The Rise of the “Garden Grad Pad”

Over the weekend, The Sunday Times published an article titled “The kids won’t move out — so we built them an extension”, exploring how families are reshaping their homes to accommodate young adult children who are staying far longer than previous generations did.
While the piece focuses largely on extensions and major remodels, it neatly reflects conversations we have been having with prospective buyers. It is no longer only older parents moving closer to their children. Increasingly, it is families looking at the space around their home and asking: how can we create independence for our twenties-something children without pushing them into unaffordable rents?
From Granny Annexe to “Grad Pad”
The article references the idea that the traditional “granny annexe” is being replaced by the “grad pad”. With high private rents, slower wage growth and substantial student debt, many young adults are choosing — or needing — to live at home for longer.
The families featured are digging basements, extending lofts and converting outbuildings. For many households, however, there is another route: a self-contained garden annexe.
When we speak to readers, the motivation is rarely about reluctance to leave home. More often, it is about pragmatism. A young professional might be earning well but struggling to save a meaningful deposit while paying London-level rents. A recent graduate may want privacy, but not the financial pressure of a flat share. Parents, meanwhile, may be asset-rich but cash-poor, and prefer to invest in their property rather than hand over a large lump sum.
Independence Without Isolation
What appeals about a garden annexe is the balance it offers. It is separate enough to feel independent — with its own entrance, kitchen and bathroom — yet close enough to remain part of family life.

Unlike a bedroom back in the main house, a well-designed annexe can be organised much like a small apartment. Even compact studio layouts of around 25–35sqm can incorporate sleeping, living and cooking space alongside a separate shower room. Step up to 35–45sqm and you can introduce a defined bedroom and more generous living area, creating a space that feels viable for the medium term rather than a temporary fix.

Some families choose larger, two-bedroom configurations, not necessarily because they are needed now, but because they are thinking ahead. Today it might be for a graduate saving for a deposit; in the future it could become a guest suite, workspace, or even accommodation for an older relative. Flexibility is often at the heart of these conversations.

A Considered Alternative to Extending the House
The Sunday Times article highlights projects costing hundreds of thousands of pounds. For some households, extending or reconfiguring the main home is the right solution. But it is not the only one.
A garden annexe allows families to create secondary accommodation without significantly altering the original house. Many are manufactured off-site and installed in a relatively short timeframe. Depending on the design, they may be built as permanent dwellings requiring full householder planning permission and Building Regulations approval, or designed to comply with the Caravan Act and accompanied by a lawful development certificate.
For buyers we speak with, clarity around compliance is just as important as layout. They want to know that the building is properly insulated, constructed as a multi-layer structure for year-round use, and legally sound. This is not about a seasonal garden building; it is about creating a comfortable, everyday living space.
A New Shape of Multi-Generational Living
What is striking in the wider discussion is that this shift is not framed as failure. It is adaptation. In many cultures, multi-generational living has long been the norm. In the UK, we are simply rediscovering different ways to organise our homes.
Rather than parents downsizing as soon as children reach adulthood, some are rethinking how their property can evolve with them. Space in the garden becomes a practical extension of family life — separate, but connected.
If this is something your family is considering, our Garden Annexe Directory allows you to search for specialist companies working in your part of the UK and to explore projects by size, layout and approval route. The key is finding a designer who understands how to balance independence with integration, and who can guide you through the regulatory side of the process.
The “granny annexe” has not disappeared. It has simply expanded its audience. And as the housing market continues to challenge younger generations, the garden “grad pad” may become an increasingly familiar part of the modern British home.
