Second Storey Addition Packages · Ashfield
Add bedrooms, bathrooms & living space, without moving.
Fixed-price second storey additions for Ashfield homeowners, from $269,000. Built to our Above Standard Carpentry Specification, with a solid Hebel PowerFloor included as standard on early projects.
Hebel PowerFloor included free on early Ashfield packages booked June to December 2026. A solid, quieter floor, normally an upgrade.
Space without moving
More room, without leaving the Inner West.
You love your Ashfield street, your neighbours, the school run. What you don’t love is running out of space. Moving means stamp duty, agent fees and starting over somewhere that may never feel like home.
A second storey addition (or second storey extension) lets you stay exactly where you are and build the space you need: extra bedrooms, a second bathroom, a private master retreat or an upstairs living zone, without giving up a metre of backyard. You build up, not out.

The Strava difference
A solid, quieter upstairs.
Most second storey additions sit on 19mm lightweight particleboard. While it does the job, it can feel hollow and bouncy underfoot. As a result, footsteps carry straight down to the rooms below.
For early Strava Group projects in Ashfield we include Hebel PowerFloor as standard. It’s a 75mm autoclaved aerated concrete (AAC) panel, almost four times thicker than standard flooring. Laid over your joists, it creates a solid, concrete-style floor.
- 75mmAlmost 4× thicker than standard 19mm particleboard, so it feels solid underfoot with no bounce or flex.
- 0Squeak-free. The thick AAC panel doesn’t creak the way timber-based flooring can over time.
- ↓Helps reduce noise transfer between levels for a quieter upstairs, especially with the right ceiling system.
- ✦Non-combustible AAC, with thermal insulation and moisture resistance built in.
