New Project - 1980's House Update
Posted 24 June 2015 - 12:45 PM
The house in question was built in 1980, its an upside down house currently with 2 beds, lounge, diner and 2 bathrooms upstairs, downstairs has a further two beds, utility, bathroom, gym, sauna and Jacuzzi room!.
To the front of the house it appears to be a bungalow as there is a substantial raised deck (build with breeze block, steels and a natural stone shell outside) this has under it an undercroft with about 7ft of head height.
The undercroft blocks light from a couple of rooms and prevents any light from accessing a couple more, making the house very dark downstairs.
We plan to heavily remodel the deck, its currently 9m * 4.5m. We'd like reduce the size to much more like 2m * 5m and with an end extension on the garage of about 3m * 4m. Given that this would all comfortably fall within the current outline of the undercroft (currently holding tools, oil tank and coal) can we do this under permitted development?
This would lose the sauna / jacuzzi and gym but create us an open plan kitchen diner of about 6m * 6m. leaving us downstairs with much more light, two bedrooms, utility and bathroom & the kitchen diner.
We'd like to think about possibly adding underfloor heating downstairs as the slab feels very cold (the house has been empty for 7 yrs..) will we need to add insulation to the slab? Is it as easy as just laying some boards (of something? then adding pipes and screeding? can it be done in timber?
Presumably just getting some natural light in will bring up the temperature!

If you can find a way to showing a plan and elevations I think we'd have a better chance of trying to offer some suggestions, as I'm struggling a bit to visualise the house.
From what you say, it sounds like the work may well be PD, but could need building regs approval. You definitely need insulation under UFH, more so than for any other type of heating. Houses from this period rarely have any floor or wall insulation at all, and probably only minimal levels of loft/roof insulation, so that would all need to be looked at to see if UFH could deliver enough heat for the house.
This sounds like an interesting project, though, with what would seem to be a lot of potential.

The workshop extension would be circa 3*4m with a deck on top. We'd need to knock through the front wall of the existing and add a steel to support it. So that's about 10m of wall to be built in block and rendered. Then about 12sqm of flat roof strong enough to take the deck.
The kitchen extension would be circa 6*2m requiring about 4m of new walls and a lintel between. Then circa 12 sqm of roof strong enough to be a deck.
Our previous house had a plastic membrane roof for this and a conventional wooden deck resting on it. We are thinking of doing this instead of the current stone! deck
So for a shell we need as I see it 4 lintels (garage door, bi folds, kitchen knock through and garage knock through) + 14m of walls putting up, 24sqm slab + 24 sqm flat roof with a deck on it.
I'm excluding all internal fittings, roof lights, doors from this estimate.
What's the thoughts? Does 1000sqm fit? Seems like it could be high given that it's half garage build.

Will fit bi folds and Garage door ourselves.
Costings for the internal fit out are sorted

All I would say about a living room upstairs, and kitchen / diner downstairs is you will rapidly get fed up going downstairs to get a cup of tea. There's a house like this near me and their solution was a small bar area upstairs with a kitchen sink where they could make drinks both alcoholic and non alcoholic, including a fridge to keep milk and other drinks cool and a kettle etc.
If you are planning the ground works do you have or are you intending to buy a digger. There are a few of us on here that have done that.

I agree with Dave about the desirability of having some form of kitchen on the same floor as the living area. A friend has a 1980's split level with the kitchen downstairs and it is a real nuisance.
Cost-wise I'd price up the glazing to start with, as that's going to be costly and will also dictate the insulation level you will need to put in the rest of the building (you can trade losses from lots of glazing with additional insulation in the walls and roof.
I think I'd also cost in a cooling system, as if some of those large areas of glass get a bit of sun, and if the house only has modest insulation levels, it may well get pretty hot, especially with the living rooms on the upper floor.

I'll be on the train for 5 hours later today so I'll try and model the insulation.
For reference it faces East and is surrounded by trees on the other faces
