Funding guide
More ways to fund a garden room than you might think.
Most customers discover there are simpler, more affordable routes to fund a garden room than traditional retail finance — whether you’re creating a home office, gym, studio or a space that earns its keep.
Why customers invest
The reasons behind the spend.
Before considering how to fund a project of this size, it helps to revisit why so many UK homeowners view a garden room as a sound investment rather than a discretionary purchase.
- Save time
No commute. Reclaim 6–10 hours every week.
- Create space
Add a room without the cost of an extension or moving home.
- Improve focus
A dedicated workspace, separate from family life.
- Enhance lifestyle
A gym, studio or wellness space — five steps from the back door.
- Property appeal
A premium outdoor living space buyers notice.
The four common routes
Most projects are funded one of four ways.
Few customers use just one. A combination of savings and a small loan, or home equity topped up with personal savings, is far more common than people realise.
Simplest route
Personal bank loan
- Fixed monthly repayments
- Quick decision in most cases
- No charge over your home
Best for
Mid-range projects when savings aren't earmarked for the build.
Home equity
- Potentially lower monthly payments
- Longer repayment terms
- Borrow against existing equity
Best for
Larger projects — often used alongside savings to top up.
Business funding
- Suitable when the room earns income
- May offer additional tax considerations
- Asset finance routes available
Best for
Offices, studios, therapy rooms and commercial spaces.
Arden & Oak does not arrange or broker finance. We’ve outlined these routes so you can have an informed conversation with your bank, accountant or mortgage adviser.
The earning garden room
Could your garden room support your business?
Many Arden & Oak buildings earn their keep. When a room generates income — even a small side practice — it can change the conversation around funding entirely. Below are common income-generating uses we see in real projects.
- Home office
- Yoga studio
- Pilates studio
- Therapy room
- Beauty room
- Personal training studio
- Golf simulator coaching
- Photography studio
- Music studio
- Content creation studio
Important
Tax treatment depends on your business structure (sole trader, partnership, limited company), how exclusively the space is used for business, and your individual circumstances. Speak to a qualified accountant before relying on any tax treatment.
Worth a conversation
Understanding the tax picture.
The following is a high-level overview — not advice. Tax rules change, and your situation is unique. We strongly recommend speaking to a qualified accountant before making decisions based on potential tax treatment.
Home offices
Sole traders and limited company directors sometimes claim a proportion of running costs related to a home office. Capital expenditure on the structure is treated differently depending on how the building is used.
Wellness businesses
Yoga teachers, therapists and personal trainers often run sessions from a dedicated garden studio. Where the space is wholly used for business, services and contents (heating, glazing, electrics) may qualify for capital allowances.
Creative studios
Photographers, musicians and content creators sometimes treat the building as a business asset. Acoustic treatments, lighting rigs and integrated joinery may be claimable depending on circumstances.
Commercial-use buildings
For rooms used wholly for business by a limited company, VAT on the build cost may be reclaimable. There can be implications on Capital Gains tax exemption on the main residence — a careful conversation with an accountant is essential.

Frequently asked
Funding questions, plainly answered.
Do Arden & Oak offer finance?
No — we are a garden room manufacturer, not a finance broker. We don't arrange retail finance, partner with lenders or earn commission on funding. We've put this guide together so customers can make a confident, informed decision in conversation with their bank or accountant.
Can I use a personal loan for a garden room?
Yes — personal loans are one of the most common ways customers fund a garden room in the £15k–£40k range. They're widely available from high street banks, decisions are typically fast, and the loan isn't secured against your home. Compare APRs and total repayable amount before committing.
Can a garden room be used as a business expense?
It can — but only where the building is used wholly and exclusively for business purposes. The structure itself usually isn't deductible, but services and contents (electrics, heating, glazing, integrated joinery) often are. Tax treatment depends on your business structure. Speak to a qualified accountant.
Can my business pay for my garden room?
If your business is a limited company and the building is genuinely used for business, the company can pay. There are implications around Benefit in Kind, VAT recovery and Capital Gains exemption on your main residence that need to be understood up-front. An accountant should walk you through your specific scenario before you place an order.
Is a garden room cheaper than an extension?
Usually yes. A like-for-like single-storey rear extension typically starts at around £30,000–£50,000 and rises quickly once kitchens, structural works and planning are involved. A premium SIP-built garden room of similar floor area is often delivered turn-key for £20,000–£45,000, with no impact on your main building, no planning required in most cases, and a 6–8 week timeline.
What's a sensible deposit?
Most Arden & Oak projects start with a 10% deposit on order. A further 40% is staged at factory production start, 40% on delivery to site, and the final 10% on completion sign-off. That structure works well alongside any of the four funding routes covered in this guide.
