Halls Silverline lean to 6x12 Toughened Glass Large Pane - Green

starting from

The Halls Silverline 6x12 lean to is a versatile lean to greenhouse, allowing you to 
customise your growing environment to suit, whether this be selecting the Forest Green colour finish to best compliment your garden or adding the various staging and shelving options 
available to maximise the growing area.


The Halls Silverline comes with a 12 year guarantee

The Halls Silverline Lean To range of greenhouses offer good value for money.

These aluminium framed greenhouses come equipped with many features which are detailed in the accordions below.

The Halls Silverline Lean to greenhouse comes with toughened glass as standard. This is far stronger glass, better able to withstand damage from children playing ball or accidents when someone falls against the glass.
Each pane is held in with spring wire ‘W’ clips.

Halls separate base

The Halls Silverline lean to requires a base and cannot be erected straight onto slabs or concrete.

A brick surround can be laid out, but a better and cheaper option is the galvanised steel base, which can be purchased in addition. This allows the lean to to be erected directly onto a soil site, the corner anchors of the base just need to be concreted into position to secure it.

If you prefer to construct a brick plinth then we can provide you with the exact outside base dimensions. The bottom cills of the lean to overlap the brickwork so it is important that the base is built exactly to these dimensions.

The Halls Silverline 6x12 lean to comes with two roof vents.

You can improve the ventilation by adding a louvre vent and an automatic roof vent opener for convenience and automatically controlled ventilation.




Halls 12 year guarantee

Every Halls greenhouse is backed by a 12 year guarantee – so you know that you are buying a product that can be enjoyed for years to come.

Q. Can this greenhouse be sited directly onto my garden?
A. Yes, provided you have ordered the optional galvanised steel base. You must secure the greenhouse by concreting in the ground anchors. 
If you are siting it on a lawn then be sure to take the top level of turf off. Cut the lawn back at least a spade width all round so that you don’t have grass growing right up to the edge of the greenhouse. You could fill this area with shingle after the greenhouse is installed.

Q. Can I lay a brick surround?
A. Yes this is possible, the brick surround would need to be built to the exact dimensions supplied in the base plan. It is recommended that solid engineering bricks are used.

Q. What about laying slabs round the perimeter for the base to sit on?
A. As this greenhouse requires a raised plinth, a flat slab perimeter would not be suitable unless you select the optional galvanised steel base plinth.

Q. Can I erect the greenhouse on a paved patio or concrete area?
A. No, this greenhouse requires a raised brick plinth. However, there is an optional galvanised steel base available which can then be fitted onto a paved or concrete area. Exact greenhouse base dimensions can be provided.

Q. How do I fix the greenhouse down?
A. Soil (with optional galvanised steel base plinth) - dig a hole at each point and concrete the ground anchors into position.

Brick surround: You will need to drill holes into your
hardstanding base and fix the greenhouse down using screws and rawl plugs.

Q. Is drainage a problem?
A. You’ll be sloshing a lot of water about inside the greenhouse all year round so it is a very good plan to allow this to drain away rather than sit in puddles inside the greenhouse. For further information please contact

Base Options

The galvanised steel base allows the greenhouse to be erected directly onto a soil site, the corner anchors of the base just need to be concreted into position to secure it.

It is available in a plain galvanised steel or powdercoated green finish.

Extra Ventilation

The right combination of roof vents and side louvres allows you to take complete control of your ventilation. Air can enter low down through side louvers, circulate up through the greenhouse, and escape out of the roof vents. Ideally fit more than one louvre to all but the smallest greenhouse.

Roof vents also work best in conjunction with automatic roof vent openers which are solar powered, very reliable and absolutely brilliant at regulating the temperature. Fit one per roof vent. It really is worthwhile ordering extra ventilation along with your greenhouse, as it’s inconvenient and much more expensive to add once the greenhouse is erected.
