Conservatories, Orangeries & Glazed Extensions

A conservatory is a fabulous addition to any home. At Stormclad we have designed and installed thousands of conservatories over the years in a huge variety of styles and sizes.

Whatever footprint you have available we will be able to design for you a conservatory that fits your exact requirements. What’s more we take all the hassle out by providing you with a complete one stop service that looks after everything from initial design through to final installation.

Our team of planning experts will be able to advise you on whether you need to apply for planning permission or require building regulations approval from your local authority. For an overview on when this is necessary please refer to our Frequently Asked Questions section. As an alternative to a conservatory we are also able to offer you an exquisite range of orangeries and glazed extensions. These beautiful buildings bring a new dimension to any property.

We always strive to give you as much information as possible to help you make your Home Improvements choice. The following are the questions that we get most frequently asked. If there’s anything else you’d like to know please get in touch

Show FAQs

Can I use my new conservatory straight away?

Yes of course. As part of the great Stormclad service we can offer you a complete package that includes decoration and a selection of flooring including laminate, ceramic tiles and carpeting. We can also supply heaters, underfloor heating and air conditioning.

Your Designer will be able to go advise you on the host of options that will enable you to start enjoying your new conservatory straight away.

Can I use my conservatory all year round whatever the weather?

Stormclad conservatories can be used all year round because they have insulated bases and cavity walls, and feature thermally efficient double-glazed units and roof glass. Like your home, on the coldest of days, the sensible use of heating will also help. The technology built into our glass helps to reflect the sun’s heat in the summer too, keeping your conservatory comfortable all year round.

Do we need Planning Permission or Building Regulation Approvals?

Planning Permission

At Stormclad, our full design and technical survey procedures mean that the whole build process is managed for you, including Planning Permissions and Building Regulations, so you needn’t worry about this.

However, under regulations that came into effect from 1 October 2008 adding a conservatory to your home is considered to be permitted development, deemed as exempt from planning permission, subject to the following limits and conditions:

  • No more than half the area of land around the “original house”* would be covered by additions or other buildings.
  • No extension forward of the principal elevation or side elevation fronting a highway.
  • No extension to be higher than the highest part of the roof.
  • Maximum projection of a single-storey rear extension of 3 metres for an attached house and 4 metres for a detached house.
  • Maximum height of a single-storey rear extension of 4 metres.
  • Maximum depth of a rear extension of more than one storey of 3 metres including ground floor.
  • Maximum eaves height of an extension within 2 metres of the boundary of three metres.
  • Maximum eaves and ridge height of extension no higher than existing house.
  • Side extensions to be single storey with maximum height of 4 metres and width no more than half that of the original house.
  • Roof pitch of extensions higher than one storey to match existing house.
  • No verandas, balconies or raised platforms.
  • On designated land* no permitted development for rear extensions of more than one storey; no cladding of the exterior; no side extensions.

Where work is proposed to a listed building, listed building consent may be required.

* The term “original house” means the house as it was first built or as it stood on 1 July 1948 (if it was built before that date). Although you may not have built an extension to the house, a previous owner may have done so.

*Designated land includes national parks and the Broads, Areas of Outstanding Natural Beauty, conservation areas and World Heritage Sites.

Building Regulations

Building regulations will generally apply if you want to build an extension to your home. However, conservatories are normally exempt when they meet a number of conditions:

  • They are built at ground level and are less than 30 square metres in floor area.
  • At least half of the new wall and three quarters of the roof is either glazed or translucent material.
  • The conservatory is separated from the house by external quality door(s).
  • Glazing and any fixed electrical installations comply with the applicable building regulations requirements.

You are advised not to construct conservatories where they will restrict ladder access to windows serving rooms in roof or loft conversions, particularly if any of the windows are intended to help escape or rescue if there is a fire.

Any new structural opening between the conservatory and the existing house will require building regulations approval, even if the conservatory itself is an exempt structure.

Please note that requirements in Scotland, and to a lesser extent, Northern Ireland are different to those in England and Wales.

On April 1st 2002, the Government introduced Part L, amending the Building Regulations for the first time, to require replacement windows and doors to meet tough new thermal performance standards. The new standard applies when new doors replace an existing window or you change the doors between the house and the conservatory, but not when you keep the existing lockable French doors or patio doors between house and conservatory.

Do you make conservatories to order?

At Stormclad all of our conservatories are manufactured to your individual requirements. They can be personalised with a range of design features and we also have a selection of accessories for you to choose from.

We’ve got an odd shaped space – will it still be possible to have a conservatory?

Because of all conservatories are made to your specific requirements, we can design anything that’s physically possible for you.
