I would be very grateful if someone could give me any input on the below property which my wife and I have viewed recently. We like it, however the layout upstairs is very poor, there is no en suite and the bedrooms are funny shapes. All due to the strange shape extension.

Very loosely, what kind of money would it cost to get the rear extension to go all the way up so we could increase the room sizes and but in an additional bathroom? Or, any other solutions..?

Wow that's one ugly extension.

There could be a lot of reasons why someone built that. Planning restrictions could be one. Altering it would require Planning Consent as Permitted Development rights will have [probably] be used on that hideous thing. You'll have to do a lot of opening up to check structural details before trying to adapt it to be a 'full height' extension.

As for costs well I'd BUDGET £55k to knock it down and start again. BUDGET £50k to adapt it. Those should include for gaining Stautory Consents.

Has anyone else on the street done a full height extension?

How about a loft conversion instead?

How about moving the bathroom into the 'internal' odd shaped bedroom. Square off the landing with new doors into the old bathroom and back bedroom. The split the new bathroom and have and en-suite off either the front or rear bedrooms?

Costs vary depending on location.

Take the photos and speak to the Planners first! They might be able to give you an informal indication.

If they do allow you to go 2 storey the full width then the front small bedroom could become an En Suite.

The larger Bedroom at the back will become longer and the existing bathroom could be made slighty bigger over the Kitchen with the possiblity of squeezing in another En Suit!

You would loose a Bedroom in that process though!

As the roof is hipped on all 4 sides you wouldn't gain a great deal of space up there. Plus you will need to look at how to configure the stairs leading up to the loft.

But if you get the 2 storey extension then you will obviously gain more space up there. Just make sure you bear that in mind in the design process. You don't have to do it all at the same time but if its designed in a certain way it will be easier to get up to the loft as and when you wanted to or funds allow!

I would imagine this property started life as a generic 1930's 3 bed/1 bath.

As a cost effective space enhancer, the current owners have whacked a dormer on the back and "nicked" the entrance to the back bedroom by fashioning in a partition wall through the original "back" bedroom (the internal one now). This solution would have been the most cost effective at the time to create the extra bedroom.

I would hazard a guess at approx. £50-60k to change the dormer into a proper 1st floor extension from what it is now (this will obv. be dependant on location and other variables).

I can't help thinking that throwing that sort of money at the place will only gain you another ensuite and possibly a larger, better shaped back bedroom, but with the possible loss of the small front bedrooom.

To do a proper "full" double height extention will most def. put you into 6 figure costings (location dependant), but will gain you a larger kitchen/possible utility/extra bed/ensuite and a better balance of space, but this will obv. be subj. to you gaining all the necessary planning.

It's a nice looking, well built house, but you may do better spending the extra money you'd spend extending it on a bigger house in the first place?
