Passive Budget Build

The Passive Budget Build package is designed to suit self-builders who want to build a Passive House. We supply the airtight insulated shell and the self-builder uses local trades to do the electrics, plumbing, 2nd fix carpentry, plastering etc,. We can supply the insulated, airtight shell for as little as £32/ft2 and can be gone from the site in 2 months, if the windows arrive before we leave the site these can be fitted, otherwise we seal up the window opes and air-tighten the shell.

I sent this quote to a Selfbuilder in Sept 2011, it gives an idea what is included in the “Passive Budget Build” package;

Hi A***

Please find my revised quote of £89,500 for the Viking "Passive Budget Build" option for your 2500ft2 house in Wicklow.

The following items are included:
Passive Slab foundation system, supply and fit with a 0.10W/m.K U-value and zero Cold Bridges.
Warm Stud timber frame with a 0.10W/m.K U-value for the walls and roof.
Supply of Isover 34 insulation for External walls and roof.
Air tightness levels of 0.6ac@50kPa.
2 FiWi Heat Recovery Ventilation units.

The following items are excluded;
External Windows/Doors.
Plastering/Plasterboard.
Electrics.
Plumbing.
Internal doors, Stairs, Architraves, Skirting.
Slates/Fascia

The following are also excluded but may be considered as an option to heat the house;
Solar Roof @£120-£130/m2 roof area.
Solar Slab @£25/m2 floor area.

The larger the Solar Roof area the smaller the Solar Slab you need and the more responsive the system becomes.

You can render directly onto the EPS, put on a Cement Board or build an external block, the cement board option would be the most expensive the other 2 are about equal in cost.
