Extensions and additions.

Additions, second storeys and whole home renovations, staged so the house stays weather tight and liveable throughout.

Adding to a house you are still living in.

Most of the homes we extend are heritage affected, occupied, or both. That changes the sequence of the build more than it changes the build itself.

Piper Moss brings together almost four decades of award winning building, with estimating and risk-control expertise gained through major NSW infrastructure projects.

What we add.

Extensions on established Sydney homes, planned around the way you actually use the place.

Rear additions

Ground floor additions that open the back of the house to the garden and the light.

Second storeys

Adding a level to an existing home, including the structural work underneath it.

Attic conversions

Using the roof space you already have, with proper access and headroom.

Whole home renovation

Reworking the whole plan rather than adding to a layout that never worked.

Kitchens and bathrooms

Wet areas with the waterproofing detailed properly the first time.

Heritage fabric

Conservation areas and heritage items, worked through council with the right trades.

Staged so you can stay in it.

We plan the work so the house stays weather tight at every stage, and so the parts you need most, a kitchen, a bathroom, a way in and out, are not all offline at once.

On a second storey that means getting the new roof structure on and closed before the existing ceiling comes out. On a rear addition it means keeping the existing rear wall working as a weather line until the new envelope is sealed.

In conservation areas and on heritage items the constraints come earlier, at council and in the documentation, rather than turning up as surprises mid build.

Working with us.

Inspect and scope

We attend site, establish what is actually wrong and put the scope in writing before anyone talks about price.

Estimate and de-risk

Priced line by line with the assumptions stated. Provisional items are named and capped, never buried in the total.

Build and hand over

Supervised on site, reported weekly, and handed over with documentation, warranties and a defects period we answer.
