Home/Products/Self build conservatory kit or have it placed?

People interested in a wrought iron garden conservatory of DBG Classics have two options to install the conservatory: self build conservatory kit on the basis of a detailed assembly plan OR have a conservatory built by a recognised installer of DBG Classics.

DBG Classics designs your glass greenhouse to size and all parts are drawn in 3D. Everything is therefore put together virtually to ensure that the construction is flawless.

Self build conservatory kit – advantages

Opting for a DIY pack from DBG Classics is possible. The greenhouse and all parts (including detailed plans) are delivered to your home. The delivery period is three to four months.

A self build conservatory kit can save construction expenses and is a challenge for experienced DIY enthusiasts.

Many (landscape) gardeners opt for this and then build the wrought iron DBG Classics conservatory together with the customer.

Self build conservatory kit – requirements

To build your own conservatory isn’t for everyone!

Experience, insight, handiness and the right tools are a necessity to bring a such a project to a favourable conclusion.

Proper preparation is half the work.

Self build conservatory kit – steps

After delivery all material needs to be unpacked.

Depending on the type of greenhouse, a foundation may or may not be required.

For instance, greenhouses placed on a medium high wall require a foundation.

DBG Classics provides the detailed plans for the foundation, brickwork, and sills.

For greenhouses with glass down to the ground (i.e. without a wall), a cap stone or copingstone is placed in stabilised sand.

Parts of the greenhouse consist of welded steel profiles that are hot-dip galvanised. This treatment is the ultimate treatment to preserve steel and to protect it against rust.

Hot-dip galvanised steel provides considerably better resistance against corrosion (rust) than traditionally painted steel. However, even hot-dip galvanised steel will corrode.

For long-term protection it is therefore finished with a rust-protective coating for hot-dip galvanised steel (before placement).

After placement of the steel profiles, the glass needs to be positioned. This is done with an overlap of +/- 3 centimetres:

Copper hooks of eight millimetres wide and 0.5 millimetres thick are used to achieve this.

After placing the glass, the greenhouse is treated with traditional methods with putty based on linseed oil. This traditional finish was common in the past for placing windows in rabbets.

The mastic DBG Classics uses is a filling paste based on synthetic resin, linseed oil and filler. The mastic is a workable paste applied with a spatula, filler knife or putty knife, partly on the edge of the glass and partly in the metal profile.

The base must be clean, dry, and dust- and grease-proof. It also needs prior treatment with primer.

To apply the mastic it must be dry and the temperature needs to be at least 15 degrees centigrade.

When the mastic has dried, two final layers can be applied in the desired colour.

The mastic can be painted over after several weeks (between three and eight weeks after application). The optimum conditions for this are a temperature of 23 degrees centigrade and relative humidity of 55%.

Putty is oxidative drying which means that this paint dries through oxygen intake. This is why putty must always be painted over after the hardening phase.

By systematically going over these steps, you create an authentic greenhouse that is equally magical as it is impressive:

One can also opt for a hybrid kit, i.e. putty that remains elastic, developed as a substitute for classic mastic based on linseed oil.

Self build conservatory kit – tips

  • Try to orient your greenhouse the right way. Optimum orientation is southwest with the facade of the greenhouse facing south. By aiming the long side of the greenhouse (= largest glass surface) east and west, the greenhouse will warm up and cool off evenly.
  • Try to make the greenhouse easily accessible from your house. This will ensure that your wonderful garden greenhouse will be used more often.
  • Think about a sprinkling or watering system. By digging a simple tube into the ground or hanging it from the roof ridge of the greenhouse with a few holes in it, you can easily make a basic sprinkling system. Simply connect the garden hose and your plants will have enough to drink!
