Multi-Generational Home Extensions in Melbourne
ADD VALUE TO YOUR FAMILY HOME AND CREATE SPACE FOR YOUR MULTI-GENERATIONAL LIVING EXPERT EXTENSION BUILDERS


There has been a rise in young adults living at home for longer, parents looking after adult children in need, grandparents moving in to help look after grandchildren for working adults or needing care assistance, or long-term visiting family or friends due to long-distance living. These changes have resulted in multiple generations living together under the same roof.
Our multi-generational home extensions go beyond the practicality of two or more generations living together. We focus on creating separate living areas that integrate with the existing house structure, preserving character and family memories for multi-generational living. Picture a large living space that fits every family member, mornings in a newly designed kitchen, or gatherings with the whole family in an expansive entertainment space.
As Melbourne’s multi-generational home design specialists, our in-house design team works closely with multi-generational families, crafting functional layouts such as separate entrances that maximise space and value for young families with growing children, all within your budget. No need for costly external architects – we do it all!

WHY MULTI-GENERATIONAL HOMES ARE AN ATTRACTIVE OPTION
The benefits of having multiple family members living under one roof depend on your family values. Are you looking to create a dual occupancy home to cater for an adult child living at home longer or to have additional support for your kids? When building a ground floor extension or adding a second storey to your home to cater for a growing family, you may benefit from stronger family bonds, childcare support and the potential to save money. Creating a larger home to cater for multiple generations increases your living space square footage.
Thanks to our dual living design experts, multi-generational home extensions blend perfectly with your existing home, boosting its value and curb appeal for future resale. Extensions Unlimited has been creating extra space for Melbourne families just like yours since 1994.

MULTI-GENERATIONAL HOMES VS GRANNY FLATS
Multi-generational house extensions focus on renovating existing living spaces to cater to all family members within the main house. Home designs for multiple generations depend on the level of independence wanted. Will you share meals and household chores or would you prefer to live independently but under one roof? We will help you design the best way to add living rooms bedrooms and bathrooms or powder rooms to the main house to accommodate all preferences and family sizes.
A granny flat is a self-contained dwelling separate from the main house designed for grandparents who need assistance but want independence or for young adults who are struggling to get into the housing market. A granny flat design allows for separate living spaces with its own kitchen, bathroom and bedroom, offering greater privacy. A granny flat construction may present limitations compared to expanding the main family home.
An expert house extension company like Extensions Unlimited is a great choice for your multi-generational house extension because our communication is impeccable, so there is no surprise extra costs during construction.
