Kingswood's Local Home Building Specialists

Keystone Building is Penrith-based, so we know Kingswood's older housing stock well — the soil conditions common to the area and how Penrith City Council assesses a renovation application. That local knowledge is what keeps a Kingswood project on track from concept through to completion.

Our Services in Kingswood

More room for a growing Kingswood family, without leaving the home they love. Keystone Building are Penrith locals who've been designing and building second storey additions, ground floor additions and major home renovations since 1997, seeing every project through from first sketch to final handover.

Second storey additions

Build up with a second storey addition and keep your yard. Architecturally known as a first floor addition, Kingswood homeowners choose a second storey extension to add a whole new level of bedrooms, bathrooms and living areas above theirexisting home, without touching the backyard, pool or garden. The build usually starts with a structural engineer confirming your existing foundations can carry a new level, then moves on to removing the existing roof and reinforcing the structure below. For a growing family, it is one of the most popular home additions for gaining room without moving.

Ground Floor Extensions

Extend your home at ground level. Ground floor extensions Kingswood families love to add for single-level living include easy indoor-outdoor flow and step-free access. These ground floor extensions create more space and new living areas for everyday life without adding a staircase, and they can lift the value of your property at the same time.

Building in Kingswood: What Local Homes Need

Larger, established blocks

Many Kingswood homes sit on generous lots of 600 square metres or more. That land is the reason people move here, so wherever it makes sense we build up rather than out, adding living space while leaving the yard, pool and side access exactly as they are.

Reactive clay soils

Pockets across Western Sydney sit on reactive clay that swells and shrinks with the seasons. It is a normal local condition, not a barrier, but it does mean footings and any structural reinforcement are engineered specifically for your site rather than assumed.

Hot summers and BASIX

Keystone holds a 5.0-star rating across more than 40 Google reviews, with feedback from homeowners right across the Penrith LGA who have added a level, extended out or renovated with us.

Home addition & extension approvals

Every home addition or extension requires the right approvals. Depending on your project, this may be through a Complying Development Certificate (CDC) or a Development Application (DA) with Penrith City Council.

We identify the right approval pathway from the start and prepare your plans to meet the relevant planning controls, helping keep the approval process efficient and your project moving forward.

Why Kingswood Families Choose Keystone

Adding a top level, extending out or renovating is a big commitment, so the builder you choose matters. As a family-run business, Keystone makes the whole renovation process feel manageable, guiding you through every stage with quality workmanship and a genuine focus on your family's lifestyle. Here is why Kingswood families choose us.
