Home Extension Builders Sydney | Home Renovations & Extensions
Your Peace Of Mind Is Our Goal
If you love your place, but things are feeling a bit cramped, home extensions and additions can you give you that extra space and function without the expense and stress of moving. Home extensions are a great way to increase the living area in your home and create a space to suit you and your family. A well designed home extension can enhance your lifestyle and create a custom made home that is relaxing, comfortable and functional and give you the home you dream of. Regardless of the type of extra space you’re looking to create such as; additional living areas, bedrooms, bathrooms, or entertaining areas – we listen to your request and create the ultimate solution for you. Our engineered designs are professionally built to make sure your extensions are built to last the test of time, so you and your family can look forward to a bright future in your revamped home. We will also arrange essential utilities like electrical wiring, plumbing and sewerage lines to connect to your new extension.
Ground and First Floor Extensions Having a wealth of knowledge in the Construction Industry, we have the skill and knowledge to offer detailed plans for your house extensions enabling us to better illustrate the scope of your project – as well as acting as a set of construction drawings – allowing you to track your build as it takes shape. Ground floor extensions and first floor additions both have their benefits, with ground floor extensions ideal if you have the space to extend outwards for an extra family room, games room, bedroom or simply an outdoor entertaining area. This may be also beneficial for the older generation with limited stairs to walk. Adding a first-floor is ideal if you have limited space for ground floor extensions, but there are many other benefits too. You’ll save time and money due to the foundations and substructure already being in place.
Ground floor and First Floor extensions are the perfect option if you’re looking for more living space. Build X offers home extensions with benefits such as:
  • Take advantage of space to extend outwards
  • Increase in property value
  • A balance between indoor and outdoor entertaining spaces
  • Add an extra family room, rumpus room or bedroom
  • Seniors and those with limited mobility can stay safe because there’s no stairs
  • Much more cost-effective – extending your home is a much cheaper alternative than moving
  • New home feeling – make your dream home even bigger and better

Property and land prices in Sydney are always changing, so it makes sense that instead of moving many are simply looking to improve their home. You may be considering a home renovation to adjust your home to the current trends or changes in your lifestyle. Conversely, maybe you are after home extension builders in Sydney to increase your living area, add a second storey extension, or construct first floor additions.

The house that you first bought may have been the perfect home when you first purchased. However, with time, your needs change. Growing children often need more room, where once bunk beds might have served. And while some members of your family enjoy entertaining guests, others may prefer getting to bed at nine o’clock.
Extending your home allows you to open up more space so that your home can be a sanctuary to do more. Allowing more rooms for privacy, and to categorise your activities in the home. And more room for storage and facilities that make your home special.

A home extension is as unique as the homeowners themselves, allowing you to shape the space to your needs rather than packing up and moving. With reputable home extension builders in Sydney, you could incorporate first floor additions such as new rooms, change your home layout with a second storey extension, and more.
