillwater to 158m² for The Breakaway.
That is the reason to look at them. You get the width of a 12.5m lot without the floor area of a four-bedroom home, which suits a couple, downsizers, or a buyer who would rather spend on the finish than on a room that sits empty. If you need four bedrooms, start with our list of four-bedroom home designs in Perth instead, which also covers the four-bedroom designs drawn for 10m and 10.5m lots.
Five checks on the lot before you choose a design
A design drawn for 12.5m only works on a lot that genuinely gives it 12.5m to work with. Check these before you sign for the land.
- The exact frontage. Read it from the plan of subdivision or the land sale contract, not the brochure. Of the packages on our books as at 20 October 2026, five sit on lots recorded at 12m or 12.1m. Those are not 12.5m lots, and a design drawn for 12.5m has to be checked against them rather than assumed to fit.
- The depth and the block size. Two 12.5m lots can be very different blocks. On our current list, 12.5m lots run from 313m² to 441m², and the depth decides how much backyard is left once the home is on it.
- The R-Code. Setbacks, site cover and open space for a single house come from the state’s Residential Design Codes, published by the WA Department of Planning, Lands and Heritage. The R-Code on the lot sets the limits the design has to sit within.
- The estate’s design guidelines. Many estates add their own rules on facades, garages and fencing. Ask for them before you choose a facade, not after.
- Corners and easements. A corner lot, a sewer easement or a truncation at the front can take usable width away even when the frontage measures 12.5m.
If you send us the lot details, we will check which designs genuinely fit before you commit to either the land or the home. Narrower than 12.5m? Our narrow lot home designs page sorts everything drawn for 6m to 10.5m.
Packages on 12.5m lots
Every package we list shows its lot size and frontage. The house and land packages page has the current list, and our suburb guides cover what to check in each growth area. Listings change quickly, so if you see one you like, ask us whether it is still available and which of these designs suit it.
We do not charge you for this. How we are paid explains why, and you can talk to us about a lot you are looking at any time.
Common questions
Is 12.5m a standard lot width in Perth?
It is the most common frontage on our books. As at 20 October 2026, 11 of the 30 packages we list that record a frontage sit on a 12.5m lot, and it is also the width with the most designs in our catalogue, at 19 of 46.
Can I put a 12.5m design on a 12m lot?
Do not assume so. Each design is drawn for a particular frontage, and the setbacks on the actual lot decide whether it fits. Send us the lot details and we will check it, along with the designs drawn for narrower lots.
How many four-bedroom designs fit a 12.5m frontage?
Fourteen. Ten of them have a dedicated home theatre, and four have a scullery.
Are any of the 12.5m designs double-storey?
No. All nineteen are single-storey. Our builder panel specialises in single-storey homes, and select double-storey options are available on request.
What is the smallest home drawn for a 12.5m lot?
Of the designs that publish a floor area, The Stillwater is the smallest at 149m², a three-bedroom home with its living areas at the rear.
