3D LiDAR Scanning Homes Double Bay Sydney

Understand your home before planning changes

Planning a renovation, extension or internal redesign in Double Bay? Before preparing detailed drawings, it helps to establish how your home is built today.

Original plans may be missing or may no longer reflect previous alterations. Walls, openings, floor levels and ceiling heights can differ from what appears on an old drawing.

Hamilton By Design provides 3D LiDAR scanning for homes in Double Bay, Sydney NSW, capturing visible, accessible building surfaces to create a measured digital record. This information helps architects, building designers, engineers and builders develop proposed changes around existing conditions.

Whether you are opening up a living area, replacing a staircase or extending your home, scanning provides a practical starting point for design.

What is residential 3D LiDAR scanning?

A terrestrial LiDAR scanner measures building surfaces from a series of stationary positions. Individual scans are combined into a registered point cloud, representing the geometry captured throughout the property.

Unlike a collection of separate room measurements, a coordinated point cloud allows the project team to review adjoining spaces together. This helps explain how rooms, openings and levels relate to one another.

Depending on access and the agreed scope, residential scanning can capture:

Internal walls, floors and ceilings.
Door and window openings.
Stairs, landings and surrounding spaces.
Visible beams, columns and bulkheads.
External façades and accessible roof geometry.
Balconies, terraces and courtyards.
Visible services and equipment.
Areas where proposed construction will connect to the existing home.

The dataset can then support selected existing-condition drawings or 3D CAD modelling where these outputs are commissioned.

Why scan a Double Bay home before renovating?

A renovation often changes how several spaces work together. Removing a wall, enlarging an opening or changing a staircase can affect adjoining rooms, circulation and the position of new fixtures.

Understanding these relationships early gives the designer more useful information when assessing options.

Replace assumptions with measured geometry

A room that appears rectangular may have walls that are slightly out of square. A ceiling may change height around a bulkhead. An opening may be positioned differently from the original plans.

These details can affect cabinetry, glazing, stairs and other components that must fit the existing building.

Scanning helps document accessible geometry so the design team can identify where closer checks are needed.

Review adjoining rooms together

For a kitchen and living room renovation, individual room dimensions may not explain the whole layout.

A registered point cloud can show the relationship between the kitchen, hallway, living area and outdoor opening. This helps the designer assess proposed layouts within the wider space.

Keep a record before demolition

Once walls, ceilings or fittings are removed, their original positions may be difficult to reconstruct.

A pre-renovation scan preserves a measured record of the surfaces captured. The project team can return to that information when reviewing an original opening, room arrangement or connection detail.

Applications for home scanning in Double Bay

Kitchen and living area alterations

Changing the kitchen layout or creating an open living area requires an understanding of existing wall positions, openings, ceiling geometry and floor levels.

Scanning can provide the spatial reference for developing the proposed layout. Structural decisions about removing walls require assessment by the appropriate engineer.

For custom cabinetry, critical installation dimensions should be checked to the tolerances required by the supplier.

House extensions

An extension must connect with the home already on site.

Scanning the adjoining rooms and relevant external surfaces helps document the geometry around floor transitions, doorways, eaves and accessible roof junctions.

This information supports the design of the connection between existing and proposed construction.

Staircase replacements

A new staircase needs to work within the available opening and connect with actual floor levels.

Capturing the stairwell, adjoining landings, nearby doors and ceiling surfaces helps the project team review the available space. Stair design, structural adequacy and compliance remain part of the relevant professional assessment.

Glazing, doors and joinery

Large windows, sliding doors and fitted joinery can depend on the relationship between several existing surfaces.

Scan data can support coordination and modelling of those interfaces. Where components require a close fit, targeted dimensional verification should form part of the agreed workflow.

Balconies and terraces

A renovation may involve changes to a balcony, terrace or the opening between indoor and outdoor areas.

Scanning accessible surfaces can help document thresholds, edges, nearby walls and level changes. Waterproofing, drainage, structural design and other specialist requirements need separate assessment.

Building services alterations

Visible pipework, ductwork and equipment can be captured where accessible. This can help coordinate proposed changes around existing services.

LiDAR does not reveal pipes, wiring or framing concealed behind walls and ceilings.

A practical example: redesigning a kitchen and terrace connection

Imagine renovating a Double Bay home to create a larger kitchen and improve access to an outdoor terrace.

The proposal includes new cabinetry, a wider glazed opening and a revised internal layout. The designer needs to understand how the kitchen floor, ceiling, adjoining walls and terrace threshold relate to one another.

A targeted scan can capture these accessible areas together before the design is finalised.

The project team can then use the point cloud and any commissioned drawings to review the layout and identify interfaces needing further investigation. Before ordering glazing or cabinetry, the relevant supplier can verify the critical dimensions.

This approach helps bring measurement questions into the design stage, when adjustments are easier to make.

From a home scan to useful project information

The right deliverable depends on who will use the data and what they need to do with it.

Some designers can work directly with point clouds. Others require selected drawings or a model of the building areas being changed.

Hamilton By Design can scope the following outputs around your project.

Registered point cloud

A coordinated dataset representing the captured surfaces, supplied in an agreed format compatible with the project team’s software.

Existing-condition drawings

Selected floor plans, elevations or sections prepared from the scan data where included in the quotation.

3D CAD models

Models of agreed building geometry to support layout review, communication and coordination.

Selected interface documentation

Drawings or modelled geometry focused on particular openings, stairs or connections relevant to the proposed work.

Scanning, drawing preparation and modelling are defined in the agreed scope. This makes clear which areas will be captured and what information will be supplied.

How we plan residential scanning

1. Understand the proposed changes

Share your property location, available plans and a description of the work. Your architect or designer’s requirements help determine the capture areas and outputs.

2. Identify important interfaces

We discuss the dimensions and connections that matter most to the project, including any fabrication requirements or restricted areas.

3. Arrange access

Clear sight lines improve capture. Furniture, stored items and vegetation may obscure surfaces, so preparation is considered before the visit.

4. Capture the agreed areas

The scanner is positioned at multiple locations to collect overlapping views of accessible building surfaces.

5. Process and prepare the deliverables

The scans are registered and reviewed before the agreed point cloud, drawings or models are prepared. Relevant coverage limitations are communicated to the project team.

When should you scan your home?

For most renovation and extension projects, scanning is useful before detailed design is finalised and before demolition starts.

Capturing early allows the existing geometry to inform the proposal.

Further scanning may be appropriate after demolition exposes additional surfaces, before installing selected components or at completion. Each visit should have a defined purpose and an agreed scope.

Frequently asked questions

Can you scan an occupied home in Double Bay?

Yes, subject to suitable access arrangements. Furniture and personal items may obstruct surfaces, so we discuss the areas that need clear views before scanning.

Can I arrange scanning if I have no existing plans?

Yes. Scanning can provide measured information from which selected existing-condition drawings can be prepared. Those drawings need to be included in the agreed scope.

Do I need to scan the entire property?

Not necessarily. A focused renovation may only require the affected rooms and adjoining interfaces. A substantial extension or redesign may benefit from broader coverage.

How accurate is 3D LiDAR scanning?

Accuracy depends on the equipment, site conditions, scan positions, registration and the feature being measured.

The intended use and required tolerances should be discussed before capture. Critical fabrication dimensions may require additional verification.

Can the scanner see through walls?

No. LiDAR captures surfaces visible to the scanner. Concealed framing, wiring, pipes and other hidden features require access or a separate investigation method.

Will I automatically receive floor plans?

Floor plans, elevations, sections and models are additional outputs that must be included in the agreed scope. A point cloud is the underlying measured dataset.

Can my architect use the scan?

Yes, provided the deliverables suit their software and workflow. We confirm the required formats and outputs before work begins.

Does scanning confirm whether a wall can be removed?

No. Scanning can document visible wall positions and surrounding geometry. Determining whether a wall is load-bearing requires assessment by an appropriately qualified professional.

Does residential scanning replace a boundary survey?

No. Capturing building geometry does not establish legal property boundaries. Boundary and cadastral survey requirements should be addressed by an appropriately qualified surveyor.

How much does scanning a home in Double Bay cost?

The price depends on property size, capture areas, access, processing and the required drawings or models. Available plans, photographs and a project brief help establish an appropriate quotation.
