These projects accommodate evolving family needs with additional bedrooms, offices, or recreational areas while enhancing market appeal. Core WA's 34-year expertise ensures structural integrity and seamless integration with existing homes.

Commercial fit-outs cater to diverse business needs including medical centres, childcare facilities, and corporate offices. Projects maintain operational continuity through weekend work schedules and phased construction. Licensing compliance and minimal disruption are prioritised throughout the process.

Questions
Do I need planning permission for a second-storey extension?
Regulations vary by location and project size. Some areas require planning permission, while others allow certain extensions under permitted development rights.
Can I live in my home during construction?
Many clients remain in their homes during renovations. Feasibility depends on the project's scope and its impact on habitable spaces.
Are quotes fixed-price or estimates?
Quotes become fixed-price contracts once plans, engineering, and specifications are finalised. Preliminary figures without these documents are considered budget estimates.
Do renovations require building licenses?
Most structural changes require building licenses. We ensure all necessary approvals are obtained to prevent future issues with financing or property sales.
Is a custom home more expensive than a project home?
Custom homes can be cost-competitive when comparing complete inclusions. Our transparent pricing often results in higher quality finishes at similar price points to project homes.

Report
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

Report
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.

We engaged Core Developments to build and oversee our second storey addition & renovations. From the start Darren organised everything and the build went like clockwork.
Darren's tradesmen were very professional, reliable honest and very tidy, which was perfect seeing that we were living in the house while the build was happening. I would not hesitate to recommend Core Developments for 100% customer Satisfaction.
