Renovating Design Dilemma Kitchens

Awesome extension project

2 months ago

last modified: 2 months ago

Hi folks,

We are currently looking at putting in an offer on a house that we believe has potential for a superb rear extension. I'd like to gauge if what we are thinking is possible and get your views on potential costs and alternative ideas. Any folks out there that enjoy visualising this stuff, feel free to have a go!

The rear of the house has two basement rooms under the kitchen that go down to the same level as the rear lawn grass, seen in the first picture. There is a raised patio from the lawn level up to the kitchen level. We would like to extend out within permitted planning restrictions and remove the raised patio element, creating a beautiful double height, open plan kitchen and lounge area.

We could also add another phase to build in a garage and gym area. Existing garage would be lost in the rear extension project.

I've had a go at sharing my vision below, let me know your thoughts and ideas!

Do let me know if you have rough ideas on the value this would add to the house. Currently house is on the market for £1.4M and is 2511sq ft including garage.

There are a few super things about your ambition. I agree that you should be better connected with the garden and the total square footage seems small considering the size of the plot.

You need to work out your budget and that will dictate what size you can afford to build. For instance- say you have a £500k budget for the whole house you might well allocate £220k for new kitchen/heating/wiring/flooring/ exterior maintenance such as roof and paintwork. Since your plan involves demolishing a patio you will need another and could well be £45k. This means that there is about £235k for the build and with high ceilings you should probably be allocating £3k/metre square.

If it were my house I would have two basement bedrooms in the extension and then have the kitchen and other new rooms at the same level as the principal rooms., if they are not then likely the current principal rooms will become unused.

Thanks for the reply Jonathan. Good point on having principle rooms level with the extension. On the other hand, we quite like the idea of having a feature stairway beside the wine room glass frontage and the basement rooms are not quite full room height, so they would be tiny bedrooms. We'd also need to think about the access from the sitting room, so lots to ponder.

In terms of budget, the whole house has been redecorated recently and would only need a few carpets changed for better flooring and the rear bedroom windows changed out for modern metal frame windows. The spend would only really be needed on the extension, new kitchen and some structural amendments to the end of the existing dormy room to change it into a semi-outdoor space. I can see the roofing solution being quite high cost with the skylight idea.

Keep the ideas and comments coming!

Extensions take many different forms but, often make all the difference connecting inside living spaces to exterior gardens. Here are a few we have done recently: side and back extension... double height extension... Rear extension... roof top extension...

Hi there! I would strongly suggest that you first consider the local regulations. That way you will increase the likelihood of the plan being approved by your council's planning officer (assuming you require permits). Therefore, I would take a look at other similar extensions in your street, see how the shape of the roof would fit in with the existing roof and finally, check if the shape of the roof would make an impact on the neighbouring houses in terms of sunlight. If you need any further assistance - I would love to help you further. Check out our site for more details! betterspace.co Good luck, Udi

Help! Layout options for side and front extension, best use of space!

We are in the process of extending (a joint project with our neighbours to gain an extension to the front box room, then along the ground floor across the front and down the side of the house). We're having some last-minute layout dilemmas, the floor space isn't the biggest, but we will gain some essentials from it (bigger kitchen, downstairs shower/toilet, office space, porch and the bigger box room upstairs). Our shower room is going to be fairly slim (worked out as 900x2900mm at the minute). This also creates a slim corridor space beside that leading to an office which I've bumped along a bit to give some more space (sacrificing utility space at the other end, when you compare my Ikea layout with original drawings). The other option is to access the office from the lounge, meaning we could lose the corridor altogether and widen the shower room, but that would make the office open to noise from the lounge and I think it's a weird place to add a door. We're also struggling with options for the laundry/utility space too and whether to just include it as an extension to the kitchen. I've added some screenshots and links to an Ikea planner I used to map the ground floor out completely (ignore the colour and the basic mapping of furniture etc. it also doesn't include the pitched roof and Velux windows). Any input would be appreciated, I'm just looking for layout ideas and tips for anyone that has similar sizing/spacing set-ups. Thanks.

So what is your budget for building?

We dont have a budget yet. We’re scoping out the total cost vs future value of the home to judge how much we’d like to invest.

For anyone that enjoys a bit of photoshop, this is what we want to do with the archway windows which will obviously be longer down to lawn level

The kitchen extension would be something similar, forming a nice L shape with the arches in the current elongated part of the building:

To do this you will have to demolish the garage block and rebuild it a meter lower. It seems like a lot of expenditure for no gain in square footage.

But I can’t help thinking you have become focussed on building one amazing all purpose room and you are ignoring the rest of the house. I estimate that the extension is about 1.5m lower than the main house and this is a big enough difference for the entry level and the extension to be disconnected.

On reflection you might conclude you would rather have the inevitable change in levels on the patio rather than in the middle of the house.

You might also consider if the extension should include at least one more bedroom. At the £2m price point would buyers expect five bedrooms? Would they expect bigger bathrooms than this house has?

Just for my fun I have played with the plan. I concluded that if it were my house I would want a living room that is wider than the current reception rooms. I also felt that the first impressions could be improved if the hallway received extra light from the former kitchen (from the side) which in turn creates a more impressive hallway and allows valuable storage for coats, an opportunity to have a better guest WC than one under the stairs but mostly a better entry into the largest room in the house.

I put two lower level bedroom and a light well to the side.

And I felt that with a big roof outside the former master bedroom the only Ensuite bedroom could be improved so I took two bedrooms to make a master suite.
