Getting to grips with your home extension build time-line ‘diary’


When you are considering a home extension, we at Mint understand that a clear idea of time-line – or at the very least a considered planned estimate and idea of the time-line is really quite key and can be very much a part of decision to go ahead with an extension now or later or even not at all for the foreseeable future perhaps.

It’s a fact that we at Mint do find that no two extension projects are the same for all kinds of reasons, and the time-lines, in any event, differ dramatically depending on the size and complexity of the project or even personal matters and issues involving day to day life in many respects of the clients day to day situation.


However, an example time-line to give you a rough idea of the key milestones in a typical extension project is of course useful as a guideline as is getting an idea of the order in which key tasks and project milestones are likely to occur.


Also, an approximation of when key elements of any extension project might take place will, of course, give those involved the chance to get organised in terms of managing their lives around the build. Any time-line plan will help highlight key periods where major decisions have to be made on your part, or when disruption to your daily routine is likely to take place.
