Designers Guy Martin and Tino Rawnsley have combined their skills to create EOLIS  - 
a new concept of sectional building.

EOLIS offers an elegant solution in building design that can answer a wide range of needs  -  studio, office, retreat; a space for work, leisure and play.

EOLIS comes in a variety of different modules, which are fully lined, insulated and capable of rapid assembly. Its ‘bow-form’ ribs make it strong, lightweight and uniquely adaptable.

EOLIS is a light, airy, highly energy-efficient space which, because of its portable nature, with little or no need for foundations, minimises planning constraints.

All materials, including the lining and insulation, are local and renewable, and the timber is fully FSC certified.

EOLIS is offered as a flexible package that can be adapted to suit budget and application, with many possibilities for customisation.

Each building comprises of numbers of pairs of ‘bow form’ panels or ‘shells’ that are affixed to matching floor joist sections or ‘sub floors’ and to each other. A front and rear ‘elevation’, pre assembled from three sections each, are then added and an outer ‘deck’ makes up the basic structure.

After assembly of shells and sub floors, flooring and outer cladding is added to complete the building.

Price £3000.00 each
(Extras include two additional full-length double glazed panels either side of doors.)

• Rear Elevation complete with single full-length double glazed window panel, vent grill, lined and insulated. Membrane and clad with WRC ready to bolt to shells.

Price £2000.00 each
(Extras include two additional full-length double glazed panels.)


Foundations and ground works
Foundations are simple and cost effective. Depending on the site we use one of three systems to support the sub floors. On level sheltered sites, precast concrete blocks on impacted ground. On sloping, uneven and unsheltered sites, a series of sub concrete ‘pad and pier’, cast to level, or recycled plastic posts embedded in the sub concrete pad, on which to bolt and support two timber bearers. The affixed and level bearers provide a solid base on which to lay the sub floor sections and provide plenty of air space under the building for ventilation. Wooden structures using timbers with very good natural durability need to be well clear of the ground and prolonged wet , they will remain sound for many years without the need for treatment.

Costs of any of the above methods are included within the those of the basic structure. Excessive slopes or particularly wet sites will have an extra cost. Implications can only be assessed after a site inspection.

Materials
Our aim is to provide an ecologically  sensitive and sustainable approach to the building design. With the exception ot the inner ply lining (which is FSC certified Northern European Birch ply) all timber used in EOLIS is home grown and from sustainably managed plantation in the SW of Britain and is fully FSC certified.

WRC - Western Red Cedar, is used for the outer cladding, is a lightweight yet durable wood, the exposed surface of which, will mellow within a year to an attractive silver grey. Because of its innate durability there is no need to pressure treat with poisons.

Larch - Used for the bow forms of the shells, is tough and durable. Suitable for structural members, it is often used for the hulls of traditional boats.

Douglas Fir - is used for load bearing and structural components. It is also suitable for decking and floors.

“We like to think of buildings in terms of clothing. With the right clothing you can be dry and comfortable, whatever the weather. Warm and snug in the winter and cool and airy in the summer.”

The ‘breathing’ wall
Timber buildings, like clothing, need to be  ‘breathable’. Although all the timbers we use are naturally durable the curved wall system encourages good air circulation internally, avoiding unhealthy condensation (unlike the more conventional ‘box’ shape) and after a heavy downpour the exposed timber dries off leaving no wet ‘pockets’.

Insulation
WithIn all walls and under floor  -  100 mm Thermafleece is used. This is a product made from sheep's wool. For thousands of years wool has been used by humans for warm clothing, and using it for insulating houses is not a new idea. Wool has lots of outstanding physical properties and environmental benefits. When used in timber frame construction, like Eolis, it becomes part of the ‘breathing’ wall system necessary in helping to regulate moisture levels and preserves the longevity of the building. It is also safe, has good thermal performance, is local and renewable, has low embodied energy  -  very little energy used in the manufacturing process. It is reusable and recyclable, is naturally resistant to fire and can be made resistant to fungal/insect attack.

Membrane
An outer breathable membrane is installed, making the ‘shells’ effectively impervious to water entering from outside whilst controlling the escape of water vapour from within.

Planning
Some planning constraints may apply. Below is copy taken from the current National Guidelines booklet, published by the Office of the Deputy Prime Minister, in relation to buildings and other structures on the land around your house.

As follows: “Many kinds of buildings and structures can be built in your garden or on the land around your house without the need to apply for planning permission. These can include sheds, garages, greenhouses, accommodation for pets and domestic animals, summer houses, swimming pools, ponds, sauna cabins, enclosures and many other kinds of structure.

But you will need to apply for planning permission if any of the following cases apply.

 - You want to put up a building or structure which would be nearer to any highway than the nearest part of the “original house”, unless there would be at least 20 metres between the new building and any highway.

- More than half the area of land around the “original house” would be covered by additions or other buildings.

- Your house is a listed building, and you want to put up a building or structure with a volume of more than 10 cubic metres.

- The building or structure is not to be used for purposes ancillary to domestic use and is to be used instead, for example, for parking a commercial vehicle, running a business or for storing goods in connection with a business.

- You want to put up a building or structure which is more than 3 metres high, or more than 4 metres high if it has a ridged roof *. (Measure from the highest ground next to it.)
*EOLIS is NOT affected by this constraint

- You live in a Conservation Area, a National Park, an Area of Outstanding Natural Beauty, or the Broads, and you want to put up a building or structure with a volume of more than 10 cubic metres** (though it might be allowable as an extension). "
**Please note: You need to be aware that EOLIS is larger then 10 cubic metres

If in doubt, please consult your local planning authority and show them this package.

Our Service
We aim to offer a complete service, from visiting and inspecting the site, discussing individual requirements, helping to select all the necessary sections to suit needs and budget. Finally to deliver and install the building as quickly and efficiently as possible.

Services
Whilst we provide a complete building, we do not undertake to install electrics, water, gas or soil pipes. Please note: we can install hidden ducting within the walls to carry some service pipes and cables, but any electrical work must  be carried out by a certified electrical contractor to meet with current safety laws.

Contract: terms and conditions
- We will provide an initial consultation, site inspection and survey and any recommendations free, unless your site is more than 100 miles from our base,  therefore if so, additional milage will be charged at 35p per mile.

- We will provide a groundworks plan for site clearance of any trees, shrubs and invasive vegetation. Please note: we can undertake this work at extra cost, charged at an hourly rate of £25 (two people). We will install an approved site membrane to inhibit further growth of vegetation, however if you wish to cover this with gravel or any other material it will be extra and need to be laid before the sub floors are installed.

- We will provide a written copy of individual specification, including any extras.

- Please confirm your acceptance of our quote in writing with a deposit, as quoted (usually approx. one third of the total unless an alternative arrangement has been agreed).

- Our final invoice is due upon completion of the agreed installation work, payable in full.

Thank you for your interest in EOLIS.
