Glazed Extension Styles

You are here: Home / Glazed Extension Styles

Whether you intend to open up the space to your existing property or design it as a closed off space for occasional use.  All of these factors will be discussed with you by your CIN installer.  And only after careful consideration will you finally sign off your design.

Some key design styles and how they work:



Conservatory – things have really moved on in the world of conservatory design.  Not only are today’s conservatories able to deliver far superior thermal performance but there’s also the opportunity to build in extra features that will give the space greater thermal performance and greater solidity.  Often you can now build in a internal pelmet system that will allow you to integrate lighting and cabling for speakers.

Perfect for: either occasional use or a space that doesn’t need to be open to the rest of your property.  Allows you to create a space that brings your garden into your home.



Loggia (the modern orangery) – Loggia take the conservatory to a whole new level of thermal performance and with the addition of super-thermal columns – the more you add – the warmer the space.  Combined with an internal pelmet system and external cornice, a Loggia starts to feel like a traditional extension to your home.

Perfect for: every day use where you’d like to remove the external wall and create an open plan living environment.  Loggia columns not only provide significant thermal performance but they also give you the chance to ‘bespoke’ your extension with the use of colour.

 Solid roof extensions

Solid roof extensions – you don’t need a builder to construct a traditional solid roof extension you can use all the advantages of a CIN installer to create a fully-loaded home extension.  Our CIN installers will use two different roof systems depending on the look that you are trying to achieve.  There are no limits to the type of roof that can be used – they can even design a roof that will use the same tiles as on your property if that’s the look you want.  Both roof systems deliver the ultimate in thermal performance and both deliver a beautiful vaulted roof space with the option of integrating glazing to flood your space with natural daylight.

 Conservatory transformations

Conservatory transformations – if you’ve had a conservatory ten years or more (or less depending on the quality of the original build) then you might consider transforming your conservatory.  As long as you’re happy with the footprint of the original design then a CIN installer can replace your roof with a solid option.  They’ll need to check your side frames are still in great condition but they’ll give you that advice.

Reasons to appoint a CIN Installer

A CIN installer will give you a fixed price for your installation and build which will include everything you’ve asked – some CIN installers will even carry out your final electrical works, flooring and even redecoration. Whatever agreement you come to be rest assured that your CIN installer won’t surprise you at the end with an unexpected bill.

Small buildings works can be a headache if you plan your life around a certain start date and it keeps slipping back. Nobody wants their home extension to slip back – your CIN installer will give you an accurate start date at the point that you agree to engage their services.

All too often we hear about building jobs that either drag on or never get completed – that won’t happen with your CIN installer.

Communicating with you about your build is an essential component of the CIN Charter – you’ll always be able to talk to a project manager and have a clear work schedule presented at the start of your project.

If you are considering a highly glazed home extension such as a conservatory, Loggia or orangery it’s essential that your new space incorporates the very latest glass technology to ensure your home is thermally efficient – your CIN installer will be fully up to speed about the latest technologies for glazed extensions.

A CIN installer will always clearly introduce and communicate who the trades people are in your property. It’s not often practical for you to be at home the entire time you are having work completed so it’s essential that you feel safe and confident that only trusted and reliable tradesmen are in your home – a CIN installer will give you that peace of mind.

We only invite the very finest installation companies to join our CIN installer network after a thorough vetting process. Every CIN installer will construct your extension to the appropriate building regulations standard; if planning permission is required they’ll even sort that out for you in most cases.

As a general rule planning permission is not required for a conservatory, although there are a few exceptions to this rule, and they are:

  • no more than half the area of land around your property would be covered by additions or other buildings. This calculation is based on your original property.  So if you have already have an existing extension you’ll need to take that into consideration.
  • Your conservatory, or extension, cannot extend forward of your existing property – both at the front or the side.
  • If you are having an extension, it can’t be higher than your existing roof.
  • The maximum height of a conservatory or single storey extension is four metres.
  • For further information on planning permission visit

Every installation is different, while you might not need Planning Permission, you might need Building Regulations.  While Planning Permission governs the look and aesthetic impact of your property, Building Regulations are in place to check that the work being carried out is safe and energy efficient but it also includes structural and electrical safety, effective ventilation and drainage to name but a few.

Some conservatory designs are exempt from Building Regulations but if you’re planning to remove an exterior wall and make the plan ‘open space’ then you’ll need Building Regulations consent.  If however, you’re planning to keep the new space separate from the existing house, you’re planning to use a separate heating source then Building Regulations will not be required.

If your new doors and windows are similar to the ones you are replacing then you won’t need Planning Permission – but if you’re having a new bay built, you might need Planning Permission for that, you’ll need to check with your local Planning office.  New windows and doors are, however, governed by Building Regulations which ensure that your replacement windows and doors are safe, provide sufficient air supply, appropriate means of escape and ventilation.

A CIN installer will be approved to carry out the work to comply with building regulations without involving your local authority building control – once the work is completed they will send you a certificate showing the work has been done by a registered installer.
