Why portable buildings?

Portable buildings in Adelaide provide the unique advantage of flexibility. They proffer that extra space that is so sorely needed by many and can come in whatever shape, size, or form that satisfies those needs. From offices to apartments to storage space, the options and usage of portable buildings are vast.

Portability is yet another key element to consider. Since these types of buildings do not routinely require a foundation and can simply be situated on a flat surface of compacted ground or concrete, relocation is always a viable option. They can easily be moved to new premises or a different location on the existing site as your needs change and develop.

The economic aspect and affordability of portable buildings is a quality that cannot be ignored. We are able to keep costs low for our portable buildings as they are prefabricated and constructed in our factory rather than on-site. While the guaranteed durability of our portable buildings ensures it to be a long-lasting investment for years to come.

Its convenience and expeditiousness cannot be overstated. As portable buildings come pre-constructed they are easily installed in the desired location. This means a quicker set-up time and a shorter waiting period to achieve the extra space or accommodation you require.

Granny Flats

A granny flat, or accessory dwelling unit (ADU), is a self-contained living area typically located on the grounds of a larger property. It is usually called a ‘granny unit’ as it is increasingly becoming a popular way to house elderly relatives in a multigenerational housing scheme. However, the use of these granny flats is not limited to that.

Granny flats are also referred to as a casita, garden cottage, bonus unit, carriage unit, and more. Homeowners may choose to use it as a home office, a guest room for visiting family and friends, or an additional room for nannies. Some utilize it to earn extra income by renting out the space to tenants, as well.

As the prevalence of granny flats in Adelaide continues to rise they also become smart investments in developing your property. Realtors and those in the business of property are already reporting that granny flats work as a good selling point. They can make a property more of an attractive buy while also improving its worth.

The advantage of installing a portable building from Outback Portable Buildings as your granny flat is the ability to build and construct it according to your needs and preferences. This includes selecting the specific amenities a tenant or family member requires to be comfortable, such as kitchen facilities or devices for the aged.

Capitalizing on portable buildings also means a lower barrier to entry in terms of regulation. A common problem for granny flats is the complicated zoning laws, building restrictions, and municipal statutes that are applied to construction. With portable buildings, it is generally easier to attain permission or authorization for installation as there is no construction required on-site.

New construction tends to be on the pricier side, as well. Expensive costs present themselves as another obstacle to adding a granny flat to your property. But the comparatively cheaper option of portable buildings makes having a granny flat more viable.
