Blue Horizon Projects


Double Storey Extensions Central Coast homeowners can undertake to enhance the functionality and value of their home. Blue Horizon Projects are specialists in double storey extensions. Based on the stunning Central Coast of NSW, we have been renovating and adding extensions to clients homes for many years. This not only gives the homeowner much-needed space for their growing family or changing needs, but also increases the value of their property. The Central Coast housing market is booming and a double storey extension may make a huge difference to the saleability of your home.

Many homeowners are choosing to add extensions to their existing home, rather than opting to sell and buy a new home. The market is so explosive on the Central Coast in 2021, that many families have been caught selling their home well above the asking price and finding themselves unable to buy in the area they love because of such high demand. Before you consider selling because your have outgrown your home, or you needs have changed, contact the team at Blue Horizon Projects to discuss how we can build you a double storey extension that will enhance your home to suit your needs.


Blue Horizon Projects has the experience to ensure your double storey extension looks fantastic and enhances your living space. We pride ourselves on delivering your project on time and on budget and work with you every step of the way to bring your ultimate vision to life.

Many of our clients choose to upsize their home rather move. Some clients are looking to add value by optimising available space in a useful manner such as adding an extra garage, or double storey to include a parent or teenage retreat. We have been involved in many double storey extensions over the years and know how to maximise your space and improve the functionality of your home.


A double storey extension is a great way to add space to your Central Coast property. Not only does it add often much-needed space, but it also adds value and overhauls your current residence to suit the needs of you and your family.

The double storey extension has a few added benefits for your home. You create another internal living space and have the benefit of a modern, new look to your home without having to say goodbye to the Central Coast suburb you love.

Adding a double storey extension is a perfect solution if you don’t want to move home, buy another property and move your kids to a new school.

The Benefits Include:

Retaining the size of your yard

Getting a double storey extension added to your home has no impact on your land area, meaning you don’t lose valuable yard space. You don’t have to sacrifice any backyard space to do so. You already have a structure to work on and you can keep your yard space exactly as it is.

Add value to your home

The double storey extension adds value to your home. The perception of a double storey home compared to a single storey home that it is more expensive. The perceived value is different to that of a single storey home.

Future proof your home

Adding a second storey addition to your home is a great way of future proofing your home. We don’t know what the future holds so preparing for it is a great step. Many families choose to extend their homes up a level to ensure their home will accommodate their growing family, even in laws.

Capitalise on views

The Central Coast has some stunning locations. Beaches, National Parks and beautiful waterways. Adding another storey to your home is a great way to take advantage of the views.

The most popular reasons for double storey renovations

The two most popular reasons for going with a double storey renovation include a parents retreat or creating a childrens/ teenage “hang out” space. If parents don’t specifically want to be upstairs (thinking of old age) they can add some kids bedrooms upstairs instead. There are many ways in which Blue Horizon Projects can add more space to your home.

Parents Retreat

A parents retreat generally consists of a master suite with ensuite, walk in robe and living room. The benefit of having a parents retreat upstairs is it gives you space to unwind plus adds another living area to your home.

Teenage Hang out

The great thing about having a separate storey for your children/ teenagers is that they have their own TV and games area and can relax with their friends and not annoy other members of the household.
