A granny annexe can change more than your home.
It can change how your family lives.
Whether you’re planning for an older relative, giving teenagers more independence, or creating a private guest space, a well-designed annexe can offer flexibility without moving house.
But before you start building, there are a few things to consider:
• What type of annexe suits your property?
• Will you need planning permission?
• What building regulations apply?
• How much will the project cost?
• What layout will make the space work best?
From compact garden annexes to permanent brick-built spaces, there are plenty of options.
And the right design can give you much more than an extra room.
It can provide independence, privacy, flexibility and long-term value.
At Greenway Associates, we help homeowners design granny annexes, navigate planning requirements and create spaces that work for the whole family.
