Conservatory Versus Extension discussed by Guardian Roofs UK

If you are thinking about extending your home and you have the space to do it there is a lot to think about. Our article talks about Conservatory V’s Extension to help you with your decision so you can start planning your new space in your home.

SIP ExtensionWhen you start to think about extending your home remember that conservatories have changed a huge amount in the last few years so don’t think about them as the older style ones with polycarbonate or glass roofs which are too hot in the summer and too cold in the winter which looks like they have been bolted onto the back of your home.

New style conservatories can now look and feel like a ground floor extension, with solid tiled roofs which regulate the temperature all year round, matching brickwork, plastered finishes inside and heating which means you can use them all year round.

Considerations when thinking about extending your home – Conservatory Versus Extension

  1. Plan how you will use your new extension or conservatory. Many people extend their homes without thinking about how they will use the new space and how it will work in conjunction with the rest of their home, and people often wish they had extended differently as the additional space isn’t used as much and effectively as it could have been. Planning your extension with a defined use in mind means you will get the most out of your additional space and the money you have invested
  2. An extension can be a first and second-floor extension, building up into your loft to make the most of your existing home or adding a new style conservatory. Always think about extending your home as a blank canvass, what you will use the space for, who will use it and when. When you are deciding, think about how you could change the use of existing rooms in your home so you can achieve the layout you are looking for. Look at different styled roofs, the shape of your extension and internal and external doors which will open up your space in your home and into your garden
  3. Where you add your extension is a really important factor to ensure it fits with your home internally and its external surroundings. You don’t always have a huge amount of options due to access and outside space so plan the design of your new extension or conservatory to complement, or even contrast your home and its surroundings.
  4. The construction materials used when extending your home are really important and include; brick style and colour, roof tiles, render, cladding and material type. They are essential to ensure you get the finished look you want. Look for ideas on the internet for both the exterior and interior of your extension or conservatory so you get new ideas that you may not have thought about before
  5. Always set yourself a budget before you start planning to extend your home. Extending or adding a conservatory is often a cheaper and more cost-effective way of increasing your living space compared to moving and moving costs, however, it’s crucial to budget not only for your build but for your fixtures, fittings and finishes too as a lot of people will overspend on these aspects. You should also include architect and planning costs if you are adding an extension rather than a conservatory as these are normally more than you think they will be
  6. Talk to your neighbours when you are deciding if you want to add an extension or conservatory. Talking to them and getting them on your side is important if you need to submit planning permission and it will give you the confidence that they won’t raise any objections which can make your planning application more difficult. A quick conversation with them to talk about what you are planning, the design and why you want to extend will get them involved and help them understand your proposal so they won’t object. Ask them if they are unsure about anything or if they have any objections
  7. Think about your outdoor space and how you will use it when your extension or conservatory is finished, do you want bi-folding doors which open up into the garden and a revamped and spruced up garden with clean patio slabs and garden pots to add a bit of colour as this will give you the perfect finish you are trying to achieve
  8. Choosing the right company to help you plan and construct your extension or conservatory is critical to meeting and not exceeding your budget. A traditional extension will cost more than a Guardian SIP Extension and won’t look any different so always look into the different types of extensions. A Guardian SIP extension is designed to your specification, it is 50% quicker to construct, with an average of 30% reduction in labour costs, less mess and waste, they are highly energy-efficient and have beautiful finish options inside and out to compliment your home. A good, reputable and professional extension company will work with you from start to finish to give you a beautiful home extension, helping you with the minefield of permitted development, planning permission and building regulations so you don’t need to worry
  9. Choosing the right Conservatory Company is also essential if you decide this is the option for you. Again they will help with all aspects of you planning your design internally and externally and will often give you ideas you won’t ever have thought about before.

Conservatory Versus Extension – What are the benefits of a conservatory with a Guardian™ Warm Roof?

Conservatories have developed significantly over the last 10-years and there are so many more styles and variables available now which offer many benefits. A conservatory gives you an additional room or rooms in your home and new style conservatories with solid tiled roofs give you an additional modern and contemporary space that connects your home seamlessly to your garden.

Guardian Solid Warm RoofIf your conservatory is over 15 years old then it is likely it will have an older style polycarbonate or glass roof which will now need replacing and doing this will transform your old conservatory which gets too hot in the summer and too cold in the winter into a new and usable room again. Guardian™ Warm Roofs are extremely lightweight and this means they can normally replace an older style roof without any structural changes to your conservatory. Most people really want to love their conservatory, however, it’s either too hot, too cold or too noisy and most of these issues are because of the polycarbonate or glass roof. If you replace your conservatory roof with a new and stylish Guardian™ Warm Tiled Roof, you don’t just improve its appearance but you will have a fully insulated and soundproof roof that makes your conservatory usable again. It will be bright, modern and airy inside and substantial and impressive on the outside, making it look like an extension rather than a bolted-on old conservatory.


Solid tiled conservatory roofs are becoming more and more popular when it comes to new and old conservatories so if you are thinking about adding a new conservatory or replacing your existing conservatory roof then a Guardian™ Warm Tiled Roof will create an additional room in your home and make it look and feel like a traditional extension internally and externally.

Design & Finish

Solid conservatory roofs now come in a huge range of styles and colours and Guardian™ Warm Roofs are manufactured to your specific conservatory design whether it is a new extension or you are replacing your old conservatory roof. You can choose to match the tiles to your home or you can go for something completely different as a contrast. Whichever option you choose it will transform your home or existing conservatory internally and externally.

A professional conservatory company like Guardian Roofs UK will come out to your home and help you with the design of your new conservatory, or they will assess your existing conservatory structure to ensure it is sound enough for a new replacement roof. They will take all of the necessary measurements and support you with everything from planning and design, right through to your installation and internal and external finishes. We offer a solid roof solution for virtually any shape or size conservatory so don’t worry if your conservatory isn’t a typical style or shape as we offer a fully bespoke replacement roof service which is manufactured to your exact measurements.

The Guardian™ Warm Roof has a huge range of roof tiles to choose from to best match your existing home. So whether you are replacing your conservatory roof or building a brand new one you can choose the best style and colour for your home. You can choose from a modern plastered finish inside or if your room is naturally bright a timber finish may a better option for you. You can enhance the light entering your conservatory by adding a skylight or two and add some contemporary spotlights to bring the room to life in the darker evenings.


Tiled conservatory roofs are extremely thermally efficient and enable you to use your space in the summer and winter, unlike a glass or polycarbonate roof which make it too hot in the summer and too cold in the winter. The Guardian™ Warm Roofs structure, tiles and insulation make its thermal efficiency (energy rating A) which will reduce your heating bills and keep its temperature regulated and comfortable all year round, making it the perfect conservatory roof replacement or ideal for a new conservatory. It has been independently proven that a Guardian Warm Roof can save you money on your energy bills as the high-performance insulation and layers achieve a superior U-value of only 0.18 W/m.K (England & Wales) and 0.15 W/m.K (Scotland).

Cleaning & Maintenance

A solid tiled conservatory roof needs minimal cleaning and maintenance if any at all, comparing this to a polycarbonate or glass conservatory roof which are really difficult to keep clean, smudge and watermark-free at any time of the year. Most people who have a glass or polycarbonate roof are frustrated with the smears and smudges that are there whether it’s just been cleaned or not and need to have a professional window cleaner who can reach right up onto the roof safely to come out to clean it.


Solid conservatory roofs are extremely durable and hard-wearing similar to the tiled roof on your existing property. Most manufacturers and suppliers of solid tiled conservatory roofs offer 10 year plus guarantees after installation and in truth, they will last much longer than this. A new Guardian™ Warm Roof will provide additional strength and support to the structure of your existing conservatory if you replace your old-style polycarbonate or glass roof.

Versatility & Cost

A Guardian™ Warm Roof can easily replace a glass or polycarbonate roof and this means you don’t have to start all over again and have a whole new conservatory built, saving you time, mess and money. As long as your conservatory structure is sound then Guardian Roofs UK can easily and quickly replace it. If you are having a new conservatory built then having a Guardian™ Warm Roof will ensure it lasts a lifetime and gives you a new room in your home that you can comfortably use all year round.

What is SIP Extension with a Guardian™ Warm Roof?

SIP Extensions are an extension to your property using prefabricated structural insulated panels which are manufactured to your specific design and measurements off-site and delivered to your home in large modular enabling it to be built quickly and easily with minimal mess and construction time. The SIP panels consist of an insulating polystyrene core which is sandwiched between two structural facings and they are now used a lot as an alternative to more conventional brick, blocks, or timber frames.

SIP Panel ExtensionsSIP (Structural Insulated Panel) structures are now used for many structures including; new build houses, apartments, extensions and roofs as well as being used for larger-scale structures including; Commercial Buildings, Churches, Schools, Colleges, Leisure Facilities, Community Centres, Retail developments and Outlets, Hotels, Restaurants, Supermarkets, Hospitals and Doctors Surgeries.

The insulation properties of the SIP panels make them extremely energy-efficient, keeping in the warmth during the winter and the heat out during the summer, saving you considerable costs on your energy bills when your extension has been completed, as well as being able to use it all year round due to its regulated temperature. The joining system of a SIP structure offers extreme airtightness compared to traditional brick, stone or timber method structures and this, as well as the insulated panels, result in a strong, well designed, warm, efficient and eco-friendly extension.

Overall, building a SIP extension is a quicker and more effective way to increase the space in your property. The SIP framework can be constructed in as little as 2 days so it significantly speeds up the process of adding an extension, as well as dramatically reducing the labour costs of the construction. They can be used to create strong, highly energy-efficient extensions and will revolutionise the way you think about extending your home or business.

Adding a SIP extension to your home or business with a Guardian™ Warm Roof gives you added living space that you may have been looking for without the need for moving house or adding a traditional extension which can be costly.

SIP Extension FAQ’s

Do you need planning permission for SIP extensions?

It varies from case to case whether you will need planning permission for a SIP extension and its normally dependent on the size of the extension you want to build. Guardian Roofs UK has a vast amount of experience of SIP extensions and will advise you about this at your planning and design stage.

Most extensions require planning permission whether they are one or two storeys, front, back or side, porch or a conservatory. In England, PD (Permitted Development) rights allow up to an 8m long single-storey rear extension on a detached property, and 6m on semi-detached and terraced houses without planning permission. If your SIP extension is within these dimensions then you will still need to notify your local authority and they will consult with your neighbours. If your neighbours object to your extension then the local council will look at the impact your proposal has on yours and your neighbour’s surroundings. Be aware that in some parts of the UK, the limits are 4m and 3m so it is always a good idea to check this before you start to plan your SIP extension. Guardian Roofs UK will advise you about this at your planning and design stage.

SIP’s won’t normally raise any issues if you do need to planning consent and building regulations for your extension. If your design is in keeping with your home and the properties around you then this is what is normally looked at and they are now an accepted construction method by local authorities.

As with other traditional builds, a SIP extension can have traditional cavity and brick or stone wall, render, brick slips, timber cladding, slate, copper, zinc, stainless standing seam and your external finishes will be considered as part of your planning approval request.

What is the U Value of a SIP extension?

U value is a measuring unit which tells you how much heat is lost through a building. It is measured in metres squared Kelvin per Watt (m2K/W) and the amount of heat that passes through the fabric of the building over a year. The lower the number the better and SIP extensions are extremely thermally and energy-efficient. They should come with triple insulated walls and roof, double-glazed windows and strong, steel-reinforced structures which makes them strong and durable, lasting for years and years. You should always check this when you are looking for a SIP extension company and look for outstanding energy-efficiency with a U-value of 1.0 W/m2K or less as these are the most energy-saving extensions available.

Do you need an architect to design SIP extensions?

A SIP extension offers you complete freedom when it comes to design and you don’t need an architect as your SIP extension company will help you with your design, giving you inspiration and ideas along the way and take your exact measurements. The pre-cut panels interlock together which enables you to have different shaped rooms within your structure to make the most of your space, leaving you with a strong, environmentally friendly, modern design. You can have sloping roof panels which create an open feel which will maximise the feel of space within your extension. The exterior can be brick slips and this is the most popular option, however, more and more people now are choosing to clad their SIP extension exterior and there is a wide selection of colours and styles to choose from. You can also choose to render your SIP extension exterior if this is more fitting with your home and it can be painted in a wide range of colours.

Do I need to arrange a builder for my SIP extension?

A professional and reputable SIP extensions company like Guardian Roofs UK will help you with the design of your new extension and will make all the arrangements for its construction so you don’t need to find your own tradespeople to do the work. Good and reliable builders are hard to find these days and this is another benefit of a SIP extension with Guardian Roofs UK, you design it and then sit back and relax whilst we do the rest.

Will I need to decorate a SIP extension inside?
