Don’t forget to make sure the DPM is continuous between the two floor levels.

@lgc……….or you could extend……

Would look nice in green.

It really is a pain in the arse when someone calls our office for an inspection and when I get there the concrete foundations have been poured. We just shrug our shoulders and tell them to employ a structural engineer to confirm that the ground is suitable to take the load. That normally focuses the mind and I usually don’t have to remind someone of their statutory obligation to allow BC to inspect the works.

If your glazing is greater than 25% of the floor area this will impact the SAP.

Only new builds need a SAP. Your conversion build would have had to comply with the Standards Based Approach for energy conservation. Other approaches are suitable including using SAP to demonstrate this.

What planet is your step dad on? Are you sure he was an architect? Stop work now before you spend too much money - you are building at risk and BC will ask you to remove or make good works that do not comply - including insulation standards. Hire someone to do your BC submission drawings and get a SAP done now. Things have definitely changed in relation to insulation standards/airtightness/renewable energy sources/pv and you need to get this right before you go too far.

Question 1: do you think we're f***ed, or is the £3,500sqm figure nuts? Question 2: would you be livid if your architect designed something double your budget without highlighting the rising cost? Question 3: do you think the doubling of stage 4 fees is reasonable or are they taking the piss? Question 4: anyone ever switched architect between planning and technical design? You need to sit down with your architect and ask them why fees have increased and why they believe the build cost could increase. If you gave them a budget they should have stuck with it - if materials cost have increased significantly between now and the appointment then you should be told about this and given the opportunity of either agreeing the increased budget or reducing the materials specifications - even the option to phase the works until you can raise the additional capitol.

Lidl had one for £69.99 recently.

Is this a top floor or intermediate floor flat? However I’d say that you’re flogging a dead horse unless you can find out exactly where the floor slabs or roof supports are located. Another thing you need to consider is the creation of a bedroom accessed from a kitchen and opening everything up - the rooms become inner rooms and will need an alternative means of escape and I suspect the existing corridor is a protected corridor - are the existing doors to the bedrooms and existing living room fire doors? However, Building Control should have the original structural floor plans.

Vent is a larder or what was a larder. Damp getting in at either the door jamb or lintel.

Emergency Egress Window.

No trickle vents for a start.

@Berkshire_selfbuildNo problem. Anytime.

Leave it as it is but put doors from each bedroom into a single rear en-suite to be shared by both bedrooms.

@NandM

Looks great. Love to see the floor plans.

Do not use PIR or polystyrene in an intermediate floor above a garage. You will not get the fire resistance you need. Speak to your local Gypsum rep who will give you a specification for a floor build up that gives you the fire resistance and good thermal resistance.

That won’t cure anything. Just hides the problem.

Vent tiles are no good for a roof where the insulation is placed between the rafters - the tile vent will only vent the space that it has been installed in. You should have had a continuous eaves ventilator installed. You really should have ventilated the ridge as well.
