Telluria Classico 3930 Steel Garden Room

The Classico 3930 is the largest model in the Classico 30 series, giving you 11.6m² of genuinely usable space for storage, workshop projects, or a combined garden room with outdoor lounge area.

Does the Classico 3930 Actually Feel Spacious Inside?

Yes – the 3930 delivers 11.6m² of internal space with a 360cm internal width, giving you proper room to organise equipment, add shelving, set up a workbench, and still move around comfortably. Some garden rooms look impressive on paper but feel cramped once you start using them. This one's different. You can store equipment along one wall, create a workspace on the other, and still have breathing room. It feels more like a small outbuilding than a shed.

Why Is the 3930 Called the Largest in the Range?

The 3930 measures 388 × 298cm externally, delivering a 360 × 270cm internal footprint that genuinely makes a difference to how you use the space. That extra width changes everything. You're not forced to stack items against one wall or shuffle sideways between boxes. You can create proper zones – storage here, workspace there, perhaps a seating area in the corner.

No awkward gaps. No wasted corners. Just functional space you'll actually use.

How Tough Is the Steel Structure?

The Classico 3930 uses hot-dipped galvanised steel sheets (0.9mm thick) that resist corrosion and handle harsh weather year after year, with a roof built from 4cm insulated sandwich panels that reduce condensation and soften the drumming noise of heavy rain. This isn't flimsy metal sheeting. It's a solid, long-term structure that protects your stored items from damp conditions and stands up to whatever British weather throws at it.

The roof insulation does double duty – keeping moisture at bay whilst making the space more comfortable when you're working inside.

What Are the Exact Dimensions?

Here's the full breakdown:

• External size: 388 × 298cm
• Internal size: 360 × 270cm
• Internal floor area: 11.6m²
• Height: 219cm
• Double door opening: 175 × 196cm

Those wide double doors make life easier when you're moving bulky equipment or larger garden machinery in and out. No wrestling with awkward angles.

How Does It Handle Rain and Moisture?

The shallow 2° roof pitch works with an integrated gutter and Ø60mm outlet to channel rainwater away efficiently, whilst built-in ventilation reduces moisture build-up inside. This matters more than you might think. Less moisture means less risk of damp affecting your tools, furniture, or stored materials. When autumn storms arrive or winter drizzle sets in, the building stays dry and reliable inside.

Is It Secure Enough for Expensive Tools?

Absolutely – the Classico 3930 comes with a cylinder lock and three keys as standard, plus anchor bolts to secure it firmly to your base. You get strength and security combined in one package. Worth having if you're storing valuable garden machinery, power tools, or workshop equipment.

What Colour Options Can I Choose From?

You can pick from three contemporary finishes that suit both traditional and modern gardens:

• White (similar to RAL 9003)
• Anthracite (similar to RAL 7043)
• Light Grey (similar to RAL 7001)

Each colour gives the building a clean, modern appearance that doesn't clash with your garden's existing style.

Can I Add a Lounge Extension to the 3930?

Yes – the Classico 3930 works with larger lounge extensions, letting you create a combined storage and covered outdoor area in one structure. This setup works brilliantly if you want:

• A sheltered seating area for summer evenings
• A covered outdoor dining space
• A practical workshop plus relaxation zone
• Storage paired with entertaining space

You can position the extension to fit your garden layout, creating a flexible space that earns its keep year-round.

Who Should Consider the Classico 3930?

This model suits you if:

• You need substantial storage capacity
• You own larger garden machinery
• You want space for a proper workshop setup
• You plan to combine storage with outdoor living

It's designed for homeowners who've outgrown smaller garden buildings and need something more substantial. If you're tired of cramped sheds where everything's piled on top of everything else, this is your solution.

What Optional Extras Are Available?

You can customise your Classico 3930 with:

• Inside wall
• Perforated plate with hooks
• Aluminium floor
• Access ramp
• Electricity kit

These options let you configure the building around your specific needs, whether that's better organisation, easier access, or adding power for tools and lighting.
