Granny flats have become popular due to their relative cost. They are well-liked by astute homeowners needing additional space and astute investors seeking profitable endeavours. One-bedroom granny flats are the most affordable due to their exceptionally small size.
A study of nine businesses in Sydney and Newcastle found that the whole turn-key cost of a one-bedroom granny apartment at Pillar Build Granny Flats ranges from $120,000 to $160,000. This includes construction, standard features, and all site-related expenditures, design fees, and approval fees.

This deal is probably too good to be true if you come across a granny flat builder promoting an especially low price (we’ve seen figures as low as $80,000). What appears to be a good deal could quickly develop into a budget-busting pile of hidden expenses or a sacrifice in quality due to cut corners.

Tips for Making the Most of Your Space

Make Use of Vertical Space: Making the most of vertical space is an excellent idea to increase the functionality of your granny flat without eating into the floor space. The following are some such ideas:

Tall Storage Units: These are built-in tall cupboards, wardrobes, and bookcases that extend right up to the ceiling. In addition to serving the purpose of ample storage, they draw one’s eyes upwards to give an illusion of space and height.

Shelving: Place shelves on the walls for books, knickknacks, and other items. Floating shelves work well in this regard since they save floor space while providing storage.

Overhead Cabinets: In the kitchen and bathroom, overhead cabinets are needed to store stuff that is not used every day but still needs to be easily accessible.

Hanging storage solutions range from hooks and hanging storage for cookware, pans, and utensils in the kitchen to coats and other accessories in the living area. These help keep items neatly out of the way and not on countertops or floors.
