Renovating Design Dilemma

Ground floor flat - Extension and change floor plan

3 years ago

last modified: 3 years ago

Hi all - I'm in the process of planning a ground floor extension for a terraced conversion that I've made an offer on in South London.

The property is in need of work throughout and my offer (and the agents valuation) reflects this. I've attached the current floor plan and my proposed floor plan below. This would add another bedroom to the property and give a nice open plan kitchen / living area. I'm slightly concerned about costs and, to the extent I cannot afford the below, I may need to keep the current layout but just refurbish kitchen / bathroom / replace front windows etc.

My total available budget is probably £100k - £120k and so I think that a side return extension with new kitchen etc should be possible but concerned that new front windows and reworking the floor plan at the front of the house (new partition walls / doors etc.) would make this unaffordable. The bathroom layout doesn't change and a new bathroom could wait in theory.

I think the spend would be worth it. It creates an extra bedroom and more living space which opens onto a nice big (relatively, for London) garden.

Any comments on proposed floor plan and potential costs / complications would be much appreciated. Slightly worried that if I commit to the side extension and builders costs are excessive / underestimated then I may run out of funds...

Thanks

Jamie

hi Jamie

For side return extension if that is your plan be ready with about 70k+VAT budget and another 10k in total for client supplied items.

that means you still have another 36k£ to spend on your project. as i haven seen your windows on a front i can just guess but i would say with 1 external door and 5 windows assume about 5k+VAT incl installation.

bathroom refurb can cost you around 5k+VAT and

refurbish of the whole ground floor about 15k+VAT incl new door liners couple of studwalls new plastering new skirtings and architreves etc.

for flooring and other stuff allocate about 8k+VAT and for profession fees another 4k+VAT.

i would say in total a bit tight but you can have all your list to be done.

just be sure you get more quotes in as builders are charging nowadays from a-z depends on there availability and flexibility.

have a good luck.

Hi there Will, This is a great project. I love the transformation of flats into open plan living/connecting to the garden. Your floor plan is huge and the final product would be fantastic. I have worked on over 600 residential developments and these are still my favourite. The extension costs will be in the region of £45-60k + VAT and generally clients would spend in the region of £100k + VAT on the redesigned space once they have purchased a kitchen and glazing products etc. At this stage it is almost impossible to determine a more accurate figure without a design being produced/specification finalised and further investigation works being carried out, hence the range. A few questions/pointers. Do you own the share of freehold or are you a leaseholder? When designing this, consider a small courtyard outside of the bedrooms to enable you to retain daylight filtration/ventilation. Have you analysed the market to see what the value of a 3 bedroom flat would be? Might be worth considering this as part of the design to maximise value, if you are interested in this. Note that the extension may need to be bigger, however if you end up spending an extra say £15-20k increasing the SQFT/gaining a bedroom, then this could be a sound investment. Happy to assist if you have any further questions. Nick

Thanks Jonathan, Really appreciate that and gives us some food for thought. Unfortunately I don't think it would give us the size bathroom we would like (hoping to keep it to as similar size to what it is now. We'd also prefer a window for ventilation due to condensation in the property. I think it's probably more difficult that I thought to ask someone to do this without seeing the property due to it's 'quirks.' The cupboard housing the meters is bigger than the plan properly shows for example (approx 60x60cm), and there are 2 steps going down into the kitchen. If it makes any difference to anyones thoughts the wall between the bedroom and reception room is plasterboard and so could be changed easily. Would really appreciate any further thoughts though...

Hi Saskia, Depending on your budget & site conditions you could build a very small light weight extention to serve as main entrance lobby. This will create a separate entrance without shrinking the existing reception. Regarding the glass to the other bedroom it all makes sense. Your utility cupboard could stay against the wall, flush with your new kitchen, which would move where the small bedroom is (I assume this is your plan for now). We've designed something very similar not long ago, please see link below. The project is currently under construction and will be finished at the end of June. https://www.houzz.co.uk/hznb/projects/victorian-house-rear-and-loft-extension-pj-vj~6159497 We would be happy to assist further with the design, please don't hesitate to contact us.

Thank you for everyone's help with this, Jonathan great idea - I was thinking of potentially moving the kitchen to the bedroom area, to give a great living space, with French doors onto the garden. If I did go for the extension with the side, I was hoping it would be a bigger enough space that I could make the flat a 2-bed. Something like this - but not sure if living space will be comprised. I would personally have the front room as a lounge but could sell as 2-bed?
