What is the Cost of an Aluminium Sunroom Extension Vs. uPVC Sunroom Extension?

When it comes to selecting the material for your sunroom extension there are a few options available. Aluminium and uPVC are the most common due to the modern functionality they bring and the increased thermal efficiency that they provide. There are similarities and differences between the two, both with unique advantages that you may want to consider.

uPVC is an affordable solution for your sunroom extension offering a highly weatherproof option that will keep your home warm and dry all year round. uPVC comes in a range of different colour options and finishes giving you the ability to seamlessly blend your sunroom extension with the rest of your home or select a colour to make it stand out.

Aluminium is a premium quality material that is incredibly robust and strong. Although it excels in strength it is also very lightweight making it a flexible and versatile material that is popular due to the ability to use less frame and more glazing areas. This results in slim sightlines and unobstructed views.

Between the two, aluminium is slightly more expensive and choosing the material will depend on your budget and preferred sunroom extension design. Both materials are highly sought after and provide high performance and superb results for any property.

This will largely depend on your location. You will find that certain areas have different setbacks based on the use of the building. We recommend that you check with your local council or take a look at the Goverment's Planning Portal.

You must notify your neighbour if you want to:

- Build on or at the boundary of your 2 properties - Work on an existing party wall or party structure - Dig below and near to the foundation level of their property
Replacing your conservatory roof can indeed make your conservatory warmer however, this will depend on the type of roof you choose. A solid or tiled conservatory roof will offer greater insulation than a plastic or glazed roof.
A solid roof can be put on a conservatory. There are many solid conservatory roof designs available - just ask your chosen installer for a recommendation.

Solid ground will need to found first and needs to be accepted by Building Control as being a minimum of 1 metre in standard conditions.
Foundations will need to be dug and because conservatories are lightweight in structure, their foundation loads are usually quite low. This can often lead to the notion that shallow foundations are satisfactory however, shallow foundations are more susceptible to subsidence.

Conservatories that are built with foundations shallower than the Building Regulations advise, are likely to encounter problems.

Building Regulations state:

A2. The building shall be constructed so that ground movement caused by :-
(a) swelling, shrinkage or freezing of the subsoil; or
(b) land-slip or subsidence (other than subsidence arising from shrinkage), in so far as the risk can be reasonably foreseen, will not impair the stability of any part of the building

Any structure that is built as an extra living quarter will require its own council tax band, even if it shares facilities with the main dwelling.

On average, an orangery can cost anything from £10,000 to £20,000. It is likely to cost double the amount of a conservatory, however it's important to note that an orangery provides more functionality and home value when compared to standard glazed conservatory.
An orangery allows you to benefit from both conservatory and extension, being a combination of the two.

An extension refers to an additional structure that is anatomically in-keeping with your main property. An extension often requires planning permission unless it is classified as permitted development and is built with opaque cavity walls and brick-based foundations. Extensions are a big home improvement and investment, needing the work of an architect.
Conservatories or glazed extensions are perfect for those looking to add extra space on a budget. Typically, they are less of a logistical strain and in most cases do not require planning permission,
A conservatory can be built under permitted development rights, not needing an application for planning permission. A conservatory however is subject to the limits and conditions listed here. Building a conservatory onto an extension however, will be subject to different conditions.
