Your family is growing and a need for space is felt? You are thinking about a conservatory from where to enjoy the garden view or you simply think more meter squares can add a plus to your home? From first glance, there are no restrictions to extend the house after completion. Nevertheless, there is a few things you might like to consider and steps to follow first: where should be the extension? Is the project manageable? What is the dedicated budget? Do I need a permit (depends on the size of the extension)? Etc. You can ask the opinion of an expert before starting your project to know if your idea is feasible or needs a few adjustments.
