Chatswood Building Designer & Draftsman | Homes and Extensions

Do I need council approval for a new home in Chatswood?
Yes. A new home is a development application in almost every case, assessed against Willoughby City Council’s controls for height, floor space ratio, setbacks and landscaped area. Sloping blocks and tree canopy, common through Chatswood, often bring extra requirements into a custom home design, which is why we check the site and the controls before any drawings start on your project.

What’s involved in extending an older Chatswood home?
Most extensions need approval, particularly a second storey addition or anything that changes the footprint. Our home extension drafting for Chatswood starts with measuring the existing house properly, since the new work has to tie into the roof, floor levels and structure that are already there before we draw a single new wall or window.

Can I build a granny flat on my Chatswood property?
Almost always, and the question is which pathway applies rather than whether one does. A secondary dwelling on a regular Chatswood block that meets the size, setback and private open space rules can often go through as a complying development certificate. Once the site slopes steeply or a heritage or tree constraint applies, our granny flat drafting shifts to a full development application instead.

Do backyard studios need approval around here?
Small structures can sometimes be built as exempt development in New South Wales, but height, size, boundary distance and zoning all have to line up correctly first. Our outdoor building drafting service checks your Chatswood block against the current rules before we draw anything, so you know which approval path applies before any concept work begins.

What does a Chatswood pool application need to cover?
Councils assess pools on setbacks, excavation, drainage and pool barrier compliance, and sloping Chatswood yards add retaining and levels into the mix as well. Our pool drafting service resolves the shell, surrounds, fencing line and excavation on the drawings before lodgement, so these details don’t hold up the application once it reaches the assessing officer.

Why do so many Chatswood projects need a retaining wall?
A good part of Chatswood steps down towards the Lane Cove valley, which puts a retaining wall into most rear yard projects in the area. Our retaining wall drafting covers the height, materials, footings and drainage that an engineer can certify, and that councils expect to see for any wall over a certain height or close to a boundary line.

Does a deck or pergola need council approval in Chatswood?
It depends on the height, position and how visible the structure is to neighbouring properties. On close set Chatswood blocks, an elevated deck can raise privacy and overshadowing questions quickly, so our deck and pergola drafting resolves height, screening and boundary distances before lodgement, rather than leaving them for council to query later.

Can I build a garage on a narrow Chatswood block?
Often, especially where the front building line, street tree and driveway all interact on a tighter frontage. Our garage drafting service starts by checking what a Chatswood frontage actually allows, since that decides whether the job needs a full development application or can go through as complying development instead.

Do I need approval to add a new driveway or crossover?
Yes, when the work changes vehicle access, gradients or the kerb in any meaningful way. Council and road authority both have a say, with standards for gradient transitions, sight lines and drainage. Our driveway drafting for Chatswood properties sets these out clearly on the plans, so the application is assessed against the right standards the first time it’s lodged.

Is a carport exempt development in this area?
Sometimes, but covered parking forward of the house is tightly controlled, and the answer changes from street to street across Chatswood. Our carport drafting service checks what a specific frontage allows first, then documents an attached or freestanding carport that suits the house and whichever approval path applies to your block.

Does a kitchen renovation need council sign off?
Most kitchen renovations that stay within the existing floor plan don’t need a development application, but structural changes, wall removal or an extended footprint usually do. Our kitchen drafting service for Chatswood homes documents the walls coming out, new openings and services, so the builder and cabinetmaker work from one accurate set.

What does bathroom drafting cover for a Chatswood home?
In older Chatswood homes, most bathroom gains come from moving a wall or borrowing space from a hallway rather than extending the footprint. Our bathroom drafting service documents the new layout, fixture positions and waterproofing detail the trades need to price the job accurately and build it without guesswork.

Can you handle DA and CC lodgement with Willoughby Council?
Yes. Our DA and CC drafting service for Chatswood properties covers the full application from start to finish, then we deal with any requests for information that come back from council or your certifier. Where the job qualifies as complying development, we can go to a private certifier instead, which is normally the faster path.
