The Shell Concept: You’re in Control
Every bespoke garden office begins as a Shell Building that you can customise to suit your taste and budget. This unique approach allows you to choose your layout, insulation levels, and final finishes—meaning you only pay for the features you truly need.

- Felt tile roofing – available in black, grey red or green (upgrade options available)
- Roof pitch of 20 degree’s

- Fully Assembled, with delivery, erection, and VAT included

Groundwork
Any ground works required for your building will be listed separately within your quotation. Any extra ground works can be quoted for separately.

Depending on how you plan to use your building, we offer a range of flooring choices, Standard Laminate Flooring or Engineered Oak. Priced Upon Request.
* An estimation of cost can be quoted once we have either carried out a site visit or seen photographs. We will only remove the building, not the contents. If the building has internal cladding there will be an additional cost to remove. Please note that legally we cannot handle & remove asbestos. But we can put you in touch with someone who can!
Frequently Asked Questions
Does a garden office add value?
Yes, a well-designed garden office can add value to your property. Buyers see it as a flexible extra room, perfect for remote working or a dedicated workspace separate from the main home. A bespoke timber office from Phoenix Timber Buildings is built to last, making it an attractive investment.
Do you need planning permission for a garden office?
Most garden offices fall under permitted development, provided they meet certain size and placement rules. If your design goes beyond these limits, planning permission may be required. Our complimentary site visit helps you understand exactly what’s possible in your space.
How much does a garden office cost?
All of our offices are bespoke, so the price depends on your chosen size and specification. We begin with a shell structure that you can upgrade to suit your needs, with every adjustment costed individually. This way, you’re always in control of your budget.
How to get Wi-Fi in a garden office?
There are several ways to connect your garden office, from extending your home Wi-Fi with boosters to installing a dedicated cable or router. Your Project Manager can advise on the best solution based on the location of your office and how you plan to use it.
