@cookster remember mate. A bike in the conservatory is worth more than a bird [in a] bush. Roll on the good times.
Right. This has come up before; some have checked their house insurance and were told that a bike in the house invalidated the cover (enticing theft, fire risk etc).
I think it is lame and pretentious unless you are a rock star or a racer and have a massive purpose built display room with all the associated wall hangings and stuff (yes, I have thought of doing this myself and come to the same conclusion). Anything less will just look desperate and sad and in a couple of years time you will think; what the fuck was I thinking of? Go for it!
The bikes look great in the house, conservatory's are handy, warm and dry places to polish them too during the shit winter season, plus close to bacon sandwiches, hot drinks and music. Don't know about heat related hassels as I've never kept one inside during summer. Maybe that will change this year! I bought some super hardwearing black office type carpet to stand mine on so theres no marks or mess from the odd small jobs. In summer I just pressure was it off and it dries in the sun in a day. Go for it.
