Optional Upgrades

EPDM Rubber Roofing

EPDM rubber roofing is a premium replacement for standard shed felt. Unlike felt, which is laid in rows and can lift over time, rubber roofing is laid in one entire sheet across the full roof — creating a seamless, watertight finish with no joins or weak points.

It comes with a 20-year manufacturer’s guarantee and has a life expectancy of over 50 years, making it one of the most durable and low-maintenance roofing options available for garden buildings.

Extra Height

The extra height upgrade increases your building’s external height to 8ft 1″ at the highest point and 7ft at the lowest point. Internally, this translates to roughly 6 inches less for headroom.

This upgrade is ideal for taller customers, buildings where you plan to add insulation and internal lining, or simply if you want a more spacious feel inside. It’s also required as standard on all UPVC and joinery range buildings to accommodate the door and window frames.

Breathable Membrane

Breathable membrane is a waterproof sheet material that lines the internal walls of your summerhouse, acting as an extra layer of protection against moisture and damp.

This is a particularly good upgrade if you’re planning to add electrics or insulation to your building, as it helps regulate moisture levels and protects the internal structure. It allows the building to breathe while keeping water out.

UPVC Windows & Doors

Our UPVC windows and doors come in anthracite grey and are double glazed as standard, giving your garden building a sleek, modern, home-quality finish. All doors come fitted with locks and keys for security.

Choose from single doors, double doors, opening windows, and fixed windows to configure the layout that works best for you. UPVC is extremely low-maintenance, highly durable, and offers excellent insulation properties.

📏 Please note: all UPVC buildings require extra height as standard.

Joinery Windows & Doors

Our joinery-style windows and doors are a great mid-range upgrade, offering a traditional timber finish with locks and keys fitted as standard. Choose from opening windows, fixed windows, double doors, and single doors.

Joinery comes single glazed as standard but can be upgraded to double glazing for improved insulation. A popular choice for customers who want a classic, high-quality look without the UPVC price tag.

Double Glazing

Double glazing can be fitted to our standard range windows and doors, replacing the single-pane toughened glass with a sealed double-glazed unit for improved thermal performance.

This is an especially useful upgrade if you’re planning to insulate your shed or summerhouse, as it significantly reduces heat loss through the glass and helps keep the building comfortable year-round.

Opening Windows

Our standard range opening windows are top-hinged and come with an internal window stay to keep them securely open or closed. Available in both long and short window sizes to suit your building’s design.

Opening windows are a great option for ventilation — especially important in the warmer months or if you’re using your summerhouse as a workspace or hobby room.

Cladded Overhang

The cladded overhang is a premium finishing touch that extends the roofline at the front of your building, creating a neat overhang clad in matching timber.

This is a popular option for customers who want to add spotlights or downlighters under the overhang for evening use — giving your summerhouse a stunning, finished look after dark.

Timber-Framed Base

A timber-framed base creates a solid, level frame for your building to be erected onto. Built from heavy-duty 4×2 CLS timbers, it’s the easiest and most popular base option — and it’s installed by our team on the day.

For maximum strength, the ground underneath should have a gradient of no more than 6 inches. This option avoids the need for expensive concrete or paving slab bases, saving you time and money.
