Custom Glass & Aluminium Garden Rooms

Glass garden room attached to a house with sliding doors

AVC Build garden rooms are made to the confirmed dimensions of the individual property. A structure can be attached directly to the house to create a protected outdoor glass room beside an existing patio, or designed as a freestanding enclosure elsewhere in the garden.

The enclosure can combine clear or frosted fixed glass, sliding glass door systems, aluminium privacy walls and compatible polycarbonate panels. Roof choice, post positions, drainage and the supporting base are specified around the final dimensions and site conditions.

The modular aluminium system also allows selected compatible elements to be considered later, although planned glazing, doors, shading, lighting and heating are best discussed during the initial design.

Freestanding Glass Garden Rooms

A freestanding garden room uses its own supporting posts and does not rely on attachment to the house. It can suit a separate seating or dining area where the site provides suitable foundations and access for installation.

The final enclosure can remain partly open or use side walls and glazing according to the intended level of wind and rain protection.

Glass Walls, Sliding Doors and Roof Options

Sliding Glass Door Systems

Sliding glass systems allow large sections of the garden room to be opened for access and ventilation, then closed when additional protection from wind and rain is required. They are particularly useful for a glass room attached to the house where the client wants wide views into the garden without permanently closing the space.

The lower tracks require a level and stable base. Floor levels and track positions should therefore be coordinated before installation.

Fixed Glass and Privacy Side Walls

Fixed clear or frosted glazing can close selected sides while maintaining natural light. Aluminium privacy walls can be combined with glass where one side requires more screening from neighbouring properties, wind or direct views.

Glass, Polycarbonate and Opaque Roof Options

A garden room with a glass roof provides maximum transparency and daylight. Polycarbonate is lighter and can be selected in clear or opal finishes, while compatible opaque roofing can provide more shade and privacy where transparency is not the priority.

The roof material affects the supporting layout, roof fall, drainage and final project cost, so it is confirmed as part of the detailed quotation.


Preparing the Installation Area

Base, Foundations and Sliding-Glass Tracks

The preparation required depends on the existing patio, the supporting post positions and the selected enclosure. A suitable concrete base can be used where it is appropriate for the fixing system, while other sites may require dedicated foundations.

A level and accurately finished surface is especially important where sliding glass door systems are planned because the lower tracks must remain straight and stable. Drainage, floor levels, wall connections and installation access are checked before the final specification is confirmed.

Qualifying aluminium garden-room structures installed by AVC Build are supplied with a written 10-year structural warranty.

“We were very pleased with our purchase of a garden room from AVC Build! We chose the attached model with all-glass side panels and a huge sliding door. It feels like sitting in a garden, but without the dampness and wind. The aluminium is of incredible quality, and the room retains heat much better than you’d think given the amount of glass. It’s a truly cosy spot, even when it’s pouring outside.”

“Let me say a few words about AVC Build. I’m extremely satisfied with the overall craftsmanship and quality of the work. The attention to detail is clear in every aspect, from the clean lines to the solid construction. The aluminium structure feels incredibly durable and well-finished, giving the entire space a modern and high-end look. What really stands out is how sturdy and precisely installed everything is — it not only looks great but also feels built to last. The materials used are clearly of high quality, and the workmanship reflects a high level of skill and care. Overall, I couldn’t be happier with the result. It has completely transformed the space into something both functional and visually impressive. Highly recommended.”

Frequently Asked Questions About Glass & Aluminium Garden Rooms

How much does a garden room cost in Ireland?
The cost depends on the dimensions, wall-mounted or freestanding layout, roof material, glazing, sliding glass systems and additional side walls or equipment. Use the calculator for an initial structure estimate. The final quotation is confirmed after the complete specification, foundations, site access and installation conditions have been reviewed.
Can a glass garden room be attached to the house?
Yes. A wall-mounted garden room can be attached beside the house to enclose an existing patio or create a protected outdoor glass room. The wall construction, fixing positions, roof fall, drainage and floor level are checked before the final layout is confirmed.
Can the garden room be freestanding?
Yes. Freestanding garden rooms use their own supporting posts and can be positioned independently from the house where suitable foundations, access and ground conditions are available.
Can a garden room have sliding glass doors?
Yes. Sliding glass door systems are one of the main enclosure options. They can create wide glazed openings while allowing sections of the room to be opened for ventilation and access. A stable and level base is required for the lower tracks.
Which roof materials are available?
Depending on the selected system, garden rooms can use laminated safety glass, polycarbonate or compatible opaque roof materials. Glass provides maximum transparency, polycarbonate is lighter and available in clear or opal finishes, while opaque coverings provide more shade and privacy.
Can side walls, shading, lighting or heating be added later?
Many compatible elements can be reviewed later because the aluminium system is modular. It is still best to discuss planned additions during the initial design so post positions, foundations, drainage, floor levels and electrical preparation can be coordinated correctly.
What base is required for sliding glass systems?
Sliding glass lower tracks require a level, stable and accurately prepared base. Existing concrete can be suitable where it meets the fixing and level requirements; otherwise additional preparation may be needed before installation.
Do I need planning permission for a garden room in Ireland?
Planning requirements depend on the type of structure, dimensions, height, position, previous development on the property and intended use. The property owner should confirm the requirements for the individual project with the relevant local authority or a qualified planning professional before work begins.
Do you supply and install garden rooms throughout Ireland?
Yes. AVC Build supplies made-to-measure glass and aluminium garden rooms throughout Ireland and provides professional installation subject to project location, site access and the required preparation. These details are confirmed during quotation.
What warranty is provided?
Qualifying aluminium garden-room structures installed by AVC Build are supplied with a written 10-year structural warranty. Coverage for glazing, roof materials, sliding systems, electrical equipment and other accessories is confirmed in the quotation and warranty documentation.
