Granny Flat Draftsman Sydney | Design & Approval Plans
Local Knowledge. Plans That Pass. Space That Earns.
A granny flat draftsman works out what your back yard will legally hold before you spend a cent on a build, then draws the flat that fits it. That is where we start.
Most blocks in Sydney have room for a second dwelling. What decides the job is the 60 square metre limit, the setbacks, the trees you have to keep and where the sewer runs.
Kingsley Design & Drafting draws secondary dwellings across the whole city, from a studio behind a Ryde weatherboard to a two bedroom flat off a wide Blacktown block.
You end up with a drawing set a builder can price and an approval pathway chosen for your property rather than guessed at.
Granny Flat Drafting Service Sydney Wide
Two things decide whether a granny flat gets up. The block has to be 450 square metres or more with 12 metres of frontage, and the flat itself has to stay inside 60 square metres of floor area. Everything after that is arrangement.
Our granny flat drafting service Sydney owners use starts with the site, because the position of the flat sets the driveway, the private open space, the drainage and how much of the yard the main house keeps.

Why Use Kingsley Design & Drafting For Your Granny Flat?
A second dwelling is usually built to earn money or to house family, so every square metre has to do a job. Here is what a granny flat drafter puts into the set before it goes anywhere near a certifier.
The Block Gets Assessed First
Area, frontage, easements, trees and the fall of the land are checked before a single wall is drawn.
Sixty Square Metres Used Properly
Storage, laundry and circulation get planned early so the living space is not what gets squeezed.
The Main House Keeps Its Yard
Siting, windows and fencing are arranged so both dwellings have privacy and usable outdoor space.

Sydney granny flat builders can price the set as drawn, which keeps their numbers comparable.
Our Granny Flat Drafting Service Across Sydney
Second dwellings take a lot of forms, from a one room studio for a student to a full two bedroom rental, and this is the work a granny flat draftsman covers here:
- Studio, one bedroom and two bedroom granny flat plans
- Detached secondary dwellings on standard suburban blocks
- Attached flats and ground floor conversions under one roof
- Garage and outbuilding conversions into legal dwellings
- Sloping site designs with stepped floors and retaining
- Driveway, parking and private open space arrangements
- BASIX certificates and stormwater documents where needed
- CDC, DA and construction certificate drawing packages
What Makes Our Granny Flat Designers Different?
The 60 square metre limit is what makes this work interesting. A flat drawn without thought puts a hallway down the middle and loses 6 metres of it to walking. Move the entry, borrow the laundry off the bathroom wall, put the kitchen against the wet wall, and the same footprint gains a proper bedroom.
Rules also change what counts inside that area. A covered patio, an attic space or an unenclosed carport can sit outside the floor area calculation when they are designed correctly, which is worth knowing before you shrink the lounge.
A granny flat designer who knows the State Environmental Planning Policy for affordable rental housing will find you space that a generic plan set never had. That is most of the value in the drawings.
Our Promise: We walk the block, we draw it to the rules, we explain every step, and we stay with it until it is approved.

How Our Granny Flat Drafting Works
1. Talk It Through
Send the address and tell us who the flat is for, and we will say quickly whether the block meets the size and frontage rules.
2. Site Measure
We visit, measure the yard, locate services and trees, then quote the full drafting scope as one fixed figure with no add ons later.
3. Draft & Review
Layout options come first and get reworked until the plan suits you, then the full drawing set and any BASIX work is prepared.
4. Approval & Handover
We lodge with the certifier or council, respond to anything they raise, and hand you the stamped plans your builder works from.
Granny Flat Draftsman Sydney FAQs
Can I build a granny flat on my property?
In most of Sydney the test is straightforward. The lot needs to be at least 450 square metres, have 12 metres of frontage, be zoned residential and already have a house on it. Beyond that, easements, registered trees, flood or bushfire mapping and heritage listings can change the answer. We check the title, the planning certificate and the mapping for your address before you commit to anything, and tell you plainly if the block will not work.
How big can a granny flat be in New South Wales?
The internal floor area limit is 60 square metres for a secondary dwelling approved as complying development. What many owners miss is that some elements sit outside that figure when they are drawn correctly, including an unenclosed carport, a covered patio within the allowance and certain attic space. A granny flat drafter who plans for this at concept stage can give you noticeably more usable room inside the same legal footprint.
Do I need a development application or a CDC?
It depends on the block. A compliant flat on a regular lot in Hornsby, Liverpool or Canterbury usually goes through as complying development, which a private certifier can approve in a few weeks. Blocks with heritage listings, flood affectation, bushfire mapping or unusual shapes go to council as a development application instead. We check which pathway your property falls into before drafting starts, then prepare the set for that pathway.
What does a granny flat drafting service cost?
Price follows scope. A flat one bedroom flat on a level block with services close by needs far less documentation than a two bedroom dwelling on a slope requiring retaining, stormwater design and a bushfire report. Once we have the address and know what you want built, you get a written fixed price covering the site visit, concept work, the full drawing set and lodgement. Council and certifier fees sit outside that.
How long does the whole process take?
Drafting normally takes 3 to 5 weeks from the site visit, and the number of layout changes you want is what moves that. Approval runs separately. A complying development certificate often comes back within 3 weeks of lodgement, while a development application through a Sydney council commonly takes 8 to 12 weeks. We give you a program at the start and tell you where the job sits as it moves along.
Will you handle BASIX and the other reports?
Yes. Every new dwelling in New South Wales needs a BASIX certificate covering water, thermal comfort and energy, and we prepare it as part of the package so the glazing, insulation and fittings on the drawings match what the certificate commits to. Waste management plans, stormwater concepts and site plans for the certifier are prepared with the same set. Where an engineer or a bushfire consultant is needed, we coordinate them.
Can I rent the granny flat out?
Yes, a secondary dwelling approved this way can be rented to anyone, which is why so many owners in Campbelltown and Camden build them. The flat cannot be subdivided off the main lot or sold separately, and it stays on the one title with the house. Talk to your accountant about how the rental income and any capital gains position affects you, because that side of it changes what makes sense financially.
Do you work with my builder?
Yes, and it helps if they are involved early. Sydney granny flat builders quote faster and more accurately from a set that already shows the slab, the frame, the services and the finishes, so we send drawings across for comment before the set is finalised. If you have not chosen anyone yet, the documentation is prepared so three builders can price the same job and you can compare what comes back.
