Cost of an extension - £100k

[Guineapiggiesmalls]

I know this is a rather vague question, but I really don’t know where to start/if we can start!

We’ve had a windfall of around £100k and know we are exceptionally lucky. We’ve always spoken of extending our 100 year old bungalow but now that it’s an actual possibility I’m a bit lost of what we can actually afford?

Just to give us a bit of a steer, could anyone tell me if they’ve spent similar and what they got for that? I feel cheeky asking, but have no idea where to start!

We've recently spent a similar amount on a single storey extension with open plan kitchen, French doors, underfloor heating and a few walls moved.

South east.

What do you want from your extension? You'd be best having a particular need or project in mind rather than working out what you can spend £100k on. Also see what neighbours have done. Will spending £100k add more than that to the value of the house?

Thank you :) what I really need is Kirsty allsop to come and tell me what to do!

I expect what I want is probably out of our budget (double storey + loft conversion), but I think I would also be happy spending the money getting the basics done and potentially upgrading the fittings in the future.

We've recently extended and renovated a Victorian semi. The 20 square foot double storey extension was about £100k for the build, not including internal finishing. Quote for loft was about £40k but we didn't do it - good decision as it would have been way more complicated than the architects accounted for, and would have cost more.

If you’d plan on going to two stories in the future let the builder / architect know when you initiate as the requirements for the foundations may change. Putting in stronger than needed now may save you a lot of mess if you do go ahead in the future. Otherwise, 100k should get you an extension I would have thought as long as we’re not talking 50 metre squared orangery or something.

Your starting point is rough drawing of what you want, which may just be a simple box. I’d be inclined then to engage an architect / structural engineer to turn this into schematics. You then have something concrete to send to builders for quotes. As it can be quite hard to get a builder in at the moment, having the plans in hand shows you’re not a time waster, and it will also allow them to quote far more accurately.
