Conservatories and Garden Rooms Online - Free Guide to Conservatory Base and Dwarf Wall Construction

click here for your free brochureWhat is the specification for the base? How do I put the conservatory together? Can you give my builder a guide? 

This guide will answer many of your questions - maybe all of them! However, if there are still any questions or queries you are unsure of please contact us

Firstly, however, please note our DISCLAIMER below:

DISCLAIMER: Our construction guide is not a complete instruction manual. Feel free to download this information in our download area here but please note we cannot accept responsibility for erroneous constructions based on this guide.

To assist you with navigation we have split this guide into several pages. On this page we introduce you to some of the most common styles/types of base and dwarf wall construction. 

In the following pages we will introduce you to the "Step by Step Construction Guide"


Note - these sectional drawings are just typical sections - you or your builder/conservatory supplier may use different sections depending on site circumstances.

Example 1 (Click on examples for a larger view)
Dwarf Wall Detail

With example 1 we have a fairly typical section for the construction of a base and dwarf wall. This assumes that the site is reasonably level and without any major difficulties. As an example of a variation on the above - note that many suppliers prefer to "sit" the inside of the conservatory frame flush with the inside of the external course of brickwork. In our example the frame has been fitted slightly forward of the inside edge of the external course of brickwork in order to facilitate an easier fixing for the internal window board. Either method is OK in our opinion.

Example 2 (Click on examples for a larger view)

Typical Solid Detail

click here for your free brochure We again have a fairly typical example based on a site without many difficulties. As previous you may find that your supplier will fit the frame flush with the inside edge of the foundation. Also your builder may create a brick faced base rather than concrete faced base. In our example the conservatory frame rests on top of a damp proof membrane. This is often used when using timber frames. However with PVCu frames it is more likely your builder will lay the PVCu frames directly down on foundation. (PVCu is after all a damp proof material). The usual finish then is to "lap" the membrane that's under the concrete floor up against the frame on the inside.

Example 3 (Click on examples for a larger view)
Suspended Floor Detail

This shows a suspended floor detail often used where there is a significant difference in levels between the ground level and the finished floor level (FFL) of the conservatory. Note an air brick should be inserted at front.

Example 4 (Click on examples for a larger view)
Suspended Timber Floor Detail

We have a good example of one way to overcome a large variation between levels. You should remember with examples like this to allow for brick steps (plus other landscaping) in order to safely "step down" from your conservatory to the ground level.
