Hangars, greenhouses and barns

This category groups different cases in which entire buildings are reused. It concerns more specifically professional horticultural greenhouses (of which the supply is abundant in the Netherlands), industrial hangars and complete wooden sheds (quite frequent in France, among others).

In the Netherlands, it is common for old greenhouses to be completely dismantled and offered for sale by companies specialising in the dismantling and renovation of these structures. The greenhouses are mainly from garden and agricultural companies. Some traders focus on B2B sales, while others also target individuals. Greenhouse construction is largely standardised. Some dealers thus offer the dismantled greenhouses as a whole, while others treat the structure as a construction kit, and organise their stock by component. Customers can thus put together a new greenhouse themselves based on the available parts. In both cases, new parts are ordered as necessary. The original glass is often replaced for new in reclaimed greenhouses.

The market for reclaimed hangars is quite similar to that for greenhouses. Original structures, however, are more diversified and therefore hangars are more often stored and sold as a whole.

The same generally applies to sheds.

Common products

  • Greenhouses: these are professional products and the size can vary greatly. The usual surfaces of the dismantled greenhouses are between 1000 m² and 15,000 m². But, as described above, some dealers offer to put together a new structure based on the available parts. Some dealers also sell smaller kits to individuals, starting from around 10 m² of ground surface.

  • Greenhouse materials such as installations for ventilation and heating, assimilation lamps, mist installations...

  • All kinds of sheds and hangars. Often only the structure is reused, completed with new insulation, wall and roof panels, but it is not uncommon to reuse these as well.

  • Old hangars with welded joints can also be reclaimed, but this is done less due to the high cost of the operation.

  • Canopies with a supporting structure made of glued-laminated timber beams ('glulam').

  • Old barns in solid oak. 

  • ...

Recorded prices

  • Greenhouse: around 60% of the new price, including installation.
    Example: Greenhouse of 4 × 6m: total price of 1,000 € including VAT, including glass and door, without installation.

  • Hangars and sheds: around 60% of the new price.

Available services

What follows mostly apply to hangars and sheds:

  • All parts are checked and where necessary repaired or replaced. Some dealers are in contact with the manufacturers of new structures for this purpose.
  • Rust stains and other minor damages are eliminated.
  • It is sometimes possible to repaint the structure, but it is rarely necessary.  

The assembly of the entire structure is usually carried out by the dealers themselves, since they have the necessary knowledge and resources. This is often included in the price for larger structures.

Did you know

In the Westland area, located between The Hague and the Oranjekanaal, Netherlands, there are a dozen dealers specialised in salvaged horticultural greenhouses. With 2,300 ha of glazed surface, accounting for 40% of the entire region, Westland has the highest concentration of greenhouse horticulture in the world. The first greenhouses were already built as of 1850. The entire area, which lights up orange at night, is also known as 'The Glass City'. Virtually all greenhouse builders and installers sell both new and reclaimed greenhouses there.
