Frequently asked questions
What makes a 12.5m x 30m house design different?
With 30m of depth, you have the freedom to include more bedrooms, multiple living areas, larger kitchens, outdoor spaces and dedicated study zones. Our house plans for 12.5m x 30m blocks are tailored to maximise this added space.
Can I fit a pool or a large garden?
Yes. Many of our designs leave room at the rear of the home for alfresco areas, play zones, landscaped gardens or a small pool, depending on the layout you choose. If you're looking for impressive landscaping ideas that will transform your exterior, we can help
How much will my new home cost?
Our home designs for 12.5m x 30m blocks start from $268,900. Pricing will vary depending on the floorplan, upgrades and location. Use our building cost calculators or speak with our experts for an accurate estimate.
Can I change the layout or finishes?
Yes. We offer complete flexibility through our Spectra design process, giving you control over finishes, floorplans and inclusions.
Are there council or planning restrictions I should know about?
Yes. Local regulations and setbacks affect every site differently. Our team will assess your block and work with your council to ensure your design meets all necessary requirements.
How long does it take to build on a 12.5m x 30m block?
Your build will include three key phases: pre-site, construction, and warranty. In the pre-site stage, we help you finalise your floorplan, secure finance, sign contracts, and gain approvals.
During construction, your home is brought to life with regular updates via Carlisle Connect, our online client portal. After handover, the journey continues, giving you an easy way to manage your warranty period and schedule any necessary services. Our average build timeline varies depending on your block, design, and council conditions, but we always keep you informed and on track.
