My Cookery School in a "Conservatory" written by homeowner, Mrs B

The Property Sunnedon House was built in 1870 in the historic village of Coggeshall near Colchester. Originally built by a factory owner who manufactured Isinglass, the building was sold to the Church of England in 1920 who ran it as a charitable home for unmarried mothers for 40 years. References to the house can still be found on adoption forums to this day. In 1960 the building was bought by a renowned London artist who divided the house into three properties, the middle of which is now my home. In 2012, after 18 years of living and working in London, most recently as a partner for a global management consulting firm, it was time for a change in career and lifestyle. Having completed the diploma course at Leith’s School of Food and Wine when I was younger and with a background in catering, I decided to start a cookery school giving day lessons that are fun, inspiring and help participants improve their cooking skills. I engaged Searchwells, a property search agency, and asked them to help me find a character property in the Essex countryside that had enough potential and space for a cookery school. Originally I was looking for a small cottage with a large outbuilding I could convert but as soon as I walked into this property, despite being different to my original brief, I fell in love with it. However, it did mean that with no outbuilding I needed to develop a different plan to house my cookery school. The Build When I moved in, the house had a basement kitchen, which was very charming as it contained the old original wine cellars and had lots of original features but although it provided lots of storage it didn’t have the space to run cookery classes. There was also a small conservatory to the rear of the building, which, whilst it added considerable space and footprint to the house, was unused because of the classic ‘too hot in summer, too cold in winter’ issue that you get with some conservatories. I knew I needed to adapt the house in some way. The best option seemed to be to use the existing conservatory but it was too small and therefore needed to be adapted and extended to be made suitable. I also didn’t feel that the conservatory in its current form complemented the style of the house. At this point, I decided to seek help from a professional. As I didn’t know Essex well, having lived in London, it was Searchwell’s who recommended Westbury. I first met Jonathan (the founder) from Westbury in August of 2013, and after meeting with him at the Westbury workshop and explaining what I was trying to achieve I decided not to investigate other companies as I liked his ideas so much, and the quality of the workmanship was clear. Jonathan suggested tearing down the unused conservatory and adding a garden room to house a kitchen extension in its place. As this would add to the footprint of the house, we needed planning permission, and much to my delight, after finalising the designs, Westbury took care of this, so it was no hassle at all. One of my main concerns was whether the new garden room would get too hot, especially with it being south facing and home to a kitchen. However, Westbury worked solutions into the design as a matter of course, including extractor fans in the ceiling to cool the room as well as to remove cooking odours as I have induction hobs incorporated into the kitchen island. They also suggested incorporating an outside tap and lighting into the build, making it truly practical. It’s these details which really set my mind on Westbury – they really did think of everything. After planning permission was granted, the build commenced late November/early December 2013, and took only eight weeks. Westbury worked hard to ensure that the new extension would fit with the original design of the house, with the fascia and soffit mimicking that of the main building in both design and colour. For example, blue beams and a circular window were designed into the gable end of the house to mirror the woodwork and the circular window seen in the main house, above the new extension. To complete the new space, Westbury recommended kitchen company Nicholas Anthony, who designed the layout and décor of the new kitchen and the fit out was complete in April 2014. The Cookery School The new kitchen extension is not only a great family kitchen but is perfect for my cookery school, The Green Apron which I launched in Spring 2016. The original basement kitchen is also still in place and acts as the ideal storage and preparation area for cookery school classes and all the washing up is instantly whisked downstairs. The cookery school has proved popular. I host day classes for all abilities with a variety of themes; Everyday Italian, Cooking Fish with Confidence, Vegetarian, Baking, and Thai and Moroccan cuisine. The new garden room is big enough for a sizeable kitchen island, which allows myself and up to eight course participants to all cook in the same space so classes are very relaxed, sociable and fun. Having the garden room as part of the house rather than as a standalone construction in the garden has also enabled us to use the garden really comprehensively. Westbury recommended a landscape gardener who redesigned the outside, creating a beautiful patio area which is perfect for entertaining or relaxing in summer. As well this there is a lovely lawn area, space for my chickens and a sizable vegetable patch which is a real boon for the cookery school; using homegrown, organic seasonal produce is very popular with class attendees, and makes the end result that bit more satisfying to eat! The Experience Westbury made every step of the process very easy, from the initial concept, to the planning permission, to the build itself. Jonathan visited the house and immediately understood what I wanted to achieve and explained how it could be done through the garden room design he conceived. Right through the process both he and the team at Westbury managed my expectations well; Sally, my first point of contact, was there every step of the way, proactively providing me with information and timescales as the project progressed. To top it all off, the garden room has a generous guarantee and the few niggles I’ve had in four years, such as a door handle becoming misaligned or a window lock not securing properly, have been resolved within a day or two of my phone call. I am completely delighted with my garden room, spend all my time in here and couldn’t imagine the house without it now. Westbury has been brilliant throughout the whole process and I would wholeheartedly recommend them to others.

Yes, thank you for your comment. We have spent so long trying to decide whether to try and use the old kitchen and extend it into the new bit. Suppose we would use it as a side entrance and with your idea would be able to close it off even further.

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.

Hello, if you don't want sight lines then I wouldn't have Crittall to be honest (unless you wanted Crittall without the cross bars of course?? as they are super busy and won't give you a clear view of the garden) We opted to go for bi-folds with slimmer sight lines and wider panes so there would be less lines. On your size opening, it would take 3 bi-fold panes which means the central one is just glass. If you had sliding doors then you would likely have 2 panels with the bar being right in the middle (unless you can slide them into pocket doors!) Bi-folds - they even do frame-less bi-folds now or ones with the lines super narrow so I would get prices for those. It also depends on your garden - as you say, because we had the bi-folds leading directly onto a patio area. If you have to step down then the garden will feel quite separate anyway and so you don't benefit from having an open 'room' as you would with a semi flush or flush threshold and bi-folds doors. In that case, Alu french doors with side panels that don't have all the cross bars would likely be the cheapest option for you.

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.

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.

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 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...

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.

Both would be lovely aspects of a house but I have to say that an extension is more practical for the exterior of a house. It also easier to use my favourite type of door, sliding, glass doors! A conservatory also seems (to me) that the walls are closing in around you. However, an extension is airier as the building has been extended. This means you could add skylights which makes the atmosphere and general look of the extension lighter.
