A small number of American conservatory manufacturers produce very fine work for some of the most exclusive homes in the United States. However, the vast majority of our conservatory additions were designed for more modest homes, very much built to a budget.

Our project gallery illustrates quite a broad range and style of addition, but always the starting point is the existing structure and any features which might limit a proposed addition. Also included are examples of sunrooms and  modern additions with solid roof construction. In our view the most important consideration will always be what is the new space to be used for, because an all glass structure creates a very different ambience to an "ordinary" room and there are important practicalities to consider.

A glass structure in summer can become very hot and will need appropriate screening and air conditioning; conversely on sunny winter days a glass structure benefits from solar gain and achieves comfortable temperatures without heating. Glass structures are much darker at night because light is not reflected back from the glazed walls and roof unless blinds are installed.

For the US market, our designs require an Engineer’s stamp and the vast majority of examples on this site were submitted for appraisal by a structural engineer.

A conservatory is a complex structure designed to complement the building to which it is attached, but also designed to withstand the climatiforces dependent on its location. Wind, snow loading or coastal environments all have a significant impact on the building design and materials used in its construction. Conservatories must have proper foundations, whilst they are not (relatively speaking) very heavy structures, on occasions they do require specialized foundations depending on soil conditions. Proper estimates for this element of construction can only be given following a proper site survey.The main structure of the examples shown on this page were mostly manuf actured in iroko or Western red cedar. However, there are quite a number of wood species that can successfully be used in conservatory manufacture from reputable and ethical suppliers of rough sawn lumber. We have manufactured conservatories in African mahogany, idigbo, tatajubia, sapele, Southern yellow pine. Douglas Fir and oak. Most conservatories are internally braced with metal tie bars and of course are generally physically attached to a main building. Traditionally lead flashings are used on the interface of the conservatory roof to the parent building. Generally speaking the roof units are carried on a powder coated aluminum dry glazing system which is screwed to the timber structure below. The system incorporates neoprene glazing gaskets, an internal gutter channel so that any water which penetrates a defective gasket cannot leak into the conservatory, a screw on pressure and a snap on cover so there are no visible fixings on the roof units. Apart from cleaning the roof, no other maintenance is required on the roof structure. Opening roof lights can be supplied in powder coated aluminum operated via manual screw jack or electrically with chain motors. Rain and temperature sensors can be supplied to automatically open and close roof vents.
