Hi All -

We moved last year to a bungelow - it's a 4 bed & on a decent sized plot, so good scope for future extension.

It would seem to have had a dorma squeezed into the original roofspace giving one upstairs room (a weird shape) of about 250 square foot.

Once we were in, we realised that there is very, very little insulation between the ceiling of the upstairs and the roof - such that as soon as the sun shines the temp in the upstairs gets to high 20s an over 30 in the height of summer. Naturally in the winter its an ice box.

Add to this that the roof leaks into our (downstairs) bedroom & we come to the conclusion that it clearly need to be re-done (rather than repaired & insulated)

We are contemplating trying to maximise the upstairs space (or to try to get over the additional 250 square floor that we currently have up there)

As funds are relatively restricted, current thought is to do it in two stages:

1) re-shape the roof space & insulate (possibly a mansard conversion) to create additional c. 500sqft of living space (this year)
2) fitting the stud walls plumbing and finishing to accomodate 2x beds & a bathroom up there (next year)

want to get a real beermat steer on what each stage is likely to cost & whether we're crazy to be thinking about doing it over two building phases - are there economies of scale in having one firm do the lot or would the main building work normally be carried of by separate firm to the fit and finish stuff?

would it cost, say £40k to do in one, but 25k each half? or are they way low?

Really don't have much of an idea as to what to expect - so any tales / experience of similar welcome.

Below are the floorplans as they currently are:

Cheers

ETA: (Bedroom 4 is above the dining area, all to the left of the chimneys)

We're in the process of reroofing our bungalow for upstairs living area (see my build thread). Depending on your area, your costs look reasonable. We've created about 70m2 space and the quote was £65k, which included everything from start to finish, including the fitting of two bathrooms (excl sanitaryware).
will follow your build thread with interest - looks very similar to what we are intending :-)

area-wise, we're in Surrey

Interesting floorplan, I think I'd be trying to work out what the future downstairs layout should be in conjunction with the upstairs. That looks awkward to me, bathroom by the front door and a bedroom off the lounge. Feels like it needs a bit of a re-org downstairs which might give a better location for the stairs to rise and serve multiple bedrooms (they current come up to the left hand gable wall right?)

Loads of potential there!
Yeah - the downstairs layout is a right mess! - though oddly - as we've lived in it, have got used to the quirks and foibles - the stairs do lead into the gable wall which then gives a cut off door to the upstairs....hardly ideal!

The bedroom off the lounge is the kids games room - though they rarely use it as its such a long way (relatively) from the kitchen.

Any good software that lets you play around with layouts/designs etc.?

Your layout is pretty much identical to mine.

Same footprint - yours is much more sensible layout! what was the 'before' like?

If you dont mind my asking - how much is the roof element of your works? (i'm guessing you are in the trade) looks very like what we're going to try to achieve.

Did you have to raise the roofline at all?

Before we started

40 degree pitch, plenty of headroom.

About 20 k in so far. Expect another 20 to finish.
is that for the loft, or for your full project?

ours is much more shallow angle (per the below), so i think we'll have to raise the roofline - which i guess means full planning....

how much square footage are you gaining in the upstairs?

40 k finished, but I have called in some serious favours.

Looks like you are not far off 40 degrees there, but you'll need to lose the hips on each end to gain space.

We've gained 75 M2 of floor area, that's without including eaves storage.
Sweet!

That why (new convert) bungelows rock! What does that work out as as cost per sq ft - about 50 quid?

Our ground floor 'footprint' is c. 1200 square foot - figure if we can get about 800 in the roof, it'll be enough for a couple of bedrooms and a bathroom.

all starting to look decidedly feasible :-)

I guess once we've had the drawings done, it becomes a slippery slope!

Whats the best order re- planning/drawings/refining etc.?

I remember a pal who was in the renovations business saying to 'over do' the initial plan on the basis that if rejected, your 'compromise' is more likely to be accepted - though that sounds very disingenuous.... (then again, this is the property world..... )

OK so here's the first draft floorplan that we've had done:

would be interested in any views on it, as once we kick it off ther'll be no going back!

Its basically a large box dormer on the rear but not over the existing extension. As such the 'room' to the right on the upstairs floorplan is not technically useable (doesn't bother us as we just wanted the three bedrooms upstairs.

We'd be losing the (wierd) downstairs bathroom to accomodate flipping the stairs to a more traditional form...

anyhows please let me know what you think and if we're missing any tricks on the layout.

(porch is likely to be added to avoid the front door leading straight through to the dining room)

You appear to be proposing a lot of bedroom space but not much bathroom space either in numbers of bathrooms (inc en-suite) or the m2. Is that the ratio that you were seeking?
Ah - yeah - should caveat that this is the first phase - to sort out the upstairs for our three kids (currently 3, 5 & 7)

In time, on the ground floor plan is to knock through the bedroom off the lounge into the kitchen and utility, together with using half the current lounge for an L-shaped kitchen/diner.

The two downstairs bedrooms will remain as is - but with an additional W/C in the front bedroom (bottom left) - to be a guest room.

your right - it is an odd layout, and difficult to envisage how its going to come together - hence after some advice!!

cheers all

Cheers - all good grist for the mill....

you've lost that odd room to the right, but who knows that that was for...
Well - the original building footprint didn't include the garage that has been converted (downstairs bedroom & loungue on the right of the floorplan), so under permitted development we can't go over the top of it.

big store room/man cave.

Do you really need six squeezed in bedrooms? Also a bedroom downstairs off the living room and a dining room in the stairwell/hallway aren't ideal.

If I'm honest I'd give your entire layout up and downstairs a rethink.
Sorry - bit unclear from the postings above -

the loft is being done first, as the kids are currently sharing the single upstairs room which is freezing cold in the winter and roasting in the summer

Master is staying downstairs (the rear left bedroom) with both this and the other downstairs bedrooms having en-suites (with a shower added to ours and a loo to the shower room in the front)

The room off the lounge isn't really a bedroom - so the plan is to knock this through the existing utility and other half of the Lounge to create an L shaped Kitchen/diner/lounge with the remainder of the lounge being left as a snug

Excuse the ham-fisted powerpoint alterations to plan the the ground floor will end up looking (roughtly) like this:

Living room too small and kitchen too big and odd shape.
Knock the bedroom, utility and kitchen into one big room.
Current thinking is along these lines (ignore the kitchen units - these were just from the initial floorplan:

We're going to leave the bathrooms/shower on the ground floor pretty much the same and just squeeze a w/c into the shower room of the front bedroom ('tis currenly just a sink and shower).

Whats also not show on the rough floorplan is that the w/c will be under the new staircase.

Put a bigger, common upstairs bathroom off the stair landing. Connect to kitchen plumbing below for much cheapness.
Thats a good shout - thanks

Only of you've got an svp in the kitchen, thinking about it. Can't flush a toilet into 54mm sink drains...

Unless you install a macerator, which might be an option for you.
there is (currenly) a toilet just to the left of the front door - not sure how vertical soil pipes need to be?
