Ground Floor Addition
At Trinity Design and Construction, we bring your plans to life. Whether you have architectural drawings or a designerโs concept, we manage the entire build from start to finish. From site preparation to final handover, our team delivers your custom home with precision, quality, and care.
Second-Storey Additions
Adding another level to your home is ideal if you need more space but donโt want to sacrifice your yard. This is particularly popular in areas where land is limited. Itโs a great way to double your space while maintaining your outdoor area.
Rear Extension Additions
Extending the back of your house with a rear addition is a fantastic way to create additional space, often for open-plan living areas that connect better to your backyard. This type of addition is perfect if you want to maximize natural light and create a seamless indoor-outdoor flow.
Side Return Extension Addition
If you have a narrow strip of land along the side of your home, you can use it to expand the width of your house. This is a practical addition option for homes like terraces or semi-detached properties where space is tight, and itโs commonly used to enlarge kitchens or dining areas.
Granny Flats or Studio Additions
Adding a detached granny flat or studio in your backyard is a great way to create additional living space. This is especially useful if you desire to extend family living, or if youโre interested in earning rental income.
Outdoor Living Extension Additions
Expanding your outdoor space with features like covered alfresco dining areas, verandas, or pergolas is another popular choice. These extension additions create a perfect spot for entertaining, relaxing, or enjoying Sydneyโs weather. They also help blur the lines between indoor and outdoor living, making your home feel larger and more versatile.
Attic or Loft Conversion Additions
Converting your unused roof space into a functional attic or loft is a clever way to maximize your home’s potential without altering its footprint. These spaces can be transformed into cozy bedrooms, home offices, or even playrooms. This option is particularly popular in older Sydney homes with steep roof pitches.
Basement Conversion Additions
If your property includes a basement or subfloor space, converting it into a functional area is a fantastic way to add value and increase living space. Basements can be turned into media rooms, gyms, or self-contained apartments. Itโs especially valuable in areas where building outward isnโt an option due to limited land.
Glass Room Extension Additions
Adding a glass room or conservatory is an excellent way to create a bright and airy space that connects you to your garden. These are ideal for dining areas, sunrooms, or relaxation spaces where natural light is a priority. Theyโre perfect addition for homeowners who want a modern, stylish addition.
Home Office Extension Additions
With the rise of remote work, the addition of a dedicated home office is increasingly popular. This type of extension can be added to any part of your home or even as a standalone structure in your yard. Itโs a functional and value-adding solution for modern lifestyles.

Determining the final cost of your custom home build is a thoughtful process that balances scope, timeline, and quality. Itโs more than just a numberโitโs a carefully crafted estimate designed to align with your vision and practical needs.
As we define the projectโs scope, pace, and desired quality, we consider key factors like site conditions, structural requirements, materials, and compliance with regulations. Elements such as council approvals, permits, and building codes also influence the overall cost framework.
Only after navigating these variables can we present an accurate estimate. This is a collaborative stage where we adjust the scope, timeline, and features to ensure they align with your budget and aspirations.
Your financial comfort is always a priority. Through open communication, we ensure the cost reflects a perfect balance between your vision and practical considerations. Together, weโll refine the details, creating a plan that brings your dream custom home to life while staying within budget.
This isnโt just about extending your homeโitโs about creating a personalized experience. The final cost represents our shared commitment to delivering a high-quality home build tailored to your needs.

Weโve had a great experience working with Josh and the team at Trinity. They have impressive communications, process and quality in their work. We have a beautiful deck thanks to them, and are already moving on to the next project. I recommend them to anyone for a building project.
Excellent service, professional job & workmanship, always on time. Quoting process captured all our requirements & were remembered during the job as needed. The teamโs professional & respectful approach was much appreciated. They ensured that they cleaned up at the end of each day. They communicated fully all the way through the project. Highly recommend this company.
Joshua, Dylan and the team are wonderful builders. They fixed my driveway issues,, including replacing a retaining wall. Trinity created a beautiful deck with a privacy wall incorporating my rubbish bins. Internally, they fixed my window problems. Thanks guys !! I am very happy.
The best company I have ever dealt with. I canโt recommend these boys enough. 100/10 Always on time and their work is amazing. Thank you for everything you have done.
We had a custom designed wooden deck built and moulded to the shape of the pool. The results was amazing, Trinity Design and Construction were very professional and very plesant to work with.
Trinity Design & Construction built our backyard retaining wall and also our large decking area. They are highly professional, on time, polite, informative and their workmanship was outstanding. Highly recommend.
We found the team at Trinity Design & Construct to be really easy to work with. Their attention to detail was second to none and we wouldn't hesitate to recommend them.
Trinity Design & Construct came out to repair a leaking window that required a strip down of one side of the house, they were on time, courteous, and left the site clean and tidy, most importantly; the repair worked! Thanks to Josh and the team for all your hard work, we will definitely be using their services again.
We employed Trinity D&C to undertake many differing construction items in the build of our new home. Each task was undertaken with the quality, expertise, & efficiency that we were looking for. As I was also the Building Designer of the project, I was particularly impressed with the level of interest they took in the aesthetic detail that was required, & then the formulating of the construction methodology. Many a tradesperson would have simply looked for the simplest & most expedient way of completing the job. I have nothing but praise for Trinity D&C, & am forever grateful for their efforts. Thank you. Dan Briffa (Home Owner & Designer)
