Looking for a simple way to extend the usable space around your Stilla Studio? An Annex or Annex Deck can help create a more functional connection between your studio and the outdoors.
While their names are similar, they serve two different purposes. The Annex adds extra shelter and shade, while the Annex Deck creates a finished outdoor floor area. Choose either option individually or combine the two to create a covered deck that feels like a natural extension of your studio.
What Is a Stilla Annex?
The Stilla Annex is a covered awning that extends from the studio roof, creating a sheltered outdoor area immediately alongside your studio.
Measuring 1450mm deep and running the length of the studio roof, the Annex provides additional shade and weather protection without enclosing the space.
It’s a simple way to make the area outside your studio more comfortable and usable, whether you want a protected entrance, somewhere to sit outdoors or simply a little extra shelter from the elements.

What Is a Stilla Annex Deck?
The Annex Deck adds a raised outdoor floor area alongside your studio.
Also measuring 1450mm deep, the deck runs the length of the studio subfloor and is constructed from treated pine timber. It creates a defined, level outdoor platform that can be used on its own or positioned beneath the Annex to create a complete covered deck area.

Annex vs Annex Deck: What’s the Difference?
The easiest way to think about the difference is that the Annex is above you, while the Annex Deck is below you.
The Annex extends the roofline to provide shelter, while the Annex Deck extends the floor area to create an outdoor platform.
| Feature | Annex | Annex Deck |
|---|---|---|
| Covered area | Yes | No |
| Deck/floor | No | Yes |
| Adds shade and weather protection | Yes | No |
| Creates a raised outdoor floor area | No | Yes |
| Depth | 1450mm | 1450mm |
| Runs along | Length of studio roof | Length of studio subfloor |
Although they’re designed to work well together, you don’t need to choose both. Each can be added separately depending on how you want to use the area around your studio.
Why Add an Annex to Your Studio?
Adding an Annex can make the transition between your studio and backyard feel more considered while providing practical protection immediately outside the building.
Some of the benefits include:
- Extra shelter – Provides cover from light rain and direct sun.
- More shade – Creates a more comfortable outdoor area during warmer weather.
- A covered entry – Adds protection around the doorway while creating a more defined entrance.
- More usable space – Makes the area directly outside your studio more practical for everyday use.
- Flexible configuration – Use the Annex on its own or combine it with an Annex Deck.
Why Add an Annex Deck?
If you’re looking for a finished outdoor platform rather than overhead shelter, the Annex Deck may be the better choice.
It provides a dedicated area to step out onto and helps visually extend your studio beyond its internal floor space.
Benefits include:
- Creates a level outdoor area – Provides a dedicated platform immediately outside your studio.
- Treated pine construction – Creates a practical timber surface designed for outdoor use.
- Adds a more complete finish – Helps the studio feel considered from both the inside and outside.
- Works independently – Choose the deck without an Annex if you prefer an open outdoor area.
- Pairs naturally with the Annex – Combine the two to create a sheltered outdoor deck.
Can You Combine an Annex and Annex Deck?
Yes. Combining the two gives you the benefits of both options.
Studio + Annex
This gives you a covered outdoor area alongside your studio without adding a deck.
It can be a great choice if you want additional shade and shelter without a raised outdoor platform.
Studio + Annex Deck
This creates a raised treated pine deck alongside the studio without overhead cover.
It’s ideal if your priority is creating a defined outdoor platform while keeping the area open.
Studio + Annex + Annex Deck
Combining both options creates a covered deck area, with the Annex providing shelter overhead and the Annex Deck creating a finished outdoor platform underneath.

Which Option Is Right for Your Stilla Studio?
The right setup depends on how you plan to use your studio and the surrounding outdoor space.
If you mainly want shade and weather protection, consider the Annex.
If you want a defined outdoor floor area, the Annex Deck may be all you need.
If you want both, combining the Annex and Annex Deck creates a covered outdoor deck that extends the usable area around your studio.
Both options are sized to suit the selected studio. The final length therefore depends on your studio model: the Annex follows the length of the studio roof, while the Annex Deck follows the length of the studio subfloor.
