Second Storey Additions Penrith – Expand Your Home Without Moving
Who We Are
Our family-run business is based in Kellyville, and we understand the needs of growing families in Penrith. From planning and approvals to construction and handover, we manage the entire process with transparent pricing and fixed build timelines.
Preserve Outdoor Space
Build vertically to maintain your backyard, garden, or pool area— ideal for smaller blocks.
Add Views and Light
Second levels can open up elevated outlooks and bring in more sunlight, enhancing both value and lifestyle.
Get More Privacy
Create spacious master suites or quiet study areas completely separated from the main living zone.
Boost Property Value
Second storey additions are a strong investment, often delivering a higher return by substantially increasing usable floor area.

Unlock More Space Without Sacrificing Your Yard
For families in Penrith, second storey additions are the perfect way to expand your home without giving up valuable outdoor space. Instead of extending outwards and losing your garden or entertainment area, building upwards gives you the extra bedrooms, bathrooms, or living areas you need while keeping your yard intact. This makes it the ideal solution for growing families who want both space inside and outside their home.
Keystone Building specialises in creating tailored second storey additions that seamlessly integrate with your existing home. We don’t just build; we design with your lifestyle in mind, ensuring the new space feels natural, practical, and adds real comfort to your daily life. Whether you’re looking for a luxurious master suite or extra space for the kids, we make it happen.
Add Value and Style to Your Home
A well-designed second storey addition doesn’t just give you extra space — it also enhances the overall look and feel of your property. In Penrith, where street appeal and property value matter, adding a second storey can dramatically increase both. With modern finishes, clever layouts, and a design that suits your existing home, you’ll enjoy the benefits of a stylish upgrade while investing in your future.
