On

the

outside,

the

roof

is

covered

with

mud

and

grass.

This

obscures

much

of

the

house,

which

was

a

deliberate

attempt

by

the

owner

to

reduce

the

visual

impact

on

the

environment.

The

floor,

walls

and

roof

of

the

house

are

lined

with

bales

of

straw.

This

is

a

very

effective

technique

for

insulating

the

house,

particularly

against

the

cold

temperatures

of

the

Welsh

winter.

Lime

plaster

has

been

used

on

the

interior

walls.

This

product

can

be

manufactured

using

less

energy

compared

to

cement,

so

it

was

a

sensible

option

to

use

in

this

part

of

the

house.

Recycled

wood

has

been

used

for

the

floors

and

some

of

the

other

fittings

included

in

the

house.

Many

items,

such

as

the

windows,

a

wood

burner,

pipes

for

plumbing,

and

wiring

were

located

in

rubbish

piles

and

adapted

so

they

could

be

reused.

Fuel

for

the

wood

burner

is

available

in

the

nearby

woodland

area

and

is

recognised

as

a

renewable

resource.
