FREQUENTLY ASKED QUESTIONS

We know that you may have living space questions for us and we’ve answered a few that we regularly get asked here.
What's the difference between a conservatory, orangery and an extension?

This is a very popular question and in all honesty, they can all be considered as living spaces due to how blurred the lines are between them nowadays. In the past, a conservatory would predominantly consist of glass, present in the roof and walls, giving you fabulous garden and aerial views. Fast-forward to now and you will notice that many conservatories have tiled roofing systems, which do a good job of providing insulation and internal warmth. To prevent overheating in a conservatory, you can always rely on solar control glazing.

An orangery is characterised by either brick or aluminium pillars, affording you the utmost in privacy and warmth, and offering a luxurious living destination. There’s also usually a pelmet around the roof’s perimeter which makes a big contribution to the thermal insulation the space offers. As for its roof, anything goes. You can have a glass lantern, solid tiled roof or crossover between the two.

If you want something that feels like a natural extension of your house, a home extension is probably the best option. A home extension has a very solid feel, plenty of brickwork and typically features a solid tiled roof. But you can have a hybrid roof, one that incorporates glass panels and / or Velux windows, great for bringing in light and ventilation. The useability of a home extension is a big selling-point as it delivers exceptional temperature control in all weathers.

At the end of the day, they’re all outstanding living spaces. Talk to an advisor to find out more about them all.

Do I opt for a tiled roof or a glass roof?

This decision all comes down to a series of factors, such as how you intend to use the space, which direction it needs to face, and how much money you have to spend. If you’re looking to have a bright-filled space, with a captivating garden view, the inclusion of solar control glazing will ensure that your tiled or glass roof doesn’t cause the space to overheat.

We highly recommend a solid tiled roof if you want an extension that you can use year-round, and complement it with full length glass panels or Velux windows. That’s when it becomes a hybrid roof, giving you a combination of the benefits of a solid and glass roof.

For a discussion about tiled and glass roofs, just reach out to a Mitchell Glass advisor.

MORE COMMON QUESTIONS

You can direct any questions that you have to an advisor. However, you may find an answer to your questions below, some of the questions we’re most commonly asked.

Will it be too hot in summer and too cool in winter?

We know that this is a major concern for many customers, so that’s why we prioritise year-round comfort when designing all of our living spaces. The old polycarbonate roofs, that used to turn conservatories into red-hot greenhouses, are long gone. Using solar control glazing eliminates any possibility of excess heat internally, but if you want to be doubly sure of a year-round extension, we suggest that you include a tiled roof in the design to fight off the weather.

Do you manufacture your own roofs?

We certainly do. Mitchell Glass is very proud to be a member of the Conservatory Outlet Group of companies, and Conservatory Outlet is a highly-respected manufacturing of roofing products. They manufacture them at their state-of-the-art manufacturing facility in Wakefield, West Yorkshire.

The tight bond we have with Conservatory Outlet helps us to retain close control over our supply chain, so we know that roof manufacturing standards are always consistently high.

Can I choose different roof tiles to match my home?

Of course you can. You’re able to select from a range of shingle and slate roof tiles, and you won’t have any issue finding a tiled solution that matches the roof tiles on your house. A number of flat roof membranes are also available. To discuss roof tiles in more detail, speak to a Mitchell Glass advisor.

I’ve heard about energy rated windows. What are ‘A’ rated windows?

As per the BFRC Rating Scheme, A rated windows are the most energy efficient windows you can get in the UK. All windows sold in the UK are labelled with an energy efficiency rating so that you can identify their thermal performance and also check whether the thermal efficiency they offer complies with current Building Regulations.

A bit like you find on ‘white’ goods e.g. fridges, freezers, washing machines, a traffic-light style energy rating system is used on windows, with them rated from A-E. Please, always look out for the energy rating of any set of windows to help you make a more informed buying decision.

What is solar control glazing?

There is an inventive coating on solar control glazing that helps prevent excessive heat from entering into a room and also stops internal heat from escaping. You can request tinted glass if you want to determine the level of light transmission and heat retention, and there are a series of tints available. Just talk to one of our advisors for guidance on solar control glazing.

Can I brick match my existing bricks?

We will make a concerted effort to find the closest possible brick match to help your living space match up nicely with your home. Please, be advised that there can be weathering and manufacturing differences between existing and new bricks. If we experience difficulty locating a suitable brick match, it can be tinted to solve that, but this will require an additional cost.

Will I need Building Regulations Approval?

To extend a property you generally need to obtain Building Regulations Approval, but there are certain classes of extensions that don’t require it. Mitchell Glass will clarify this. One of our surveyors will guide you through and inform you of the process, making it as stress-free as they possibly can. If Building Regulations is necessary, Mitchell Glass will approach your local authority to get this organised.

Will I need planning permission?

It all depends on whether the proposed extension satisfies the criteria to be considered a permitted development. A permitted development does not require an application for planning permission to be submitted, so long as these conditions are met:

  • The ground area covered by the extension and any other buildings within the boundary of the property, excluding the original house, is not more than half the total area of the property.
  • Any part of the extension is not higher than the highest part of the roof of the existing house.
  • The eaves of the extension are not higher than the eaves of the existing house.
  • Any part of the extension does not extend beyond any wall facing a road if it forms the principal or side elevation of the original house.
  • The eaves are no more than 3 metres in height if any part of the extension is within 2 metres of the property boundary.
  • The materials used in exterior work, except in the case of a conservatory, are of similar appearance to the existing house.
  • An upper floor window on a side elevation within 15 metres of a boundary with another house is obscure glazed; and is non – opening unless the parts which can be opened are more than 1.7 metres above the floor of the room in which the window is installed.
  • A side extension does not exceed 4 metres in height or be wider than half the width of the original house.
  • In a single storey extension
    • the extension does not extend beyond the rear wall of the original house by more than 4 metres for a detached house or 3 metres for any other type of house;
    • the height of the extension does not exceed 4 metres;
    • no part of the extension is within 3.5 metres of any property boundary with a road opposite the rear wall of the house.
  • In an extension with more than one storey
    • the extension does not extend beyond the rear wall of the original house by more than 3 metres;
    • no part of the extension is within 7 metres of the property boundary opposite the rear wall of the house;
    • the roof pitch of the enlargement is as far as practicable the same as that of the original house.
  • If you live in a house within a conservation area, World Heritage Site, area of outstanding natural beauty or National Park-
    • no part of the exterior of the house is clad with stone, artificial stone, pebbledash, render, timber, plastic or tiles;
    • the extension is not more than 1 storey or 4 metres in height;
    • no part of the extension extends beyond a principal or side elevation of the original house

What is the timescale for building my new living space?

It is hard to give you an exact estimate of how long it will take as it all depends on whether there are any planning requirements and how complex the project is. Ask for a copy of our ‘What happens next’ guide to gain an understanding of the building process.

What is a test dig?

We carry out a test dig to check that the ground is sufficient for a traditional concrete base and foundation, prior to performing any construction work. Upon the discovery of the ground being suitable, we will inform you of an alternative foundation proposal such as a specialist pile foundation or concrete raft.

Can you tell me what a cavity tray is?

A cavity tray is a series of high level damp proof courses that bridge a wall cavity to direct moisture to the external face of a wall where the extension roof joins the house wall. To put it more simply, it counteracts any moisture forming on the outer wall and becoming visible in the extension.

Do you offer finance to help me pay for for my new living space?

Yes. To make life easy for you, Mitchell Glass can arrange a variety of affordable and convenient easy payment finance options (subject to application & status). Applying for finance is simple and we promise you a quick decision. Everything can be sorted out with you in the comfort of your home or at your local Mitchell Glass Showroom, so you can enjoy whatever you’ve set your heart on right away.

What do we need to do when our finance is approved?

If you’re arranging your own finance, you’ll need to call us as soon as you get the go ahead. If you’re taking up one of our offers, the company will tell us both directly, so there’s no need to call as we will get in touch with you.

What happens if finance is refused?

Finance companies can turn down people for lots of reasons, for example if you’ve moved several times over the past few years. In these circumstances, we always do our best to help and sometimes it’s worth trying another provider, especially if they know you.

I’ve applied for finance with Mitchell Glass. How long will approval take?

Sometimes our finance company will say ‘yes’ almost immediately and on other occasions it may take them a few days. This short delay can be for any number of reasons and you should not be unduly concerned.
