    Our east facing 1972 conservatory leaks like a sieve. All the glass is blown & the all doors are beyond economic repair. Yah!

    We are moving in a max of three years so I want to do the best vfm job I can to deliver a usable space for the next owners. My 'idea' is that I build a solid wall to the north side, replace the roof with a solid one and highly insulate floor, roof & walls to make it the usable space it needs to be.

    Has anyone done anything similar? What was your experience like? What do I need to consider? Got any advice?

    Thanks
    David :cool:

    btw if this is in the wrong place pls feel free to move it :bigsmile:

    You probably know this already, but once you make it a 'real building', and not a conservatory, it needs to jump through all the Bldg Regs hoops that a conservatory mainly does not. Have a look at the target U values for extensions in Part L of the Bldg Regs. If you are only building a (solid?) wall toone side do the other 2 remain glazed? That could end up a high proportion of the whole wall area, and need area-weighted U value calcs to show that you have made up the 'deficit' elsewhere.

    Do you have friendly neighbours?
  2.  
    What is the construction of the conservatory ? upvc or wood, any brick dwarf walls etc. The construction type will alter the cost quite a bit and change the ease of modifications.

    Are you sure that the new owner will want (and therefore pay for with an uplifted price) all the modification you are proposing to do.

    With all the glass blown and the doors needing replacement sounds like close to a rebuild.

    In terms of value to the house a glass roof is not as good as a tiled roof. What has yours got (or will have)

    As said above any issues with building regs (or planning)?
  3.  
    If you are replacing the roof, a wall and modifying the floor, then consider knocking the whole thing down and starting again with a knock-through extension room that does what you really want and adds value and sales wow factor.

    Just had this debate with my parents, they'd had a conservatory for decades and recently replaced the roof with fake slate and replaced the glazing. It was compromised because the structure wasn't strong enough for a proper roof and the roof slope was too shallow. It is still just a little too small and the floor level still isn't quite right, it's thermally bridged, and looks a bit of a bodge. But having lived with it for many years they couldn't imagine a step change of getting rid of it and starting afresh!

    I think in your situation I would go for an "orangery" type extension. With this you could have some solid walls but a flat roof with a lantern structure on it. Easier to insulate. There are some restrictions as I recall if you want to avoid building regs - would be wise to check first with your local authority.

    I wish I had gone with this type of design instead of a conservatory. Admittedly we did save a lot of money by buying a really good quality DIY kit (£7K vs £15K for having one professionally built). Unfortunately we have the age old problem of the conservatory being too hot in the summer (south-east facing) and too cold in the winter.
