We add second storeys to existing homes across Sydney. Major structural work — foundation assessment, engineering, new framing, stairs, and roofing — fully managed from approval to handover.
When your block cannot go wider or deeper, the answer is up. A first floor addition doubles the liveable area of a single-storey home without reducing your outdoor space or yard.
This is serious structural work. Your existing foundations were built to carry a single-storey load. Adding an entire level above means we need to assess whether those foundations can handle the new weight — and if they cannot, we underpin or reinforce them before construction begins.
We work with structural engineers from day one. Every first floor addition we build has engineered footings, a properly designed load path from roof to ground, and full council approval before we pick up a tool.
Adding a storey is one of the most complex residential projects. Here is what we manage on every job.
First floor additions raise specific challenges that ground-level extensions do not. We address these upfront, not halfway through the build.
Most single-storey homes in Sydney were not built to carry a second level. We assess existing footings early and determine whether underpinning, additional piers, or foundation upgrades are needed before we commit to a design.
Some homeowners stay in the house during construction, others move out. We plan the staging to minimise disruption — roof removal and weather sealing is managed in controlled phases to keep the ground floor protected.
Second storey additions trigger height, setback, and overshadowing requirements. We coordinate with your architect or designer to ensure plans comply before lodgement, reducing the risk of delays or objections.
We inspect the existing home, review the plans, and commission geotechnical and structural assessments. This tells us what the foundations can handle.
Structural engineers design the new level. We manage DA or CDC submissions with all required documentation and respond to any council conditions.
If underpinning or reinforcement is required, we complete it before any vertical construction begins. This stage is non-negotiable.
Roof removal, new framing, roofing, cladding, windows, stairs, services, and internal fit-out. Every stage inspected and documented.
Final inspections, occupation certificate, and full project documentation. Your home is now two storeys — built properly.
Send us your existing plans or tell us what you need. We will assess the feasibility and give you a realistic view of cost, timing, and what your foundations will require.
