Hi Catherine, Check out our video online of a ConservaBase being installed. These are Conservatory Steel Bases that are designed to go over drains or man hole covers. Have a look at the video and we can advise you on what permission you need to do this. It's quite common and easy to do :) If you have any further questions, or if you would like a brochure pack, please do not hesitate to give me a call on our free phone number 0800 952 8000. Best Regards Rob Smith

Can an extension be built next to a conservatory?

Yes if you can speak to them they will give you advice normally. Paying out for plans when you have no chance of success is a waste of money. What about a sun room or converting your existing conservatory to an insulated roof?

Thank you for your views Jonathon. So, when you suggest changing layout what do you mean? We initially looked at through our existing patio door having a door straight out to garden but decided this would limit space internally like you mention and also be a bit of a wind tunnel. So the design is through our existing patio/ a full wall to right , windows ahead and the external door out to the left (longest part). The dimensions are 3.5x4.5 with the shortest part out the garden and length along house. Leaving living room window on right open for light.

Hi, I've got a conservatory that faces SE and it does get very hot, not just in the summer but also in spring when the sun is low and shines directly in. It is lovely in there on the right day though. What I've done to manage the temperature is: kept the exterior-quality doors between the conservatory and the house so the house can be kept cool even when the conservatory is oven-like, the roof has a reflective surface to reduce some of the rays, the windows have both blinds and blackout curtains which I close on the sunniest days, the furniture is heat and fade resistant, plants have to be moved out on the hottest days. The above makes it sound like the worst room in the house but actually it is lovely so long as it is carefully managed. Good luck, whatever you decide.

Conservatories give very poor heat management. In My experience most tend to be freezing in winter and uncomfortably hot in summer.

A conservatory with a hi spec glass roof would be much brighter as well as being able to retain heat and deflect heat for example celsius glass

We agree a high spec glass roof can be very good but even an excellent overall U value achieved of somewhere in the order of 1.2 is almost 7 times the heat loss of the minimum 0.18 required with a solid roof meeting building regs

We find that the majority of our clients opt for a semi glazed extension rather than fully glazed. This has practicalities in terms of temperature and year round use, but also in the placement of lighting, furniture, wall art etc. We find that the right balance of masonry and glass provides a fantastic and functional living space and, done right, will add value to the property and, more importantly, the homeowners lifestyle.

Both have their merits, however given the requirements for Building Regulations and the limits therefore imposed on levels of glazing, providing a Conservatory / glass extension would be difficult to achieve within u-values etc. This means a conservatory would need to be a separate room and not what clients are looking for. To open it up to the house, SAPs would likely be needed and costs could escalate anyway. It also depends on the use as conservatories really only offer seating areas, whereas extensions offer a wider choice of use. Therefore we would recommend extensions for function and performance.

Over time I have always found an extension more useful throughout the full 4 seasons, where a conservatory is prone to both over heating, or being rather cold/hard to heat. Good luck though, whatever you choose.

Interesting recent comments! We believe solid roof extensions with substantially glazed walls are better for many of the reasons recently posted and will increase in value along with the home. Although we like conservatories and understand how they can allow light to an adjoining room and have a different 'feel'. Unfortunately long term they generally do not add value and indeed can be seen as something in need of upgrade therefore adding very little or no value at all.

If you like the feel of a sunroom and to help keep cost down it is certainly worth looking at the Celsius solid roof which gives a great U Value and the appearance of a tiled roof at the same time

It's a common assumption that a conservatory will be too hot in the summer and too cold in the winter. This can be true! Regardless of frame material, if there is inadequate ventilation or incorrect glass used, it is just as true today, as it was in the 1980's when Solar Control Glass wasn't available.

Many people will have experienced problems with older conservatories because of the materials available at the time. However, there is no reason for a conservatory or orangery to experience this now... it's all about FITNESS FOR PURPOSE.

The main reason many conservatories are still being built which are "Too Hot in the Summer and Too Cold in the Winter", is the poor quality advice, design & knowledge of products available to provide a solution; often the case at the lower end of the market where making a sale at any cost is often more important than having an interest in the clients needs. As a result often a conservatory or orangery is designed with inadequate ventilation, no roof vents and the lowest specification glazing.

Contemporary Oak Conservatories · More Info

Another key factor to consider when having a well-designed conservatory or orangery is sufficient natural light not just within the room itself but that of ensuring it is also provided to the adjoining existing room; something that is often forgotten about or not advised about at the design stage.

Richmond Oak specialise in oak conservatories & orangeries that are designed & built to ensure they are a habitable living environment all year round as a result of using high specification glazing 0.9 U value in the roof glass 1.0 U value in the frame glass, sensible ventilation and under flooring heating.

Extensions are great all year round. They keep heat in the winter and stay cool in the summer, adding a roof a lantern means you still get plenty of light in your new rooms.

Extensions are usually preferable because in Scotland a conservatory is classed as temporary and is not allowed to be connected to the main heating system

Richmond Oak make very valid points for a well specified conservatory or orangery and in many situations these are great options However even modern high spec glass and frames combined is unlikely to give a U value (heat loss) better than 1. 0- at least 6 times the heat loss or heat gain of a Delta solid roof.

Ultimately it comes down to how you want to use the space. If you need extra floor area for all round use then a conventional solid insulated roof is essential. But there is something about the quality of sitting in a warm sunlit conservatory in spring and autumn when it's too cold to sit outside that can't be beaten! A nice inside/outside table that lets you move completely outside when it's warm enough allows you to seamlessly adapt to the seasons throughout the year...

It is usually more energy-efficient to build an extension, although orientation and other siting factors will play a part in each individual situation.

Building an extension will always allow you to integrate the new space into the existing rooms when you want to have an open plan kitchen/dining/sitting area. Conservatories need to remain as a separate space due to the hit loss in winter or over heating in summer time. Creating an orangery is the best option in case you want the glazed space to be part of the house.

Replacing conservatory roofs with tiled roofs will generally need building control approval although a minority of local authorities say not. Be safe and always apply or use a company with JHAI certification to ensure a quality job and no problems if selling property.

Solid tiled roofs are definitely usable all year round provided they are properly insulated to meet or exceed building regulations

Many ' cladover' jobs would not meet regs or get approval so beware

If you were our client, we would first assess which way the house faces in order to understand the direction of the sun and the likely impact on the space in terms of light and heat, plus we would ask what use you intend to place on the new space. It is also the case that with whatever heating - a fully glazed conservatory can seem an inhospitable space in the winter months.

Even in the UK heat gain during our short summer is a major consideration and whilst roof blinds can be added - these can spoil the original design intent. A part solid / part glazed roof with fully glazed walls may be the most successful.

Depends on the house. An extension with bi fold doors and lantern to the flat roof, appears the way forward. For many houses this is the correct decision, providing a large light filled room.

But a conservatory gives the ability to sit in the garden. To hear the rain. A room not filled with light but to sit in the light. Modern glass roofs and windows are so different to the early conservatories. We use ours 12 months a year. It can also be used to bring heat back into a house.

A conservatory, even to modern standards, is so much cheaper than an extension. So small extension or large conservatory? Large conservatory every time.
