Victorian Terraced House Extension

[jdw1234]

Chaps,

I am thinking of putting an offer in on a house (in SW London).

However, I would be buying with the view to extending before moving in (to be our family home, not development).

Does anyone have a ballpark idea how much it would cost to convert the existing floorplan...



Into this (my rough attempt with microsoft paint)...



Externally, the house looks like this...



Here is a side plan of a similar conversion the neighbours did...



Many, many thanks in advance for any help received.

Depending on kitchen & finishing:

- downstairs £80k
- loft £50k

If you go for higher end flooring, kitchen, bathroom etc then add another 25 - 50%

You've probably thought about this, but I think you're a bit short of bathrooms / toilets!

Oh - and it's not in the Kew / Richmond area is it?

Can you build right up to the boundary? I thought there had to be a 3ft gap.

Sorry, I am an idiot.

The back bedroom on floor 1 would be converted into a bathroom - I didn't change label!

Also, would like to fit a downstairs loo somewhere (under the stairs?). Would need an architects advice as don't fancy watching Dancing on Ice to the sound of someone curling one out over my shoulder ;-)

Not sure.

Other people in the street have - maybe it is treated like a terrace or something?

You esentially lose your side access to the back garden.

Yep, near Richmond.

You need a redesign on the ground floor to provide an fire protected route from the bottom of the stairs to a final exit .

It cannot discharge into a room once you add a another storey

Cheers for heads up!

I need an architect, but was just after a ball park price to see if worth exploring.

Thanks again.

Give me a shout if you need any help, I'm an architect based just down the road.

Yes you can build up to the boundary however you'd need full Planning Consent for your proposals as your PD rights don't allow to in-fill the (in this case) small section of rear extension that sits behind the side extension.

Currently managing a similar conversion near Sheen Road. Three bed house to four bed (plus box room). One bathroom and two shower rooms. Full strip out, rear extension, loft conversion (making three storey in total), new windows and doors and new everything (wiring, plumbing, media etc..). Total price looking to come in around £180,000.00 when all said and done - ie; inc Party Wall, Building Control, Planning, Structural design and my design.




Terrible spelling tonight!

Not sure what's up with my grammar this evening. Terrible.

If you'd like a more concise breakdown of what's been spent where then drop me an e-mail. I'll happily give you a proper over view.

Thankyou so much for the helpful replies.

I shall send messages as appropriate.

Kind regards!

I have just completed a side return extension. The size was 3m x 8m. Including the obligatory bifold doors and a decent finish I didn't have much change out of £50K. The actual build itself was £33K
