Contact usAdding upward means assessing the existing structure's capacity to carry additional load before anything else, sometimes requiring reinforced footings or new structural beams below. We manage this engineering assessment as the first stage of any Second Storey Addition Hobart project, before design work locks in.
Most second storey additions mean living under a partially exposed roof for at least part of the build, which takes more careful sequencing and weatherproofing than a ground-floor job. Our guide on live-in renovations in Hobart covers what that looks like in practice.
Where a single storey extension would eat into a small yard, going up instead keeps the ground floor and garden intact. Our guide on what home extensions add the most value in Tasmania touches on when adding upward pays off compared with extending out.
Adding a second storey means getting the engineering assessment right before a single wall goes up, and that's not something to leave to whoever's cheapest. Zak and Tom manage that assessment and the build personally from footings through to final handover, rather than passing the structural risk down to a subcontractor.
Can any house have a second storey added to it?
Not always. It depends on the existing footings and structure being able to carry the additional load, or being upgraded to do so. We assess this engineering question before anything else on the project.
Do I need to move out while a second storey is being added?
Often you can stay, though expect a stretch with the roof partially open and more noise and disruption than a ground-floor job. We plan the sequencing to minimise how long that stage runs.
How long does a second storey addition typically take?
Generally longer than a single storey extension of similar size, given the structural engineering and roof removal involved, though it still usually falls within the 8 to 20 week range for extensions depending on scope.
Is a second storey addition more expensive than extending outward?
Usually yes, because of the additional structural engineering and temporary roof protection required. Our guide on home extension costs in Hobart covers what drives cost differences between extension types.
Do I need council approval for a second storey addition?
Yes, given the scale of structural change involved. We manage the approvals process as part of the project.
