The make and style of conservatory does not normally impact need for planning permission. For example, convention materials for conservatory construction are timber, aluminium and uPVC and these do not impact planning issue. Similarly style such as period designs like Victorian, Georgian and Edwardian is not important to this issue. Lean-to conservatories may have some bearing depending on height of roof relative to property.

If you are considering a patio awning attached to conservatory then this should also be OK, but a quick phone call to planning department is always sensible.

If you are ambitious enough to build conservatory yourself then definitely check with local building regulations and planning department. If you don’t and mistakes are made it could become a very costly business, so follow golden rule and always check. If conservatory is being built for you, then your retailer should guide you in right direction, but always check with your local authority as worse thing that can happen once you've built your conservatory is that you have to take it down.

That brings up another important issue in planning stages, a budget. You will need to determine what total budget your willing to spend on this project. Without making a budget price can quickly escalate out of control. A kitchen project that started at an affordable $15,000 without budget parameters can quickly turn into an $80,000 renovation. This will likely end in frustration and no new kitchen. Set limits early and then work within those limits. When you have your spending limit figured out take off a percentage for unforeseen costs. They will almost always come about at some point. At least 15% in my estimation should be allotted for cost overruns, and that is pretty conservative.

If you do decide to do project yourself or become your own GC, make sure you will have time to do it. In most kitchens, especially in homes with children, not having a kitchen is a major inconvenience. A husband, who drags his feet getting a new kitchen installed, will find himself in doghouse faster than fido after he chews up couch! The best advice I can give you is to do your homework. There is so much great info available on internet today that it isn't too difficult.
