4ft wide lean to greenhouse

Full specification

The Dovetail 4ft wide lean to greenhouse

Our lean to greenhouse range is practical and versatile. The 4ft wide lean-to can be manufactured by Dovetail either as a glass-to-ground structure, or built onto a dwarf wall, even when space is at a premium.

The standard Dovetail Senator Lean-to has the option of a double door dependent on length, with generous head-room when working, and with an eave height of 6ft 2in. Reduced height options are also possible. We can adjust the height or length of any greenhouse – all you have to do is ask.


Our standard method of retaining horticultural glass uses a wide, stainless steel clipping system. The clip is so designed to equalise the pressure between the glazing face and the frame of the greenhouse. When single sheet toughened glass is ordered with this type of building, we can also offer our unique aluminium capping system rather than clips that gives an attractive clear line to the glazing. Types of glazing available are:
3mm Horticultural glass, 4mm Toughened safety glass and 6mm twin walled Polycarbonate galzing.


When fitting a lean to greenhouse onto an adjoining wall there a few things that need to be taken into account. The base, which can be as simple as a row of slabs, must be level, and at a true 90 degrees to a vertical rear wall. The smoother the adjoining wall the better, as this will make the sealing of the greenhouse easier when the construction is completed.

Noteworthy features

All of our greenhouses can be altered to suit your individual needs in width, length and height. Built-in aluminium gutters are supplied. If required, our lean-to greenhouses can be designed to fit onto a dwarf wall. All of our greenhouses can be powder coated. Standard colours are white, green and brown. Other colours are available.
