Abbé Warré's book
The Ecological Hive (La Ruche Écologique) of J-M Frèrès and J-C Guillaume
(sometimes referred to as 'Warré-FG')

Possibly the most popular variant of the Warré hive is that developed by Jean-Marie Frèrès and Jean-Claude Guillaume as presented originally in their 430-page manual L' apiculture écologique de A à Z (Villelongue-Dels-Monts, 1997). This book has so far been available as a bound printout from a computer in A4 format. However, Jean-Claude Guillaume has produced a second edition, dated 2011, which now comprises two A4 volumes in the same style and format, totalling 804 pages. This was published in Belgium in early 2012 (Editions Marco Pietteur). A publisher is sought who is willing to invest in the translation for an English edition.
It is a book for intended beginners and contains dozens of meticulously drawn diagrams which detail, step by step, various beekeeping operations. The approach is informed by many ecological or organic principles. The most important modification to Warré's original design is the introduction of shuttered windows in each hive-body box. The other two notable modifications are the insulated, ventilated roof with an integral quilt that moves up to accommodate a feeder, and the use of mosquito net instead of coarse cloth (hessian/burlap) under the quilt, i.e. the top-bar cloth. A more recent version has a modular roof which has the feeder unit, quilt and roof per se as three modules (see below).

As indicated above, the book contains a cost-benefit analysis of honey production in 'modern' frame hives versus Warré-ecological hives. The two costings (including the annual time taken per hive for each) have been translated and presented side-by-side in tabular format: guillaume_cost_benefit_analysis_2012.pdf .
Roof (original version, 1997 edition of book)
As the roof is possibly of particular interest for dealing with condensation in cold climates we describe it here in some detail. Its main body is the same outside size as a hive-body box. To create a weather-proof seal with the box on which it rests, 50 mm wide battens are nailed round the lower rim on a 5 mm thick spacer so as to project over the hive body box below and yet give clearance to aid removal. A weather-tight seal is made with silicone along the top rim of the batten. The body of the roof box slopes from 180 mm to 150 mm forming a single-pitch roof and a large cavity big enough to fit a feeder. The roof box is closed at the top with a sheet of thin plywood. On top of that is fixed a 30 mm thick sheet of polystyrene/styrofoam insulation (protection from solar radiation). On top of that is the sloping roof board of plywood of an adequate thickness covered with roofing felt. A 60 mm diameter ventilation hole is bored in each side of the box and covered on the inside with insect/mouse-proof mesh.
A significant further innovation with the roof is that a piece of cloth (wool) is pinned to the inside of the roof near its base to form a seal all round. This cloth normally rests on the mosquito net. On top of the cloth is glued a sheet of 50 mm polystyrene/styrofoam. This assembly is the quilt. There is sufficient slack in the perimeter of the cloth that when a feeder is placed on the top-bars and the roof replaced, the cloth, with the sheet of polystyrene glued to it, is automatically pushed up to accommodate the feeder.
The roof differs from Warré's in a number of significant ways:
Roof (modular version, 2011 edition of book)
The integral roof with inbuilt 'floating' polystyrene quilt and space for feeder develops to a 3-module system comprising feeder module, quilt module and roof containing the ventilation chamber.

The modular roof is described on pages 74-77 of the 2011 edition of the book. An illustrated translation of those pages is downloadable here.
A window of 4 mm glass is fitted to each box on one of the sides not having a handle. Its aperture is 100 x 300 mm and it is set in 7 mm x 4 mm rebates above and below. It is closed on the outside by means of a shutter insulated with polystyrene/styrofoam. A detail of the window construction is shown below.
Having windows in a Warré hive is likely to appeal especially to the beginner. You can see to a certain extent what is going on inside, especially how far the comb has developed downwards. However, it is surprising how little of the life inside the hive is visible compared with removing and examining frames. Experienced beekeepers therefore may prefer to rely on information obtained from observing the hive entrance or, if necessary, by tilting one or more hive boxes to look underneath. It is doubtful if the windows justify the extra complexity and cost of construction involved. Furthermore, the use of polystyrene and glass increases the embodied energy and use of petrochemicals, both of which detract a little from the sustainability of this variant. Warré managed without windows and so do a number of contemporary Warré beekeepers.

First UK 'ruche écologique' (Warré-FG)?
The following is a description of Trevor Ray's experiment with the Warré-FG. The western red cedar Warré hive (before modification) was supplied by Matthew Mercy ( http://www.zorbanet.com/warre/ ).

The mesh for the top-bar 'cloth' and for the quilt contents retention 'cloth' is fibreglass fly screen coated with PVC.
After fitting the mesh and battens illustrated above, a 40 or 50 mm batten skirt (white in photo) is fitted around the bottom of the quilt, overhanging 20mm of the top box in order to cover what would otherwise be an exposed quilt top box joint. The batten is made weather tight by sealing with a bead of silicone. The quilt contents are contained in a mesh laundry bag.
A further modification being considered is a layer of insulation below the mouse board. There is space for it above the roof vent holes. Note that the roof is also vented above the mouse board, as per Warré's pitched roof design.
