Drainage Plans - Developer Not Playing Ball

You would think such people would know what an ellipsis looked like...
Here's a good example of what the OP is trying to say.....

That's a recent development that i dealt with. All of the plots have visible 'drain covers' for inspection into both the foul and surface water drainage before they reach the main road some on lawns, some in gravel and in one plot, on the earth where it hasn't been finished getting landscaped. By building regulation standards any manholes have to be located within the plot boundary so its quite frankly impossible for there to be no visible 'drain / drain covers' in his own house plot without the developer being breach of the regulations.
Are those houses built like that in case of flooding , looks weird having the door 2 foot higher than the ground.
Maybe you missed what the other guy said.
They're a minimum of 450 mm above ground level for the suspended floor. However, due to the contours of the site some of the houses are a bit bigger.
So have they all been built on the cheap or something? Half the gardens have the lawns looking a bit naff because of these inspection covers being fitted in the middle of the grass, they've all got the front doors raised and they seem to have these white lines down the sides of the exterior walls - like someone has put them together with a kit - presumably there wasn't much bricklaying involved!
Hardly cheap. The inspection cover locations will be the most direct route from the foul drainage within the house. Thats more a cost saving than anything else. As mentioned before the raised door is for a timber floor as its for ventilating the subfloor. And the white lines are movement joints. Required for stopping your render falling off in large chunks. But it is built with a timber kit inside as thats how they build houses up here. Any other questions?
yeah, why are other builders able to manage to build houses with wooden floors without a ramp up to the front door? 
Isn't meant to insult you personally but those white lines/movement joints and this idea of a timber kit rather than brick laying does sound like a cheaper option.

Is that not the normal way to build houses? External walls are built from blocks to support the roof and internal walls are wood.

They don't built to NHBC Standards
Building regs require min 150 mm sub floor ventilation, NHBC require 250 mm so they will sit higher up.
In Scotland, timber frame is the 'standard' construction with Englandshire using masonry cavity. The movement joints are required because of differential settlement meaning, timber frames settle more than the blockwork and at a different rate.
Touch, the external blockwork is non loadbearing, all the structure is supported by the timber frame. However, the blockwork is tied to the timber frame to give a wider 'effective wall thickness'
EDIT
Also the ramps are required for accessibility for folk in wheelchairs
Eurgh, these are naff looking properties...cringing at those joint locations! Not even discrete!
p.s. to whom suggested soakaways, they don't work anywhere. They need the ground to be permeable, so anywhere clayey is virtually impossible to get them approved or work even.

you're the expert here, I don't work in the building trade, but are you really saying that all new builds that don't have a big step up to the front door or a ramp are basically not adhering to NHBC standards? Are they not able to just dig deeper foundations and incorporate the sub floor ventilation below ground level with vents suitably positioned or something? Because I've seen plenty of new builds this side of the border and none of them seemed to need to be raised off the ground like that or have inspection covers ruining the front lawn, thus I supposed these houses were done on the cheap.
Telescopic vents allow the floor to sit lower. They havent invented them up in Scotland yet
I would guess if they built the subfloor below ground level there would be issues with water ingress...
In terms of the covers, I can tell you that the house shown, you go in the front door, lounge on the right, bedroom left front and back, bathroom straight ahead with the kitchen at the back right. The drainage run will simply go through the under the house back to front and onto the mains. Hence the central location on the grass.

As above, due to any excess water we'd rather have a bit of cushion before any water gets inside the subfloor. Whats the point in having a damp proof course when you've got a periscope vent below it which will allow water to flood in

Other houses I've done listed here

If its in a flood plain thats fair enough, but periscope vents don't usually allow water to flood your floor void...As above, due to any excess water we'd rather have a bit of cushion before any water gets inside the subfloor.

sorry to jump in but usually the covers lift off but the surrounds should be screwed or bolted down to the concrete bed of the drain. You must have drains for your waste and rain water and sometimes toilet, sink and waste depending on how strict your region is.
You are entitled to know this as any fault with the drains on your property is at YOUR expense.
Ask PERSIMMONS to supply you with the water and drainage schematics for your property.
