Hi all!
A bit of background first of all. We moved into out new home just over 2 years ago and initially we had the idea of doing a 2 storey extension on the side, which would contain a utility room, home cinema/games room and two bedrooms. We got planning approved for this and all seemed well.
Since then we've had the credit crunch and are not able to borrow the amount required to complete this build. We've also had a rethink after living in the house for sometime and we now feel that there are better options available. We have a pretty large garden which contains a summer house and shed. We don't really use the summer house at all so the idea is basically to replace it with a garden building which would become the home cinema/games room.
Here's a view of the area of the garden in question. It was taken a while ago but the area in question is basically still the same.
The idea is to replace it with a building like the one shown below (photo courtesy of greenretreats.co.uk) running down the hedge with the doors facing the house (which is just behind where I took the above photo). There would then be a path from the building to connect it to the existing patio (just seen in the above photo). The windows in the building below are optional and I would not be including them. The projector would be positioned at the back of the building and the screen would pull down over the door (which would also be fitted with blinds to black out the building when required.

Power would be run to the building via a cable layed along the hedge line, through tubing burried in the ground. There would be either two chairs or a 2/3 seat sofa at the back of the building and also the equipment rig with Amp, Consoles etc. would also be at that end for easy connection to the projector. I already have an HD projector (albeit a now rather old Sanyo Z3) and a pull down screen which would fit the width of the building. The internal dimensions of the building are 2m x 3.85m which gives good proportions and a decent throw length for an 85" screen. These building can also be well sound insulated as they are often used as music studios.
I've had a bit of a search on here for similar projects, but have only found this one (

LINK) which is more of a custom build and this one (
LINK) which again is more of a log cabin build.
What are people's views on this so far. Not sure when i'm going to be able to afford to do this (probably early next year) but it would be great to hear the thoughts of some more experienced folk (about potential pitfalls etc.) before I really get my hopes up.
Cost of the building should be around £8,000 including VAT and any extras. I've pretty much got the equipment I need so other costs should be minimal and I expect the whole thing to be around the £10k mark.
