Brilliant project. Come a long way since we saw that corpse and the buried hand!

Still on budget?

This one ..... 

[Varche]

Thats it still makes us laugh now. Many a time I have felt like having an extended nap after renovations work. Still not sure about the hand. Need Silent Witness crew on that one.

Looking good Mark. 

Did you manage to place the internal steel so that the ceiling joists sit inside the steel to maintain a single level ceiling? If so, was there much/any disruption to the room above when you trimmed the joists?
I'm waiting for the structural engineer to do my calculations but at the moment it looks like I'll need supporting piers with pads. I would have preferred pad stones built in like yours to maintain the room width, or goal post steels to minimise the loss of a straight wall for kitchen design but will have to see what he comes up with. 

In my case the ceiling/floor joists sit on top of the steel, this I did because of two reasons:

• The room which is currently the kitchen will be opened up and combined with the adjacent room to be a large dining are (or snug as I keep calling it!), as a result I needed to keep the sight lines created by the lintels for the opening to the kitchen and the existing patio doors in line.
• The existing area is a flat ceiling (room above) and the new kitchen a vaulted ceiling so there was no major benefit to creating a flush opening

Now being somebody who always over analyses things, I did consider the joist into the lintel approach, my plan of works was:

1) Remove brick work to sides, enough to allow installation of padstones without impacting structure
2) Remove 500mm of ceiling plasterboard to expose joist ends
3) Support internal floor joists with props/boards and external walls with props/strongboys
4) Remove external wall to height required for external lintel
5) Remove block work between joists on inner skin and one row below
6) Shorten joists and trim top and bottom as required to allow fit inside web of steel
7) Fit half height noggins between joists
Install inner lintel, mortar top side to mate with inner leaf and jack into position
9) Point mortar bed and pack ends between padstones with slate and 3:1 mortar mix.
10) Pack as/if required between base of ceiling joists and lintel lower horizontal section
11) Install external lintel. 

The above is straight from the notes I made at the time so would need some refinement but is the basis of it, another option I considered was cutting the joists shorter and using joist hangers over the top of the steel to avoid all the faff of trimming.

£2k over due to scope creep.......she creeped and insisted that I upgrade the whole downstairs floor to UFH!

I am extremely glad that I put wet underfloor heating in the extension (and 2/3 of the existing ground floor).

I wasn't so glad during the build when I was digging up the old concrete floors though.......

Thanks for the feedback. 
I can fully understand what you mean regarding the sight line as yours is an extension of the whole house, whereas mine is just a kitchen extension, hence my need for a single level ceiling. 

Hmmm, UFH is something I'd not thought about.  It won't be so cold on her back when we christen it.

If your going for a screed floor its worth while in my view, plenty of options for supply out there to.

Some further progress all be it a weekend of catching up with smaller jobs and finishing bits off which seems to take a real age to do.

Saturday involved a trip to the hire show to return the Acrows and Strongboys before heading off to Jayplas (highly recommended for plastic in Nottingham!) to pick up some trims and silicon (£12 for 10m of 90mm trim plus some tubes of silicon).

So one broken brick to replace (I got a bit keen with the SDS when fitting the door) followed by the returns on the fascia, the trims around the triangular window and the separator trim between the window and door. All left to dry and then silicone in on Sunday.



I also did a stack of work preparing the DPM around the knock through areas to integrate it with the existing setup in the original house plus, drilling four holes and lining them with overflow pipe to pass the UFH pipes through.

Throw in a bit of pointing and shaped blocks to close the steel ends and another full weekend.

Pictured like that you get to appreciate the sheer scale of the extension. That will make one hell of a difference to your living space. 

Make it nice and cosy, as when your children start bringing their girlfriends/boyfriends home, that's where you'll be sitting.

Yes, that definitely helps to whittle it down to the genuine contenders.

The right hand 2/3rds (for the left of the Bi-fold across to the right wall) is the Man cave, Tv, sofa , games console, surround setup etc.....I fear it may be harder to get the kids out of there

Today is the first time I have looked at the before/after side by side:

[aaronjb]

That's probably what, an extra 40% downstairs?

Impressive work, Mark, your attention to detail is quite clear!

[Gaffers]

Looking good
