Project: Building an upstairs to our bungalow [pics]
Discussion
We have a bungalow which had already had part of the roof raised to fit a couple of bedrooms. Our project was to extend the roof-raising to the rest of the house, and to introduce half-height walls in order to remove the aggressive eaves and greatly increase the usable size of the rooms. We’re also changing a hip end to a gable end.
First pics are the plans:
Scaffolding starting to go up. Forgot to take a proper ‘before’ picture, so this is it.
Full tin hat scaffold up:
Small roof before its removed:
Small roof now removed:
Large hip roof ready to be removed:
Large hip roof gone, leaving front gable end looking rather lonely. Raised half-height wall structure now in place:
New trusses/rafters or whatever they’re called are now in place over the front half of the house, and new gable-end being formed.

New valley cut into existing roof. Note the new rafters are much bigger than the existing cutoff ones they’re attached to.
New rafters now installed over second (new) bedroom. Two holes for velux windows are present, along with a large gap to the right hand side where a dormer will go.
Note the additional height (c1m) we get from installing half-height walls compared to the original rafters which you can see cut off at the floor:
Two pics showing the large window in the gable overlooking our garden. Note that the central column in the middle of the window is temporary support and will be removed once a custom-built cranked flitch beam is made and fitted.
Reducing the pitch of the roof meant an alteration to fill in the existing gable end at the front of the property. Done with stud walling rather than block work.
New gable in place, following hip-to-gable conversion. This will house two bathrooms (one ensuite and one family).

Roof structure complete.
View facing the garden with large window:
View from the large window, towards front of house:
Dormer structure in place. This dormer was needed to increase headroom at the doorway to new room.
Dormer build furthered, and main celotex insulation installed between rafters:
Insulation lagging installed in floor voids.
Muchos CAT6 data cabling being installed. Now, where did each cable go again?!

Next update.
Roofing started. Weather sheet on and battens down.
Original tiles going back on the roof. Valley gutter put on. I would have preferred tile valley, but I missed that the architect's spec didnt request it. Not overly bothered though.
Hanging tiles on side elevation completed. Its quite some run at around 13m plus the height of the new gable in the middle.
Stud walling gone in, separating the new space into 2 rooms and 2 bathrooms. Makes everything look smaller!
Its ok, the builders ensured the house remained secure. No-one's getting in through that window!
All the celotex insulation in place; 75mm between rafters, 40mm over rafters. Looks like a spaceship!
Main gable feature window in place. Would have preferred not to have the central pane split up like that, but it was the only way to create an opening in the window without having to carve the panes into many more pieces.
Plasterboarding installed and tape&jointing started. Not going with plaster skim. Blue boards are acoustic insulating boards, which we put on all studwork. Within the studs I've gone with RockWool 75mm acoustic insulation slabs at 45kg/m3, so altogether should have good standard of noise insultation.

I don't think our conservatory has much of an impact, as it's just tacked on to the external walls. We have fully insulated external doors to it, and it's not heated by the regular central heating, so no heat loss. I never liked conservatories before we actually had one, but I really like it now. Even in the winter, all you need is the sun shining and it's almost I instantly warm enough to sit in (we're south facing). That said, I have thought about replacing with a proper orangery, and could even then build on top. But think it would add little to my practical enjoyment of the house, it'd just be empire building.
