Would you buy an old flat near Canary Wharf and spend big on renovating it, or just buy a house?
Post
Trying to work out whether I'm being sensible here or making a very expensive emotional decision. Our friends are moving countries and can sell their apartment directly to us for 455k, a small discount. We're looking at an older, good sized 2 bed / 2 bath flat in the Isle of Dogs, very close to a DLR station. It's in a small older block, but with a green quiet area, tons of natural light and fantastic western views over the docks and towards Canary Wharf and gets really nice sunsets. The problem is that internally it's basically stuck in the 80s/90s and needs a LOT of work. We're thinking: Introduce water-based underfloor heating throughout Replace old chipboard squeaky flors with engineered wood Full renovation of both bathrooms New kitchen Replacing all of the windows New combi boiler and updating the old plumbing setup Skimming the ceilings and walls throughout New internal doors and frames New lighting Built-in joinery / TV wall / storage We've had multiple builder quotes and we're currently estimating roughly £100k-ish all in for the labour, materials and windows. Some comparable dated flat sale in a similar block sold for £490k, while another similar-sized one in much better condition sold for £545k So the question is basically: Is it worth spending £100k renovating an older flat in Isle of Dogs? I know renovations don't always add £1 of value for every £1 spent, so I'm trying to work out what the finished place would actually be worth, especially when apartment sales have been suffering in London. We are going to live in it, we don't want to flip it. However it is still a stepping stone, and we'll probably sell it in 5-6 years once the family grows. I'd still like to make a good financial decision. So, after the 100k renovation, would you expect such an apartment to be worth something in the mid/high £500ks ? Or would the age of the building and £4k-ish service charge put a hard ceiling on it? The alternative is buying a house instead and putting the renovation money towards the deposit, but that will get us a 570-600k house somewhere in zone 5-6. I know "buy the house" is probably the standard Reddit answer, but we'd potentially be getting a much less desirable location for us. So what would you do?

Summary
The post is about a major renovation and explicitly includes replacing all windows, but the main focus is overall property investment rather than a window-specific problem.
Reasoning
This is a strong home renovation and purchase-planning post that mentions window replacement as one item in a larger scope of work. There are no signs of window damage, drafts, condensation, or comparison of window products, so the window intent is moderate rather than high.
