Building Designer and Draftsman North Shore

A building designer works out what suits your block, then documents it well enough to be approved and built. That runs from the concept layout through the site plan, floor plans, elevations, sections and the technical notes your builder relies on. On the North Shore it also means testing the idea against heritage conservation provisions, tree protection zones and the fall across the site before the design is locked in. The council side sits with us, so one set of drawings carries both the development application and the construction certificate.

A draftsman gives you practical, council ready drawings at a lower cost, which fits most small and medium residential projects. Our weeks go on second storey additions, granny flats, decks, pools and retaining walls between Kirribilli and Hornsby, so we know what each of the seven councils here wants to see and what earns a request for more information. A bespoke architectural house is worth an architect fee. A project that needs approval and a buildable plan set is faster and cheaper through us.

A Development Application asks council for permission to build on a property or change how it is used. New homes, second storey additions, granny flats, pools, retaining walls, decks and outdoor buildings usually need one. The lodgement carries site plans, elevations, shadow studies, notification plans, engineering input and a written case for the scheme, plus an arborist report where trees are involved. We assemble that package so it reads clearly to the officer assessing it and does not stall waiting on a document nobody sent.

It depends on the project, the council and how complete the lodgement is. Smaller works such as decks, carports, driveways and retaining walls generally run around 6 to 8 weeks. New homes, second storey additions and granny flats are closer to 10 to 16 weeks. Sites in a heritage conservation area, or with significant trees or a watercourse at the rear, attract extra referrals and take longer again. Most delay we see comes from thin documents, so we lodge a full set and answer council questions on your behalf.

A Construction Certificate confirms that the approved plans comply with the Building Code of Australia and the Australian Standards that apply. You need one issued before work starts on site. Everything technical sits at this stage, structure, fire separation, waterproofing and energy performance. On a second storey over old brickwork the structural documentation matters most here, since the certifier wants to see how the new floor and roof loads reach the ground. We keep your engineer and certifier moving in step.

Often, yes. A pool and a retaining wall, or a deck and a carport, can go in together when they form part of the same works on the same site. One lodgement usually costs less and takes less time than two, and it saves your neighbours being notified twice, which on close North Shore blocks is worth something. Before we draw anything we ask what else is planned over the next year or two, then document the lot as a single package wherever the controls allow it.

You get a site plan, floor plan, elevations, sections and the lodgement documents for either complying development or a development application. Before any of that is drawn, the design is tested against zoning, setbacks, height, site coverage and private open space. On the North Shore we also check the tree canopy on and next to the block early, because a protected root zone can move a granny flat 2 metres and change the whole layout. From concept to lodgement we run each step.

Our bathroom draftsman draws the room layout, fixture setout, waterproofing and tiling dimensions, plus any structural or services changes the new layout needs. In an interwar or Federation house that means checking joist spans, floor levels and where the existing stack runs before the fixtures move. Most bathroom work sits under complying development or needs no application at all, though we confirm that against your project rather than assuming.

A kitchen renovation that stays inside the existing floor plan usually needs no application. Take out a wall, change the structure or push the footprint out and it generally does. In older North Shore homes an internal wall is often carrying the roof, so we check that before anything is quoted as a simple removal. Our kitchen draftsman draws the floor plan, joinery elevations and services layout, so the cabinetmaker, plumber and electrician build from the same drawings.

A new home needs the full set, site plan, floor plans, elevations, sections and the DA or complying development documentation, drawn around your levels, orientation and the planning controls on the land. On a North Shore knockdown that also means retaining, stormwater and tree protection resolved on the drawings, and a street elevation that sits comfortably next to the houses either side. Our custom home designer coordinates the consultant reports alongside the drafting.

Almost always, yes. Councils assess pools on setbacks, excavation, drainage, and barrier and fencing compliance, and it is those details that hold applications up rather than the pool shell. On a block that falls to the rear, the pool usually brings retaining and drainage with it, so we draw all three together. Where a mature tree sits near the excavation an arborist report is normally needed as well, and we build that into the set before lodgement.
