Don’t move, build: Rather than relocating to a larger home, consider first floor additions as it may be the more economical option.

Ground Floor Extensions


You will be blown away at some of our previous work that we have done and how we can transform the ground floor of your home. If you have extra land or a large backyard that you do not utilise, and would prefer to make better use out of it, then a ground floor extension is a great option for you.


You will be able to have:


  A larger living/dining space

  An extended master bedroom

  Spare bedroom

  Additional outdoor living area

  A Granny Flat



Benefits of Ground Floor Extensions


Accessibility: For the elder and those who have difficulty with stairs, ground floor extensions can allow you to have room whilst being accessible to all bodies.
The same front: You are able to build and extend your home from the back while maintaining the same, beautiful street view of your home.
Relocate Rooms: You will be able to relocate main areas of your home to where it makes sense. If an extension allows you to have an open plan living/dining space however your current kitchen is boxed in, you will be able to create a kitchen in the new space to open it to the rest of the home. Following that, the previous kitchen space can be used as a separate room.


Many residents across the Northern Beaches and North Shore of Sydney are growing their homes with ground floor extensions. Have the functional and impeccably designed home you have always desired. Contact the builders and designers of Spannenberg& Son.



Home Renovations


If you reside in a dated home in the Northern Beaches, you may want to consider completing a renovation to part or all of your house. Rather than relocating, you can have an exceptionally built and contemporary redesign of your current home. We narrow down to the finest details, leaving you blown away at your very own property. If you are committed to renovating your home but you do not know where to start, our team is exceptionally skilled at helping you understand your home in a way you would not have considered initially.


We knock down walls, replace windows, roofs, gutters and carry out complete kitchen and bathroom renovations. If there is an aspect of your home that frustrates you or is impractical, renovating your home can be the solution to your problems. For example, if your home is situated in a way that it is dark and the interior is closed in, we are able to add light through new windows or glass sliding/folding doors leading to the backyard. We are here to help you from start to finish.
