137m2 new build house project

[Dan1983]

Evening all,

Thought I would start a thread now we have embarked on planning stages of our first new build.

currently have a 3 bed dorma bungalow with carport which we have lived in for approximately 9 years.

We fall within the national park so taking into account the +30% legislation we have been left with an allowable floor space of 137m2.

Started off a few years back with extension plans which went through planning, but after consideration costs were coming in at 190k so decided to leave it a few more years and save some pennies.

I started to trawl through Rightmove looking at floor plans on new build properties that would suit us best.

Main objective was house, children’s toy room, ok size kitchen and 4 beds.

This did prove tricky with only 137m2 but in the end I found a suitable floor plan which came in at 126m3 and asked the architect to come out either side to max out the floor space.

Very please with the basic layout, only disappointment was the the kitchen ended up at 3.750m rather than the aim of 4m wide.

This was due to siting the downstairs toilet under the stairs rather than to the left and eating into more of the study/ toy room

The build also includes 7X6m oak framed garage which will use electric roller shutter doors.

Roof tiles will be slate but brick undecided at this point, pc sum allows for good quality brick to be used, pc sum also used for kitchen and bathrooms but going along the lines of howdens/ Elliot’s type spec.

Looking to try and add some character with slightly lower ceilings and maybe false beams etc, overall theme is forest cottage/ farm house etc.

 

Current very compromised layout

New render and floor plans etc

From overview house will be more centred on the plot  allowing new drive to line up better with the front door.

At present heating is basic, downstairs UFH, rads on first floor, system boiler with pressurised cylinder as had enough of combis.

Drive way will be gravel to match surrounding houses.

Planned start date for build is end of July to tie in with school holidays.

Obviously now concerned about how covid-19 will pan out as we need to rent a property until this build is completed (est 7 months) end product turn key. 

Fingers crossed!

Looks good. Have you energy planned it yet as the walls look a bit thin for a very high level of insulation unless you are using Ph / Pu I suppose also have you gone for UFH and ASHP?

 

[Dan1983]

Hi Mike, 

No not energy planned it, as per post will be UFH on ground floor and rads upstairs, system boiler with pressurised cylinder.

Did consider ASHP but was adding too much money onto the build at this stage

Yes it is the old DHW (Domestic Hot Water) conundrum all over again in that once you choose how to heat and / or store heat for your DHW the ASHP either comes into or goes out of focus. We started with a plan to have a gas boiler, ran all the gas pipe under the slab and up into the plant room - the idea was to use the boiler would run the UFH but in the end, what with gas becoming something of a negative thing with global warming, we have chosen to go for sunamp (or similar) for DHW and the ASP for UFH. Cost is a little higher but we won't need any hot storage, which in our house with 400mm insulation, will be a problem and we can disconnect the gas completely. 

[Dan1983]

Yes I really liked the idea of ASHP, but became slightly concerned after reading the hot water side of things.

There are only 3 of us in the house but guess we use a fair bit of hot water as son and wife both like a bath!.

I was told it would add about 10k to the build, we are quite hard up to our budget at the moment so had to park the ASHP for now

Is this based off a persimmon home? Pretty sure we looked at one with this layout.

[Dan1983]

Think it may have been Miller

[Dan1983]

As an update we had to have an ecology survey due to being in the national park.

unfortunately lead to having to have disk/ dawn bat surveys which has identified x2 bats occasionally roosting under tiles.

Now on to see how much more ££££ we are going to be relieved of for a bat licence  

[Dan1983]

For update we have our pre build meeting tomorrow.

Bat licence was not too bad, we require x2 bat boxes in trees and roof vents in house and garage with breaches felt to allow bats in.

Budget to be finalised now SAP and building regs are complete.

Main change if budget allows would be an ASHP set up

Have you considered applying for or extending under PD and using the 30% on top of that as that would really help with your proposed new build floor area?

[Dan1983]

Evening, you cannot do that under national park as they take one or the other away from you to stop being able to extend more than 30%.
