How Much Does an Attic Conversion Cost?
Attic conversions can broadly be placed into three categories:
- Converting an unused attic into a useable storage space
- Renovating an attic into a habitable room
- Extending an attic into a habitable room or living area.
Each of the above comes with their own price bracket. The cost of an attic conversion is little different from a regular home renovation, in that the time and labour cost, together will the materials required by the home owner, will form the largest part of the cost. Nonetheless there are some unique aspects which can influence the price to a greater or less degree.
Basic Storage Attic
For between $3,000 and $5,000, an unused attic can be turned into usable storage space. This mainly involved lining the ceiling rafters with floor boards, and installing a retractable access ladder. Supporting timbers may also need to be installed, to ensure that the storage area will have sufficient load bearing capacity. From here, the options are many. A “dust proof” storage attic includes the construction of plywood lined walls, and will cost at least double the cost of the storage attic. If you want “deluxe storage” then you should expect to pay at least $20,000 for the project.
Habitable Attic Rooms
A liveable or “habitable” attic room comes with its own set of requirements, and you can expect to pay significantly more. Specifically, a habitable room is required to have an approved staircase, and windows are required for adequate natural light and ventilation. Prices are between $20,000 and $60,000 which will fulfil the basic mandatory requirements, but won’t include any luxury extras.
Deluxe Attic Conversions
The word “Deluxe” says it all, and as with most luxuries, the options are endless if you’re willing to pay for it. Depending on size and the required optional extra, turning an unused attic space into luxurious living quarters will cost anything between $60,000 and $120,000. If space allows, you can for example opt for a bedroom with ensuite, with an adjoining living area.
Here, the size, shape, lighting, floor finishes and any special decorative and functional features will all play a part in the final quote you receive from your builder.
