Second Storey Additions

Second storey additions (or first floor additions) can be a smart way to capitalise on limited site space. They can be a cost-effective alternative that gives the owner better value for money than any other home extension or addition. Planning to build a home extension when you need to accommodate a growing family, or as part of a restyle to your house, takes an experienced builder to ensure you receive the benefits it can deliver.

Family Homes has over 30 years experience building quality second storey additions – North Shore residents can rest assured that we’ll get the job right. We’ll take care of the entire process from concept to completion including designing, planning, construction, and ensuring that you are kept in the loop through consultations at every stage.

Every project Family Home Designers and Builders undertakes is a custom project, whether they are second storey additions, ground floor additions, or major interior renovations, no two projects are the same. What always stays the same is our focus on quality standards and the quickest, smoothest path to completion for every client.


We have been helping our clients with second storey additions in Sydney realise their home renovation dreams for 30 years. During this time, we have consistently provided innovative yet practical designs, excellent customer service, quality products and speedy construction. Extending a house to a second/double storey in Sydney can be a daunting prospect. There are a lot of things to consider like removal of roofs, plumbing, potential structural issues and many more. That is not to say that it’s not a big job, but with the right company and council approved builders in Sydney, it is entirely possible and can be a pleasant experience.

Building a Second Storey Extension – How it Works

Most first floor additions involve adding between 2-4 bedrooms and one bathroom on top of the existing dwelling. Other families prefer adding an additional living space upstairs, particularly when there are good views which is often the case in the North Shore. Whatever your goals are, the award-winning team at Family Home can help execute your vision.

Our process starts with a consultation where we discuss your requirements and best solutions, and then design the layout tailored to your needs as well as the finishes you would like incorporated. You’ll then be given a proposal with design sketches, specifications, budget, and timeframe. If you approve, we’ll move forward with the agreements and approvals before commencing construction.

Featured Project – Second Storey Addition at St Ives

Our clients from St Ives needed two additional bedrooms and office space, as well as a new kitchen layout. They didn’t want to encroach on the backyard too much, so we decided that a second storey addition would be the best solution. We built the large kitchen and family room at ground level overlooking the pool.
