In short
A structural engineer in Battery Point, South Hobart and the Hobart CBD works mostly on old masonry and timber buildings. Works to a place on the Tasmanian Heritage Register need Heritage Council approval, and structural changes need drawings of the existing condition. Our crack and foundation reports start from $590 + GST, heritage work is fixed-quoted, and you get a quote within 1–2 business hours.

Do structural works to a Battery Point heritage home need approval?
Usually, yes. Works to a place on the Tasmanian Heritage Register need the Heritage Council's approval, and a building in a Hobart local heritage place or precinct usually needs a planning permit as well, although some maintenance is exempt. Battery Point and South Hobart were both covered by the City of Hobart's heritage studies, so it is worth checking before anyone opens up a wall.
Heritage Register works go one of two ways. Smaller works can get a minor works approval, which was called a Certificate of Exemption before 2025. Larger works need a permit through a council development application. Either way, the Heritage Council's guidance asks for drawings of the existing condition next to the proposed structural works, and ground disturbance such as new footings may need an archaeological statement.
This is where a structural engineer comes in early. Our heritage and older homes service provides:
- An existing-condition record: what is there, how it carries load and what has moved
- The cause of any cracking, before anyone proposes a fix
- Repair or alteration drawings that keep sound original fabric where the structure allows
- A Form 35 for the building surveyor, and stage inspections where the work needs them
Which approval does structural work in Battery Point need?
That depends on two separate systems: heritage rules decide whether the change is allowed, and the Building Act decides how the building work is approved. Most heritage projects deal with both.
| Situation | Approval route |
|---|---|
| Smaller works to a Tasmanian Heritage Register place | Heritage Council minor works approval |
| Larger works to a Heritage Register place | Permit through a council development application |
| Building in a local heritage place or precinct (Code C6) | Planning permit usually needed; some maintenance exempt |
| Major structural repairs or underpinning | Notifiable building work: building surveyor and Certificate of Likely Compliance |
| Underpinning or shoring a neighbour's building | Protection work: building surveyor |

Why do old sandstone and brick walls crack?
Old masonry walls usually crack because something under or around them has changed. Water is a common culprit: a downpipe emptying against a wall, a leaking drain or a blocked gutter can soften the ground under a shallow footing. Roof loads that have spread over time, decayed timber lintels and nearby excavation are other common causes.
The cause decides the repair. A crack from a leaking drain may only need the leak fixed and the crack repaired, while a wall pushed out by a spreading roof needs restraint, not new footings. Soft stone and old mortar also need repair materials that suit them, which a heritage approval will look at too. A crack and foundation report from $590 + GST measures and rates the cracks to AS 2870, explains the likely cause and sets out the options. Our guide to cracks in walls explains the widths engineers look at.
What do CBD and South Hobart projects need from an engineer?
Mostly designs for alterations and protection for the buildings next door. City buildings often share or abut walls, so a new opening, a basement or an excavation on one lot can affect the next.
- New openings and wall removal, with beams, posts and footings designed for the load, from $550 + GST
- Dilapidation reports before nearby demolition or excavation, from $650 + GST
- Commercial condition reports and change-of-use checks for older city buildings
Commercial work, including commercial building inspections, is fixed-quoted per project. If you are not sure what you need, describe the building and the plan and we'll suggest where to start.
