« In Marie-Line’s kitchen garden, 

the plant growing programme 

aims to maximise the growing 

potential of the area available 

for cultivation and to disturb 

the soil as little as possible by 

using permanent terraces and 

minimise weeding by mulching– 

and all of this without using 

machinery. To carry out this 

ambitious programme Nicolas 

and Marie-Line decided to use 

mobile green houses.

Today these structures have 

yielded their fruit through their 

growing potential (extending the 

seasons and also getting an early 

start, crop rotation, the ease with 

which the green house scan be 

moved and the resting of the 

land by planting green manures).

From a technical point of view 

their green houses are mainly 

self-built. They are mounted on 

rails (on concrete foundations), 

they have a choice of three 

siting positions and each one 

measures 15m long by 6.5 to 

9.2m wide.»

«Recycled materials were used 

throughout (except the nuts 

and bolts and the sheeting) 

for this little green house 

whose construction design was 

improvised on-site. Pallets joined 

together by planks make up the 

side walls, onto which 8 small 

trusses are fixed.

The pallets were cut out with a 

saw on the outside to allow light 

to reach plants placed on the 

ground surface.

In all, 4 days work was all it took 

to put the structure together 

(2 to 6 people working on the 

site), from the initial idea about 

the way to build the tables to 

completion (excluding the time 

it took to source the building 

materials).»

«When it comes to self-built 

driers, here is an efficient and 

well thought out example ; not 

surprising given the 5 years of 

work to gradually improve the 

concept and a huge amount of 

preliminary research.

The whole system depends on 

the optimal control of vented 

hot air passing through heating 

elements and distributed 

throughout the five driers. 

In this way solar drying and 

thermal inertia work together 

thanks to a heat store of stones 

placed beneath each drier. 

Furthermore, the icing on the 

cake is the fact that in hot 

weather the heating circuit never 

exceeds a temperature of 25 

degrees C.»

«Here we are concerned with 

the extension and renovation 

of a storage facility for loose 

hay. Recently carried out for 

the farmers, the renovation of 

the building mainly consisted in 

the installation of a mechanical 

(and telescopic) hoist. To install 

this tool the strengthening of 

the existing roof was necessary 

(replacing the trellis truss with 

a glue laminated collar beam). 

Two RSJs could then be installed, 

which served as the rails for the 

hoist. The entire refurbishment 

was self-build.»

«These totally self-built 

structures were designed to be 

as mobile as possible : in static 

mode the hen house rests on 

the ground and when it is being 

towed the specially welded axles 

are placed underneath it and 

the structure is attached to the 

tractor. In around ten minutes, 

the job is done and the hen 

house can be moved to pastures 

new whilst leaving all the chicken 

manure behind it on the soil.»

 :

« From the quality of the design 

(challenging and masterly) to the 

speed of construction over just a 

few months, this building could 

not have been seen the light of 

day without considerable prior 

self-build experience.

In parallel with his new 

venture as a farmer-baker, 

Pierre has built an impressive 

new agricultural building, 

incorporating all the facilities 

necessary to the launch of his 

new activities.

This L shaped building fulfils 

several functions : a separation 

of the barn/storage area from 

the processing/ bakery area, 

whilst managing to connect 

these areas with an outer yard. 

In the shape the building has 

taken, each space corresponds 

with a production stage in the 

work, is accessible from outside 

and benefits from good natural 

light (apart form the storage 

area which required less light). 

The ergonomics of the building 

are reinforced by the proximity 

of the different areas, and 

the ground floor layout (on 

an extensive concrete screed) 

facilitates all movement and 

transport.»

 :

«As regards construction, the 

structural elements were made 

of frames made out of tree 

trunks, prepared by Pierre using 

a chainsaw and assembled 

on-site. A crane, purchased 

second hand, was used to lift 

the timbers from where they 

were stored nearby over to the 

concrete screed ; the frames 

were lined out respecting the 

marking out of the screed, then 

they were erected and secured 

to the concrete plinths. Each 

frame took about 6 hours to put 

in place, without any additional 

help.

A light shuttering of planks on 

the elevations made the building 

weather-proof. The areas 

dedicated to the bakery were 

built from stud work.

Finally, the main work on the 

barn was finished within 4 

months, with very little outside 

help and a price per sq meter 

difficult to beat.»

«This extensive green house was 

divided into two parts following 

the sale of part of the land it 

occupied : one part remained 

with the farm and the other was 

sold to make allotment gardens 

for nearby properties. The farm 

part retained its half of the green 

house whilst the other half 

was dismantled. This situation 

provided the impulse for the 

construction of the dwelling. 

Prior to the dismantling of half 

the green house, a partition wall 

was built between the part of the 

green house to be retained and 

the part due to be dismantled. 

This wall looked as if it had 

always been there and formed 

the first wall of the house.

Subsequently a dwelling was 

built on a very small budget 

from recycled materials, sand/

lime rendered straw bale walls, 

polytunnel sheeting to keep 

the rain out, the recycling of 

refractory bricks, a carbon filter 

for a water supply from a bore 

hole.»

«This 60sq meter building now 

has a twin vocation : farm shop 

and potato store. It has an 

interesting history : its owners 

were not only self-builders but 

also recyclers. And they started 

from a basic observation, they 

had plot of land which needed 

levelling and which had poplar 

trees on it. From this everything 

else followed. The farmers 

brought in a mobile sawmill, 

had a small screed laid and 

erected the building. A few years 

later they had a stroke of luck, 

they obtained a lorry load of 

polystyrene insulation panels for 

ver little, which meant they could 

close the building and insulate it 

on the outside.»
