Hi grahroll,
apparently the external ones are cheaper but internal suits our need - so we don’t have to go outside your house at night for example. I think external ones are great for accessing the house (like a Queenslander) that doesn’t really have downstairs rooms - you just access the whole house via the lift.
We are going to consult with an architect, but even they may not be abreast of the latest and greatest versions - particularly as their clients are most likely to not have to worry about money. Appreciate your help.
