It’s a tough cookie to crumble this one, but we’re going to try. So you want to know how much it costs to get one of these lovely big kitchen extensions in London? Preferably on a Victorian
For a rough estimate, we’re going to assume you have middle ground taste in finishes, kitchens and bathrooms with the odd splurge luxury to bring the whole lot up a level and a few eBay finds thrown in for good measure and character (often the kind of mix we like). To keep it simple, we’ll also assume that your extension is going to be 3 meters which, unless you are in a conservation area will mean it falls under permitted development and therefore no planning is needed.
To start with you’ll want your building plans, structural calculations and to instruct a Building Regulations company. We suggest going through a private company for this rather than the council who tend to be a bit slow when it comes to visits. You’ll need any relevant water permissions and a party wall agreement unless you are detached and surrounded on all sides by a little bit of land, a luxury most of us don’t have… This ‘paperwork’ as we call it is going to come in at around £5-9K mostly dependent on your chosen architect.
Then we get to work! You’re looking at about 3-5 months for a kitchen extension and ground floor remodel, in labour fees that
Then, once the place is built we have to deck it out. Many people fall into a bit of a trap here when their build is agreed to take them to ‘first fix’ only. First fix is when you get left with plastered walls ready and waiting to be painted, an empty room waiting for a kitchen, bathrooms to tile and plumb and doors to be hung. All of this also needs fitting, so more labour. This is why a first fix extension seems like such a good option for the balance books but in the
So with that in mind, we’re going to take this rough price gauge up to the ‘I can actually live in this stage’ or, 2nd Fix. You’ve got to buy your kitchen, hard to say a price for this as it’s so dependent and appliances but let’s give it a range of £4-10K. Then maybe a downstairs loo? £400-600 (assuming the plumbing and creation has already happened). Paint (we’ll go conservative and steer clear of the top shelf brands for now) approx £200-£300. Flooring, tiles, real wood or a wood effect laminate could range, again dependent on sq meterage anywhere from £1000-£4000. Bit of marble or Quartz for your worktop? Budget for about £3-5k.
Back bi-fold doors and roof windows will range from £6-8K and a lovely over Island light fitting about £400.
All in all, if we stick to the middle of these estimates you’re looking at an average cost of around £105,000 with your cheapest option, if you’re really thrifty, around £89K.
Then you have to start thinking about your furniture…..be sure to save some budget for that too, it’s the most fun!
