Adding a second storey to your existing home is a great way to add space without compromising your backyard! Whether you want to add additional bedrooms or living space, perhaps create a retreat, there are many things to consider, but one of the biggest factors is cost.
Before you start, you need to consider the following:
- Do you need to move out during construction? If so, you will need to arrange temporary accommodation.
- Does the ground floor require any modifications to accommodate a second storey?
- Where will the stairs be located? What space will you be losing downstairs to accommodate the stairs?
- How will the windows upstairs be placed? What type of view will you have? Will it be the brick wall of your neighbour’s house, parkland, or a busy street?
- Will your second storey overshadow yours and your neighbours’ private open space?
- Do you want the second storey to look like it’s always been part of the original house?
- What material and finish do you want to construct the addition with?
- What will the overall building height be?
- Will the new design of your home allow for functionality of both levels?
- How much structural engineering will be required?
While these factors apply to the visual appeal and functionality of your home, they also have an impact on the cost of adding a second storey.
So, what costs are involved in adding a second storey to your home?
Design and Architectural Fees
The addition to your home needs to be documented so you will need to invest in a building designer to draw up your second storey and any modifications to the ground floor.
Council and Building Permits
Most types of construction require planning and building permits which incur a fee that varies from council to council, while building surveyors will have their own fees. We will advise you of estimates of these costs for your project during our service proposal meeting.
Average Cost Per Square Metre
Often you will find that builders will price your addition per square metre. Therefore, the larger your footprint, the greater the cost.
Materials
The cost of construction materials will be impacted by the materials selected, their quality, and the amount needed (i.e., size of your addition).
Structural Engineering Requirements
Adding a second storey is basically adding another dwelling on top of your existing home.
A structural engineer will need to be engaged to add any modifications to your existing home to ensure the structural integrity of your existing walls and footings, whilst adding the support required to carry the proposed second storey addition.
