aluminium conservatories

jaks101

Hi,

Rather than moving me and the wife were thinking about building a conservatory at the back of the house.
I want one that is 3m deep by 5m wide, the reason for the width is that i want it to cover both my rear patio door and also my kitchen door as i want the conservatory to be open and flowing with no doors so it is part of the house rather than a cold room that never ends up getting used.
I want to have radiators plumber in from my current central heating system.
I presume I am going to need planning permission due to it having no separating doors.
I will arrange for all the work to be carried out myself I.e building the dwarf wall and floor electrics etc.
I'm struggling to find prices online as to the cost of aluminium framed conservatories. I want a reasonably High quality finish and a glass roof with good quality low U value ratings.
As I'm only in the peliminary stages of weighing up how much it will cost I'm just wondering if anyone can give me a rough idea of cost
I am after a simple lean to conservatory but with a decent pitch roof 3m high at the highest point down to 2.2 roughly taking into account the dwarf wall
Can I build one of the side walls out of brick (towards my next door neighbours property) As I dont see the point in having it made of glass to have it obscured out.


Any ideas guys and gals??

Do you live in a terrace, semi or detached house? If it's only 3m deep and provided it's to the rear of the original dwelling (and not to the rear of any subsequent extension), then it will probably be permitted development and you won't need to submit a planning application.

In terms of planning - the materials don't matter - can be brick, glass or timber - they're all extensions when considering if they require a planning application or not.

The fact that it will be open to the house will throw up some issues I believe in that you may have to beef up insulation etc in other parts of the house to meet overall insulation values for the house. Sure someone else can clarify more so

We have an open plan conservatory to our kitchen diner and whilst it does indeed create a nice open space and is very nice during the warmer months, during winter, unless you have some way of closing off the conservatory you will find it extremelly cold and very expensive to heat unless you spec up the glass to the max. By the time you have specced the glass up you mauy have been better off building a proper extension with plenty of windows/doors/skylights, which will be much mich more useable

Do not underestimate how cold it can get with an open plan conservatory - sliding doors may be best compromise to shut it off during the really cold months

It's a big no-no, thermally, not have closable doors between a house and a conservatory. But if you want to waste your hard earned cash heating the garden with your conservatory then, by all means, go ahead.

would a vaulted cieling tiled roof make all the difference even if i have lots of windows in the extension/conservatory.

I 100& want to have no closable doors between the existing house and the extension so the "garden room" option may be the way forward.
I have one further problem due to the way my garden is situated on a hill I will have to build over my sewerage pipe there is no way around it. I think building the brickwork and using a lintel over the pipe so there is no weight on the pipe may be an option and also having a timber suspended floor instead of a concrete one incase the worst may ever happen. ideas??

If, by a vaulted ceiling, you mean a properly built extension to the house, then yes. It all hinges around the insulation values of the structure. A conservatory has a very high heat loss, so if the conservatory is open to the house then the insulation value of the house is seriously compromised and would not be permitted I suspect.
If you build a "proper" extension, then the insulation values are specified in the building regs and the losses from the extension would not compromise the total insulation levels of the house.
Putting lintels over drain pipes is quite normal practice. You are unlikely to require access to the pipes, only to any inspection chamber which might be under the extension. There are various ways of maintaining access. including a suspended wooden floor. They will all involve an access hatch of some type.

there are no access or inspection chambers as I am the last on the run or first on the run which ever way you look at it.
I had problems with the drain a few years back and had to have bits dug up as the pot pipes had disjointed several parts of the pipe were replaced with small sections of repair.
The pipe was never fully replaced and it was only 5m long to the neighbours property. I think I may just replace the whole pipe with a new heavy duty plastic pipe just to be sure before I build the extension/conservatory.

If I were to build a extention with a tiled roof will I be able to put as many windows as I like or will I still be limited by the insulation issues.
I wanted a 2.5M Bi folding foor and a big panoramic window across the full rear wall

One more question, If my land is back filled land as I live on a hill will I need to have pile foundations?
