New Bungalow extension in the UK help

Thats looking good Dadgad, would it work having the end wall with the doors and the new side wall facing down the drawing all glass ? I am thinking frameless full height glass it would put a lot of light into the kitchen/dining room if that could be done, I assume it would have to be a metal frame work to support the roof ? it would be like a built in Conservatory with a solid roof would be cooler in the summer ?

 

A bit like the attached photo

Glad you like it.

The arches on the two doors into the living room make for a little old world charm and admit more light.

If need be you could put a double pocket door between the kitchen and living room, or a pair of heavy curtains to close that opening when concerned about heating loss.

What happened to concern about heating costs?

This would certainly be a lot brighter, and the use of a sliding door effectively increases the useable floor space, I need to put the back door in though.

Structurally no problems whatsoever doing it.

Steel columns supporting the roof extension over the back patio would carry the roof load.

I enlarged the side window in the kitchen area, as with all the increased light from the back you don't want to be working in your own shadow all the time at the kitchen counters.

Being new work it would be simple to put in a steel beam as a lintel above full width/height end wall glazing. You'll probably need an engineer's calcs for that and you'd be better off with hinged rather than sliding doors.

As it's facing west you might like to consider how to control sunlight - my very limited UK experience is of a southfacing slate-roofed conservatory that gets *very* warm in summer. Extendng the roof or a slatted pergola over an external porch or pavement would assist.

Can't help much with the cost of drawing up plans for Council - IIRC it cost me $400 for a draftie to do so for a similar sized job 30 odd years ago and in retrospect it would have been far better to ask a builder for a quote to design and build as they prefer not to have to work to a set of approved mistakes such as the flat roof we tacked on out the back ...

The 2 meter roof overhang at the back would help a lot,

but a pergola would be a nice touch on the inside corner behind the living room,

and provide aesthetically pleasing sun protection on the short return wall.

Wouldn't cost much more to extend the overhang a couple more metres to endposts covering a paved portico set up for outdoor dining. Depends a lot on the sun angles and weather of course. It seems almost a requirement these days to set up a fancy BBQ and a dining setting for socialising that used to occur indoors. We're considering demolishing the garage to make room for this.

Our big mistake with the flat roofed extension was where it joined to the existing at a point similar to that between the two kitchen windows shown above. To preserve ceiling height the flat roof went into the existing above the gutter line and besides looking awful it needed extra downpipes to handle the interrupted guttering. A pitched roof over some gangnailed trusses to preserve the eaves line would have been better even with lightweight roofing. Fortunately we ripped it all off in a subsequent extension.

Hugha You can see that Dadgads roof over hangs close to 2mts I would guess, so that would/should help with cover for shade and dining outside out of the direct sun.

I am still waiting to see someone from the UK to say if having the roof over hang like that will affect planning laws as the extension can only be 3mts out any bigger requires planning permission , so if the roof counts as part of the 3mts then it would yes ?

A pergola was what we were thinking right across the lounge wall with grapes growing on it would be nice, we may even add a patio door my changing the window to the right of the lounge, we might in few uears time exden the fron to it is right across the property and then the front door would be facing the street not on the side as it is now, that would mean we can add a ensuite to bed room 2, it would mean changing the roof line so cant happen just yet.

Dadgad I went past the bungalow yesterday so I took a picture so you can see and it has a roof that is different then your plan at the front elevation, could you let me have your latest drawing DWG saved back to 2008 please, as I can only draw in 2D it will be good to show the wife a 3D version of what it might look like from all sides.

Of course being in Oz, you have to knock down the garage in order to provide access for the beer deliveries, and sides of beef for the barbie!

Sorry, just having a bit of fun, as barbecuing certainly is the norm in your neck of the woods, and I enjoy that (whenever I am down there).

Been a while since I was in the UK, but as I recall it, Melbourne's weather is a wee bit more barbecue friendly for much of the year.

But yeah, wouldn't cost much more, and a shed style roof would be my choice too over a flat one.

Still from a purely aesthetic perspective matching the existing roof would look the best, and maintain ceiling height.

Easy for ME to say, I am not the one who would be paying for it.

That is very helpful.

Based on your description of the existing roof I had assumed that the roof extended over the front corner, and that it was a covered porch.

Hey, isn't that a TILED roof?

As opposed to a felt one?

I will send it along in a few minutes.

Here it is saved as A 2010 file type.

In order to be able to work with this a bit, just go to the Autodesk website and download DWG TRUEVIEW 2012.

I made the windows conform more nearly to those in the photo, fixed the entry hall and roof shape and overhang, which is clearly not 500mm as I showed it before.

I can post it as a 2007 file, but better to use this one, as suggested.

Here it is as a 2007 file too.

Nice to see that you have what I take to be operable transom windows for ventilation up under the eaves.

Looks like concrete pantiles - should be easy to add to but they're heavy. By the age of the house I'm guessing its a prefab trussed roof with trusses running east2west so the lintel over the opening into the extension will need some thought and qualified calcs. No biggie. Just pick a fine day to install it.

No barbie today, it's full-blown winter, 14degC and bucketing down. I'd take the roof out to the maximum allowable. Can't see why council should oppose it as it's not some poor cottage out on the moors that you can't change for love nor money but if they charge big approval fees then I'd go for what you want within your rights. By the time you have a builder teed up the extra cost of material and time is quite minor compared to the overall project cost.

Looking at the photo reminds me the sun comes from the south - wouldn't your grapes prefer to be along the driveway rather than in the shade?

A pergola was what we were thinking right across the lounge wall with grapes growing on it would be nice.

Here you go.

I raised the height of the pergola deck by 500mm to give the grapes (once they get there) a little more light.

Thanks Dadgad nice one m8,and yes they are pantiles we dont use felt tiles over here apart from garden sheds they have felt on them. and yes they are top opening hinged windows

Yes hugha the sun is in the south so the garage side of the home has the sun all day

Lovely, would look good, but it's out to the northwest where its benefit is restricted to shading the loungeroom windows from summer afternoon sun. No matter, start the grapes off up the westernmost posts to get some light while they grow. Once they're at rail height they could get enough light to have a good go at the tiles which they will if you let them ... our grapes have clambered to the second story.

Dadgad something strange happened when I opened the drawing the glass wall is not as your picture it shoots off towards the pergola, and I can't scroll in on the picture it shoots off to the left or right for some reason is that a 2007 problem ?

That happened to me too, but I changed the visualstyle and it sorted itself right out, not sure why it happened.

What happens if you use the ORBIT command?

I just resaved that as 2007, and uploaded it to the previous post, try opening that one and see if

it works any better for you.

Remark ceiling heights are about 2.4mts, and yes in the UK walls and roof are well insulated, but we dont tend to over heat rooms the kitchen wouldnt be kept the same temp as the lounge and bed rooms would be cooler as well, we have gas condensing boilers and wet radiators with TRV (temp regulating valves) so each room is heated to the right temp so doors tend to be kept shut for that reason

If that's the case why not consider radiant heat in the new lounge area?

Do you really want to be growing grapes next to your house? I'd put a patio in that location with a retractable awning. I'd think you would get more use out of it.

Dadgad the glass wall is still off under the pergola and the walls are no longer filled in ?

Do a REGEN, enter REGEN at the commandline, hit ENTER.

That should take care of the window with a mind of its own.

Should that not fix it, then change the VISUALSTYLE and I believe that will.

I don't know why that happens, seems to be a bug.

To fill in the walls you want to change the visual style.

If you activate any VIEWPORT by double left clicking inside of it, or in MODELSPACE you should see

VIEWPORT CONTROLS in the upper left hand corner.

There are 3 of them there.

The right one controls the VISUALSTYLE, by choosing from that drop down menu you can explore the different display options available.

The middle one controls the perspective, you can choose from the 8 standard perspectives including the isometrics which will give you a 3D view.

You can also enter ORBIT at the commandline > ENTER .......and really take the model for a ride, so to speak, and look at it from any angle.

While in the ORBIT mode, right click and select PERSPECTIVE, as it will look better than the default parallel view.

Let me know how it goes.

ps. I reposted the drawing last evening, and put 4 viewports in paperspace showing 4 different views. Not sure if that is the one you are working with or not.

Regen didnt correct it and I am not seeing 4 viewports only 2 and double clicking in the viewport only brings up the 3d control in the right corner, please show me what your screen looks like so i can see what is different, it might be because I only have 2008 maybe?
