Dylan and his team renovated my bathroom, laundry and kitchen in my unit. His team are excellent and I couldn’t be happier with the final product.

I was particularly happy with the quality of cabinet making, tiling in the bathroom, and painting.

Dylan is very responsive, trustworthy and a nice bloke to deal with. When problems arise (as they inevitably will) he tackles them quickly and without fuss. Highly recommended.

House extensions enable you to add to your existing structure to either enlarge existing rooms or create completely new ones. Depending on how the house extension is designed it can also create changes to your floor layouts to improve the usability of existing living areas in your home.

A house extension can be combined with a bathroom renovation or kitchen remodel to create a practically new home without needing to get a new mortgage or re-enter the property market. Alternatively an extension can simply be to create extra accomodation so you can rent a room on Airbnb to earn an income.

Why would you do a house extension?

If you want a house extension contractor in Sydney then you are not alone, there are lots of reasons why people do a house extension these days as for many it is a more affordable option & smarter way to create a better living space.

1. Create more space

The simplest reason people do house extensions is to add more space to their home. This could be for another bedroom, billiard table room, Airbnb guest accomodation or to create a studio.

2. You love the area

You might be living in a location that you absolutely love, so simply doing a house extension in Sydney can be the most logical way to get even more enjoyment out of the home you live in. Renovating lets you add value & enjoy what you love.

3. Improving practicality

Most homes in Sydney that get house extensions are because they were build in the 1960’s or 70’s where the floor plans were very cramped and there wasn’t much light or ventilation available. A house extension and room renovation can open up your home and your living spaces.

4. Kids grow up or move out

As your kids get bigger you might need more space or more bedrooms, so that is a great reason to add a house extension. If the kids are old enough to move out, adding extra space can let you add a bathroom or home theatre room to your home.

5. Improve value

Adding rooms or making existing living spaces larger in your home can add value to your property. This can be a smarter investment choice compared to buying another property.

6. Less stress and hassle

Renovating your existing home can be less stress and hassle compared to trying to buy a new property. With record home values in Sydney it is increasingly difficult for people to buy a home so they will add an extension instead.

Frequently Asked Questions

The most frequent questions asked about HOME RENOVATION IDEAS.

Can a home theatre room be added as a home extension?

Yes you can create any type of living space you want when you add a home extension. The new space could be a new home theatre room to watch Netflix or another bedroom, the choice is up to you.

Can a house extension be a kitchen or bathroom?

Yes you can do a house extension that includes kitchen, bathroom or other practical living spaces. Depending on your floor plan you can even extend what you have to make it even bigger.

Is it cheaper to renovate or rebuild?

In most cases it will be cheaper to renovate or remodel parts of your house than it would be to completely rebuild.

Each method has its pros and cons but if you are on a tight budget then you can use some clever renovating techniques to keep costs in control, but give your home a new look.

Normally it can be 20-30% more to do a rebuild vs renovating.

How much do renovations cost in Australia?

According to Hi Pages the average cost to renovate a living room is between $10,000 and $15,000. Although this average changes quickly if the flooring is going to be changed, walls moved or expensive materials are used.

Bathrooms & kitchens will typically cost between $15,000 and $30,000 to do complete room renovations but these rooms will also add the most value to a property compared to adding a garage or doing landscaping.

Where do you start when renovating a house?

We often joke and say the best place to start is the front door and work your way back from there. Although, on a more serious note the first place to start when renovating your house is to get renovation ideas. You have to use those ideas to create a very clear renovation brief that will cover the main goals, budget, timeframe and purpose of your project. 

This will mean that all your decisions are based around achieving a goal with some very clear parameters to follow. This will then dictate where you need to start before you begin renovating.

What are the types of renovation?

Generally speaking there are a few types of renovations that many people will consider. There is no definitive list as every situation is different but most common are;

  • Bathroom renovations
  • Kitchen renovations
  • First floor additions
  • Room extensions
  • Renovation remodels or makeovers


How can I renovate my house cheaply?

The first thing to consider is there really isn’t anything cheap about doing a house renovation properly. You could renovate your house cheaply by becoming a licensed builder and doing it all yourself, although most people don’t have the time or desire to do this.

Renovations can be done simply if they focus on changing the existing elements within a house for example re-painting can be a cheap way to renovate with a fresh coat of paint giving a new room or living area a fresh look. Other ways to renovate cheaply might be to change things like light fittings, tap fixtures, benchtops or even the flooring to freshen up a room.

Which home improvements add most value?

In most cases improving your bathroom or kitchen can add the most value to your home. Although this will all depend on how much you are prepared to spend, the value of your property & its location. 

Spending over $50,000 on a bathroom renovation for a rental property bathroom will probably not make much financial sense considering its intended use. Although adding parking or an extra room to an inner-city property could be extremely beneficial.

So there is no single improvement that will add the most value, it becomes more important to consider the context of the renovation and what you are trying to achieve with it.

Can you renovate a house for $100K?

Well for sure you can spend $20K, $50K or $100K to renovate a house although whether that is a sensible amount to spent will depend on your situation. If it is retirement time & there are no other concerns beyond having an enjoyable life then it won’t matter too much what is spent.

Although, typically most people are trying to renovate a house with an eye on increasing its value, therefore you have to be careful how much is spent. There will be a point where the value of any renovations won’t proportionally add value to your home. Generally speaking if the property is worth $500,000 then you should aim to spend around $50,000 and focus on the big areas like the kitchen and bathroom.

How do you renovate an old house?

Renovating an old house isn’t as simple as it seems. There are many properties in Sydney which are heritage listed so the first step is to check your local council requirements and get help from someone like Sydney Heritage Consultants to make sure any alterations are in accordance with local requirements.

If it is just an older home the first thing to have checked is to make sure all the structural elements are sound before planning your renovation. Older full brick homes are typically more difficult to work with compared to timber veneer houses like the ones in Merrylands.
