Home Extension Draftsman Sydney | Addition Plans

Local Knowledge. Plans That Pass. Space That Works.

Looking for a home extension draftsman who can tell you what will fit on your block before you fall in love with a layout? We measure the house, draw the addition and take it through approval.

Extensions are the hardest drafting job there is, because the new part has to meet an existing house that was never built square, level or to any drawing.

Kingsley Design & Drafting works on additions right across Sydney, from a rear pop-out on a Marrickville terrace to a second storey over a brick veneer in Baulkham Hills.

You get a full set of home additions drafting plans your builder can price, and the approval pathway sorted before anyone lifts a hammer.

Home Extension Drafting Service Across Sydney

Every addition begins with the house you already have. Wall thicknesses, floor levels, roof pitch, where the sewer main runs and which walls are actually holding the roof up all decide what the new space can be, and none of it is on a plan anywhere.

So we start by measuring what is there. From that, a home extension drafting service can draw an addition that lands on the existing structure properly instead of one that looks good until the builder opens a wall.

Why Use Kingsley Design & Drafting For Your Extension?

Adding to a house costs more per square metre than building new, so the drawings have to be worth what they save you. Here is what a home extension drafter Sydney owners keep coming back to actually does.

The Existing House Gets Measured

Levels, wall lines and roof framing are recorded on site first, so the addition is drawn to the house as built.

l

Old And New Meet Cleanly

Roof tie-ins, floor level changes and matching brickwork are resolved on paper, not argued about on site.

You Can Still Live There

Where it is possible we stage the work so the kitchen and a bathroom stay usable through most of the build.

Priced Before It Is Approved

The set is detailed enough for real builder quotes, so the budget conversation happens before council does.

What Makes Our Home Extension Designers Different?

We have drawn enough additions onto Sydney housing stock to know what each era hides. A federation cottage has no footings worth the name under the side wall. A 1960s brick veneer has a roof that cannot take a floor above it without a new frame. A 1990s project home has trusses that stop the wall you wanted to remove from going anywhere.

None of that shows up on a real estate floor plan, which is why an extension drawn from one gets expensive halfway through. We find it at the measure stage while it still costs an hour instead of a variation.

A home extension designer earns their keep in the space between what you want and what the house will actually give you, and most of the time there is more of it there than owners expect.

Our Promise: We show up, we measure it properly, we draft it right, and we help you get it approved.

How Our Home Extension Drafting Works

1. Talk It Through

Tell us the address, what you want more of and roughly what you want to spend, and we will say early whether the block and the house can carry it.

2. Site Measure

We come out and measure the existing dwelling, check zoning, setbacks and overlays, then quote the full drafting scope as one fixed figure.

3. Draft & Review

Concept layouts come first and get changed as often as you need, then the working set is drawn once the plan is one you are happy to build.

4. Approval & Handover

We lodge the application, answer whatever council or the certifier asks, and hand over the stamped plans your builder starts from.

Home Extension Draftsman Sydney FAQs

What does a home extension draftsman do that a builder does not?

A builder prices and constructs what is on the drawings. Our job is producing those drawings, which means measuring the existing house, working out what the block and the planning controls allow, resolving how the new structure ties into the old one, and preparing the documentation council or a certifier needs to approve it. Doing that first is what lets three builders quote the same job on the same information, so the prices you get back are actually comparable.

Can you add a second storey to my house?

Often yes, though it depends on what is underneath. The existing footings, the wall framing and the roof structure all have to carry the new load, and on many Sydney homes some of that needs upgrading. We measure the house, get an engineer to look at anything doubtful, and tell you honestly whether a second storey stacks up or whether a ground floor addition gives you the same space for less. Height limits and overshadowing rules matter here too.

How much do home additions drafting plans cost?

Scope sets the price. A single room bump out with no structural change needs a fraction of the documentation a full second storey does, and a heritage conservation area or a bushfire overlay adds reports that a plain suburban block never needs. After we have the address and your brief you get a written fixed price covering the site measure, the concept work, the full drawing set and the lodgement. Council fees sit outside that and we tell you what they will be.

Do I need council approval for an extension?

Almost always something is required. Many single storey additions on regular blocks in suburbs like Penrith or Sutherland qualify as complying development, which a private certifier can approve in weeks rather than months. Anything over the size, height or site coverage limits, or on a block with an overlay, goes to council as a development application. We check your property against the rules before drafting and tell you which pathway you are on.

How long does the whole process take?

The drafting itself usually runs three to six weeks from the site measure, depending on how many concept revisions you want, and that part is worth taking time over. Approval is the variable. A complying development certificate can come back in a couple of weeks, while a development application through a Sydney council commonly takes eight to twelve weeks and longer if a neighbour objects. We give you a realistic program at the start.

Can we live in the house while the extension is built?

Frequently yes, and it is worth planning for at the drawing stage rather than hoping. Where the addition sits away from the existing kitchen and bathroom, the build can be staged so those rooms stay in use until the new structure is closed in. Where the work goes straight through the middle of the house it is harder, and we will say so. Homeowners in Chatswood and Bankstown have run entire builds this way.

Will the addition match the existing house?

That is a decision you make and we draw either way. Some owners want the extension to disappear into the original, which means matching brick, roof pitch and window proportions as closely as the current market allows. Others want a clear break, with a lighter modern form behind an untouched street frontage, which councils in heritage areas often prefer. Either approach works, and we will show you both on the concept drawings.

Do you work with my builder and engineer?

Yes, and the earlier they are involved the better the result. A home extension drafter Sydney builders like working with produces sets that answer the questions they would otherwise ring about, so we send drawings to your builder for comment before finalising, and coordinate directly with the engineer on anything structural. If you have not chosen a builder yet, the documentation is prepared so any of them can quote it fairly.
