Home Extension FAQs
Here are some common home extension questions we regularly get asked.
Both are accredited and regulated in Australia, with an architect providing more complex plans. A building designer normally provides an architectural design at a considerably lower rate than an individual architect making it more cost effective. Trust us for a Building Designer Melbourne.
Using the approach of “design and construct” gives you budget certainty, as you work with a suitable budget at the start of the design process and receive a detailed building cost estimate before the works are carried out. You also have a single project manager making things run smoothly and giving you a central point of contact.
When choosing a building designer, look for someone who understands your vision and has a strong portfolio of completed work. A good designer will be registered with the Victorian Building Authority (VBA), have experience with local council requirements, and offer clear communication throughout the process.

The timeline for a kitchen renovation depends on the scope of work, but on average, it takes between 4 to 8 weeks to complete. A minor update, such as painting, replacing cabinetry doors, or upgrading appliances, may take as little as 2-3 weeks. However, a full kitchen renovation that involves layout changes, custom cabinetry, new plumbing, and electrical work can take longer.
The process typically follows these stages:
Planning and Design (2-4 weeks): This includes selecting materials, finalizing layouts, and obtaining necessary approvals.
Demolition and Preparation (1-2 weeks): The old kitchen is removed, and the space is prepped for new installations.
Plumbing and Electrical Work (1-2 weeks): Necessary wiring and pipework are installed before cabinetry and benchtops.
Cabinetry, Benchtops, and Flooring (2-3 weeks): This includes fitting new cabinets, installing benchtops, and laying flooring.
Final Touches (1-2 weeks): Painting, backsplash installation, and appliance setup complete the process.
Delays due to material shortages, custom orders, or unexpected structural issues can extend the timeline, so working with experienced professionals can help ensure a smooth renovation.
Every kitchen is different but on average, we see Gold Coast kitchen renovations taking between 6 and 9 weeks. For larger projects it is on the longer end – for small kitchen renovations it sometimes only takes a month. Contact us on 1300 020 232 to find out more about the process.
To estimate the cost of a kitchen renovation, consider the following factors:
Basic kitchen renovations (new benchtops, cabinet refacing, appliance upgrades) start at $15,000 – $25,000.
Mid-range renovations (custom cabinetry, stone benchtops, layout adjustments) range from $25,000 – $40,000.
Luxury renovations (bespoke designs, premium appliances, high-end finishes) can exceed $50,000.
To get an accurate estimate, outline your renovation goals, compare quotes from multiple contractors, and factor in costs for permits, labor, and materials. Consulting a professional ensures a realistic budget and a smooth renovation process.
A well-designed extension can significantly increase the value of your home, provided it meets market demands and is built to a high standard. Adding extra bedrooms, additional living space, or a modern open-plan kitchen can make your home more functional and appealing to potential buyers. In particular, adding a second storey or expanding the kitchen and living areas can offer a great return on investment.
However, the amount of value an extension adds depends on factors such as location, quality of workmanship, and how well the extension integrates with the existing structure. If an extension is poorly designed, doesn’t match the rest of the house, or overcapitalizes on the area (i.e., costs more than the increase in property value), it may not yield the financial returns expected. To maximize value, work with an experienced builder and ensure the extension is practical, energy-efficient, and aligns with current market trends.
We spend a great deal of time each day in our bathroom. So ensuring it is both functional and relaxing is crucial. It is also one of the most important rooms prospective buyers evaluate, so having a modern bathroom makeover will increase your resale value.
Yes, redoing a bathroom is generally a great investment, as it can significantly enhance both the functionality and value of your home. A modern, stylish bathroom is a key selling point for buyers and renters alike. Upgrading outdated tiles, fixtures, and fittings, improving lighting, and ensuring high-quality waterproofing can make a space feel more luxurious and efficient.
According to property experts, a well-executed bathroom renovation can yield a return on investment (ROI) of up to 60-80%. The key to maximizing value is to balance cost and quality—overcapitalizing on high-end features that don’t align with the home’s overall market value can reduce profitability. Simple upgrades, like improving ventilation, adding storage, and installing energy-efficient fixtures, can make a big impact without blowing your budget. Whether you’re renovating to sell or to improve your living space, a refreshed bathroom can add significant long-term value.

Yvonne Lyons2024-09-21Our very old house consists of a 1980s extension attached to an old 1930s weatherboard. The older end was made up of small rooms, floors that ran downhill and leaky spots in the roof. It was cold, dark and drafty. CDC provided detailed drawings, engineering and planning permits, then came in and gutted it, opened it up and rebuilt it and leaving us with a warm, dry, light filled living area, new study and fully equipped kitchen with walk in pantry. They were sympathetic to the old farmhouse style while providing quality workmanship throughout. Matt’s team of skilled tradies, we’re brilliant to work with, committed to great results and regular communication. We would recommend CDC to anyone looking for reliable quality builders.Nigel Neaves2024-09-19In a word, CDC are 'Exceptional'. Their pricing was more competitive than other quotes I sought and their Scope of Works was very comprehensive and professionally presented, going beyond my specific requirements. Their team workmanship, punctual attendance and tidiness and the timeline of the work not only exceeded my expectations but also exceeded building industry standards and engineering which was supported throughout the works in progress by photographic evidence. I'm genuinely impressed with CDC and already booked them to return and replace the decking around our pool and install a ceiling above outdoor recreational area. Highly recommended, CDC deserve 6 stars not 5! You would be remiss not to contact them for a quote. Believe me! NNKerry Ashford (dj kashford)2024-09-16We are absolutely amazed with our experience with Matt & Mark and the whole team from Concept Design Construct on our house repair project. Our house unfortunately just a day before Easter 2023 had a car drive into the front section, the assessment of the damage was severe, made worse dealing with the insurance company’s appointed builder dragged on and process was painful to the point it drove our stress points thru the roof for months on end, until we searched for a local & highly rated builder, so we pulled the trigger to engage with CDC. Mark & Matt was empathetic, down to earth to our issues, keen to tackle our rebuild. Everything was seamless and of highest quality to the spec of the original home or executed with consultation to our needs. The rebuild by CDC took a lot less compared to having to wait another year as quoted by our insurer builder, and we love being back in our home. If you wanted a company that will stand by you, while working through insurance repairs, or all builds - Concept Design Construct is highly recommended.Vickie Berzins2024-09-12Mark and team were extremely helpful, prompt and nothing was too much trouble. The job was completed in a timely manner and he went above and beyond what was expected. The team dynamic was impressive and you could see there was a good work culture amongst the boys.

Their professionalism is second to none. Mark and Flo worked with me to find solutions to problems that come with renovating a 50-year-old building and offered helpful suggestions with the design and finishing touches, and regularly consulted with me to ensure I was kept up to date with the progress. Nothing was too hard for them, and they strived to make sure everything I wanted could be achieved. I highly recommend Concept Design Construct for your next project.Michael Egan2024-04-09It took us 12 months and numerous attempts to find a builder who would respond to our enquires.

The teams design and concept drawings and ideas to re-model our house were fantastic. We appreciated the honesty of the team and they provided us with confidence to proceed.
