Do you live in a Victorian/Edwardian house and have you had a rear extension?

We live in a large 3 bed semi detached Edwardian property that already has a rear extension added but I’m interested in extending the kitchen to the side of the house to take in the whole width of the back of the house and wondered what I need to consider and also price? I know this will vary massively (we are NE England) but just looking for general ideas really and things to consider.

we have a large yard area to the rear - the garage is on the side of the property so don’t want to cover the back garage door but there’s about a 3ft by 10ft area I’d like to extend the kitchen out to and have a glass or lantern roof and use as a extra living space.

in my head it looks fabulous but I don’t have any idea of extension build costs.

it would be single story and would involve pulling down an exterior wall and essentially moving it out by 3ft. I know it isn’t that simple just to help give you an idea. Can try and take a picture if anyone wants one 😂

just looking for people’s experiences please.

TIA

Side return extensions which this sounds like are £200k + where I am at the moment but it’s London so possibly not reflective of prices near you

This. We did ours recently. But IDK if the NE would be cheaper than London and if a semi rather than a mid terraced like we are might be more efficient because they can get machinery in and don’t need to do it all by hand… Also we couldn’t live through the disruption so had to move out for 6 months.

foodiefil · 29/10/2025 13:51

Oh bloody hell 200k! Excuse the absolute tip of here but this is where I’m thinking so yes quite narrow but the kitchen is quite big anyway but not big enough for a couch seating area. Not even sure if an extension this size would allow that anyway tbh. Might be dreaming with my eyes open

It is very expensive, and IMO a large house is always better laid out than a smaller house with bits tacked on.

The buyers of my previous house pushed out the back, and had big problems with a neighbour.

HillOf · 29/10/2025 14:25

I think that’s likely to end up very expensive for not much additional space, OP. We’re doing something similar at the moment, but have a large side garden, so the space we’re gaining is far larger — a whole new kitchen/diner and hallway. But it’s been an enormous job, and very expensive. I wouldn’t have done it, I think, for so little space gain,

foodiefil · 29/10/2025 14:27

We don’t need the space, I’d just like the space and to use up some of the dead yard to the side of the house. We have a large garden so don’t need it to sit out in. The house is 170 square metres and has two reception rooms already I’ve just lived in a house before where there was a couch/tv area next to the kitchen and really liked it 😂

Seems like it would take a lottery win (which I don’t put on)

P.s.

Trump's planning a 90,000 sq ft extension to a 55,000 sq ft residence. It’s like adding a conservatory twice the size of your house.

Apparently the gaudy new ballroom will accommodate 999 people.

That's a lot of balls.

Only 999! Why not 1000?! Squeeze an extra one in wouldn’t you 😂

Did similar to what you would like @foodiefil 5x2metre side extension with a roof lantern they didn’t demolish the whole side wall just took out the side window & back door left supporting walls either side & squared up the opening the dining room window was knocked through into the extension & we added reclaimed pine/glass double doors, admittedly wasn’t a huge space but gained enough for the small kitchen table/chairs that we can walk around rather than being against the old kitchen window plus have a sofa & nice cupboard/table either side of the sofa, had French doors rather than bi-fold, this was about twelve years ago so cost wise very different from now it was just over twenty thousand pounds, which included everything apart from flooring which we paid for separately & they laid, I don’t regret doing it as even relatively small extension really made the kitchen much more comfortable & we still have a good sized patio just utilised the wasted side return.

Thank you so much - pleased you’re happy with it. I know it would feel bigger than it looks and atm that space is just wasted. The outside space I mean.

Possibly less than three feet, as a modern, insulated, cavity wall could well be quite a bit thicker than the current outside wall!

I suspect that the cost would be completely disproportional to the space created. If you want it to be one open room in the new kitchen then there's a whole lot of steel needed to support the house above the current exterior wall, and probably hand dug foundations. For a 1m by, what, 5m? extension normal cost / m2 won't apply. For a 5m x 5m extension you might be able to work on a £2k to £3k/m2 costs for estimating purposes. But I wouldn't be surprised if you didn't end up paying a similar amount in total to that (£50k/£75k) for what you are proposing, if done well. Costs based on SE

Yes, I can’t even remember what our steels cost — a truly terrifying sum…

It will take a lot of hot air to heat all that space ;)

dontcallmelen · 29/10/2025 16:47

It’s going to be most Bigly beautiful ballroom of all time.

Side returns are expensive in terms of square footage but do make quite a big difference if you are looking for a big do-everything kitchen. Whether it's worth it financially will depend on house prices where you live- probably more likely to be worth it in more expensive areas. You also need to think about it will affect the light in the rest of the house- I know a few people who ended up with lovely wide kitchens but dark miserable sitting rooms. because they lost the french windows at the end.

Our sitting room is at the front of the house the room the extension would be added on to (so to speak) is what we call the library, a second reception room. Would probably need an architect to show us how much we’d gain and if what I want to be able to do there will work.
you know once I’m rich, any day now, any day

I’ve recently had a 7 x 2.5 m side extension. It has made a massive difference to the previously very long narrow kitchen. Cost c £120k including full rewire and kitchen and some reconfiguration. It will have increased the house value but not necessarily as much as it cost. There was a lot of structural work which would be needed for a narrower one so I think you’d get a lot of cost for not much space.

I’d recommend staying away from architects for now and find a builder to give rough costs. We ended up getting a structural engineer recommended by the builder to redo the plans as we couldn’t afford the lovely beam free plan the architect designed.

rockstarshoes · 29/10/2025 23:26

I think that would make quite a big difference! We went out 2 metres internal at the back of our house ( went sideways as well) but it gave us loads of extra space.

Get a couple of quotes & see?
