Complete Home Renovations is an Auckland-based renovations company that specialises in renovations and home extensions in Auckland and the greater Auckland area. These extensions can include extra bathrooms, bedrooms, sleepouts, outdoor living areas, basement conversions, second storeys, sunrooms, garages and much more.

Types Of House Extensions Available in Auckland

Complete Home Renovations offers a comprehensive one-stop-shop solution for all your house extension and renovation requirements including plumbing, electrics, complete design, project management and even financial planning. We offer quality materials, design experience, workmanship and delivery of beautiful and functional extensions for any house size. The types of house extensions you can explore include (but are not limited to):
A simple extension very popular in Auckland homes, offering a covered or open space which can make a big change to the overall look of your home. Coming home is made much more inviting with a gorgeous classic or modern porch to fit your home’s existing aesthetic.
This very popular home extension can bring a very traditional British feel to a home or can be easily designed to add sleek lines to a brand new and modern living space that soaks up the sun. Used originally for horticulture, conservatories are the perfect environment to have a green thumb and fill with plants for an outdoors experience without having to leave your home! It’s the perfect living space all year round, which makes it such a popular extension in Auckland where the weather is unpredictable.
A sunroom is a gorgeous extension choice to make your living space, office or dining area bigger, soaking up more light and making your house feel airy and big.
Switching your house configuration around and adding small features on is a creative way of revinenting your home without having to move! This can be a fairly big job, depending on what you want to redesign, but it will still most likely cost less than moving house.
It’s not a secret that adding a garage to your Auckland property adds value to it, but converting a garage is another great option for people wanting to extend their living space into already existing walls if they don’t need their garage space for cars! Garages can be converted into pretty much anything you can think of including bedrooms, laundries, bathrooms, granny flats, games rooms, offices, workshops and more. What you can do with a garage conversion is almost endless.
Like with garage conversions, converting your basement is another popular extension option for Auckland homes. Reimagining the space as something functional adds value to your property.
