Questions

Do I need planning permission for a second-storey extension?

Regulations vary by location and project size. Some extensions may require planning permission while others fall under permitted development rights.

Can I live in my home during construction?

Yes, many clients remain in residence. We implement protective measures and schedule disruptive work to minimise inconvenience.

What's the difference between an estimate and fixed price?

Fixed prices require detailed plans and specifications. Estimates provide budgetary guidance before finalising project details.

Are building approvals included in your service?

Yes, we handle all necessary approvals and ensure compliance with local regulations throughout the construction process.

How do renovation costs compare to moving house?

We help clients evaluate whether renovating offers better value than relocation, considering emotional and financial investments.

What commercial projects do you handle?

We specialise in medical centres, childcare facilities, office spaces, and retail fit-outs with experience in heritage and institutional buildings.

Core completed a small renovation to our home; they were a pleasure to work with; we absolutely loved the end product and their service. Darren was incredibly patient with our questions and took the time to explain the design decisions - coming up with numerous ideas to enhance the finished look and functionality. We really valued and appreciated working with the owner/builder directly rather than with a bureaucratic machine. Whist, a small job compared to Cores incredible builds we always felt that our renovation was equally as important when it came to quality, service and completion times

Ongoing damage. Despite being asked to move company vehicles Core wilfully continue to do damage with their parking. When brought to Darren's attention the only response was a refusal to assist. For something so easy to fix no effort was made. I wouldn't trust them with my house if this is the typical behaviour of staff and management!

My wife Fiona & I recently completed a very extensive renovation of our house in Floreat. The scope entailed both demolition and new build. The demolition component consisted of two bedrooms, a laundry, dining, kitchen and alfresco area. The new build entailed the extension of an existing bedroom (including raising the height of the room by 4 courses), a new master bedroom with ensuite and walk in robe, a new kitchen, dining, living and laundry as well as the addition of a carport and the replacement of the whole roof. To complicate things we wanted to remain in the house (six of us) during construction

Darren and his team were wonderful. We had a second story addition completed in under 6 weeks when the weather was atrocious! From start to finish they were a pleasure to work with and the quality of the finished product was outstanding. We probably were not the best of customers and they were nothing but professional at all times.
