Is this a fair quote for a porch build?

OK, Ive just reworked the plan, this time the proportions are fairly correct (give-or-take 10 or 20cm):


Visual mockup (obviously proportions are completely wrong, but it helps me visualise how it may look):


Its south facing. So Im thinking - in summer - the french doors can be opened fully. Each french door will be standard door width, so I can easily gain access without having to open both doors.

Im thinking about getting a combination toilet/basin. Good for space saving. Something like: https://www.tapwarehouse.com/p/dylan-1100-combination-vanity-unit-anthracite-bv

I think clearance it ok for the toilet/basin. (Toilet needs 60cm front space, 20cm side gaps; basin requires 60cm frontal clearance).

Ive decided to go with a normal swing door for the WC. Also clear glass for the WC window. I like the idea of a wooden Venetian blind instead.

Does this all look ok? Any improvements or things I should change? 

Thanks

I'm not sure this will save you any space vs a conventional (slimline cistern) toilet and basin.  The basin looks much larger than you really need, plus the overall cost (after the 52% discount) is probably about double the cost of a conventional toilet/basin package.  Maybe worth the extra if you like the design and you want the additional storage space, but I don't see how paying more will save you space.

In terms of overall design, the front being mainly glass, and with French doors, there won't be much in the way of 'structure' to support the wall plate which will be needed for the rafters to sit on.  You'll need some form of lintel over the doors and windows to take the roof load.  This, plus the eaves detail, will increase the height of the roof along the front (compared to your mockup image) - so you'll need to check that the height of the modified design isn't increased vs what you have planning consent for.

I know you said you've decided on a swing door, but I'd taken a photo, so here's our pocket door to the ensuite. It slides into the wall on the left, which is essentially plasterboard on either side of the supplied frame, and it has 'brushes' along the side and top edges which fill the gap and stop the door rattling in the frame.

I'd have to have the top of the new roof joining at the same height as the top of your stonework, or it would really annoy me! I'd also be looking at the level of the bottom of the windows, compared to the bottoms of the windows in the side elevation. Would need to be exactly the same, or very different. Close but not exact, would also annoy me.

@Slinky: Wow - your door does look very nice! Ill have a further think about this.

@Section62: Yes, good point regards support. I will ask the builder for his thoughts. If I need to have more of a traditional door rather than french doors, and/or more 'structure' and less 'window', then so be it.

The builder mentioned that the work could be done on Building Notice Application rather than Full Plans. 

Do you think I should contact Local Authority Buidling Control (in my case Devon Building Control) or a company like London Building Control? (my builder recommended London Building Control for a dartmoor job he did last year)

It's a Howden's Holdenby door in an Eclisse pocket door kit.

Hi all. Things are progressing well. Im seeing the builder next week for a chat. He said hes happy to do the work as Building Notice Application rather than Full Plans. As I may have mentioned, he's used to building fancy extensions, so my humble extension is well within his comfort zone.

Something I havnt considered is heating for the WC. Its barely going to be used, but I do want something to prevent it freezing in winter. What would you suggest? Perhaps a simple heater plugged into a wall socket which  has a thermostat so it prevents freezing? Or maybe a heat mat of some sort?

A towel rail operating from the central heating (if there is convenient pipework to tap into) would probably work OK.  If no wet central heating then a small tubular heater is likely to be suitable for frost protection.

Hi all,

Progress is being made.

To help with the build, the builder has produced these.

Do these look ok? IE: The gap between the roof and the chimney stack, possible cause for future damp issues? Should the doors open outwards or inwards?

Thanks
