Granny annexes have become increasingly popular as a way to accommodate elderly family members while providing them with their own space and independence

In an era where multi-generational living is becoming increasingly popular, the concept of granny annexes is gaining traction as a means to provide comfort and convenience to elderly family members


A garden annexe can be an excellent addition to any property. It can be a versatile and cost-effective way to add extra living space, providing a comfortable place to accommodate guests or work as a home office or gym. However, before you start building, it's essential to consider planning permission.

Granny annexes are not just for the elderly but can also be a way to help a son or daughter get on the housing ladder. At Vita Modular we offer a variety of permanent, liveable solutions to keep family members close without disrupting their privacy or independence.
