On Site with our next FmK ECOHome
On this ECOHome we have added further details in relation to air-tightness and cold-bridging. As a result we will have a super preforming low-energy, low-cost home.Here is a 3D Concept Image of what our next FmK ECOHome will look like
Like all our FmK ECOHomes, this one is enjoys a FULL-MASONRY build; taking all the benifits of the tried and tested cavity wall construction method; but with our innovative detailing and build spec, meaning an excellent low energy home!
Works started on site on 02nd September 2013.
Founds have been poured and footings built and subfloor is in!!
Client & FmK ECOHomes Contractor at foundation stage
Super structure due to commence 30th September...
September - From the Ground Up
Week 1 - Was the installation of the foundations and poring of the concrete subfloor.
Week 2 - Its now towards then end of September, the good weather is starting to give way and we are now back on site to start the super structure.
Walls formed on Ground Floor
The first of our specialist details are installed where we use lightweight thermal blocks at foundation level to reduce cold bridging
Lightweights blocks used to reduce cold bridging
October – Up to First Floor
Week 3 - Towards the end of week 3 the walls are now fully built to first floor level with all openings formed.
Front Elevation – End of week 3
Walls Plastered behind the Floor Joists prior to installation – this is to provide air tight construction, as concrete blocks are not air-tight, however sand/cement plaster is.
Floor Joists are installed on masonry hangers
Floor Joists are installed on masonry hangers and not built into walls – this is to provide air tight construction. when joists are built into walls, there can be small holes or shrinkage crack left after construction - these all add to the air leakage of the building.
Our FmK ECOHomes Specialist Detail for Thermal Reveals
Another potential weaknes point on standard builds is the window and door reveals - here we use our special FmK Thermal reval which helps reduce the cold-bridging effect at this point and again help the overall performance of the building.
November – First Floor Construction
Week 7 – All of first floor construction completed, wallplate installed and ready for roof trusses to be spread.
Front Elevation - First Floor Complete
FmK - Thermal Wallplate Detail
Another area which can be a weakness point on standard builds is just below the wall-plate, as there can be a reduction on the amount of insulation installed here - here we use our special FmK Thermal wall-plate detail which helps reduce this problem and create a better, warmer detail.
Stepped Chimney Detail
Ready for Roof
Early November - Week 8 and wall plates fully installed, gables and chimney built and ready for roof trusses to be installed then felt, lathed and tiled.
Week 10 - Roof completedand fully tiled, ready for the internal works to begin
Parapet Porch Roof
First Fix - Electrics marked out
December - Air Tightness Installation
Week 12 - Now that the roof is on we can start to install our full Air Tightness System as standard with all our homes.
Heat loss is a major contributor in dwellings and increases running costs and fuel costs as well as levels of discomfort through draughts and damp conditions. Installing an Air Tightness System reduces all these issues allowing for a warm, comfortable home environment.
Air Tightness Installed - 1
Air Tightness Installed - 2

Stone to Porch
Natural stone to feature front porch with feature stone heads and sills.
February - Week 14 After a very wet Christmas work started back on site with windows installed. We can now install Air Tightness tape to all windows and doors; minimising any draughts or heat loss.
Air Tight Windows
End of February - Week 17 All internal stud walls constructed and plastered.

Hot Press - Back Boiler System
Wood Burning Stove
All EcoHomes come with a Wood Burning Stove as standard. In this case the client upgraded to a back boiler stove feeding into the radiators.
Heat Recovery Ventilation System Installed
All EcoHomes have full heat recovery ventilation system as standard; this provides clean, fresh, warm air and works best in air tight dwellings.
Air Test being carried out
June 2014 - We carried out an air test for Building Control on our completed EcoHome with a result of 1.6 ACH. This is a massive improvement in standard construction which is normally around 5 ACH. At EcoHomes we are always striving to improve so we are aiming to get below 1 ACH heading towards passive level.
