  • Hi Geoff,

    My husband Jeff and I are looking at buying a small mudbrick house in Aireys Inlet and in searching for more information about mudbrick buildings and how easy or difficult they are to renovate I came across this posting of yours. It seems like you have done exactly what we were thinking of doing (if we buy the place) as the current house is very small and quite dark.

    I was wondering if you would be willing to discuss your renovation with us and maybe answer a few questions we have about such a project. I am curious as to how you found the process of addng on to a mudbrick house? Was it easy to make additions that joined well with the existing structure? How have you found your extension has performed now that you have been in it a while?

    Sorry to be so intrusive it just would be great to gain some of your insight before we jump into buying a similar house.

    Thank you for the great post and photos!

    Best regards,

Slide Show For Hopkins Street Solar House Day

  1. 1. Once upon a time………
  2. 2. There was a cold, dark, mud brick house Nth verandah too wide & blocked winter sun Mudbricks are a poor insulator
  3. 3. Then we started…with a slab! the slab is a great thermal mass
  4. 4. Then the framing started…… window spaces to allow more light and solar gain into living areas
  5. 5. And went up real fast! Skillion Roof Line was a part of the design brief...we like the look!
  6. 6. … taking shape!!
  7. 7. We tore down the front of the house…walls & windows & verandah let there be light All windows & mud brick walls removed
  8. 8. & removed walls of mud brick
  9. 9. East Elevation taking shape
  10. 10. Then the deck started……
  11. 11. … .and continued for a while Cyprus Pine decking (macrocarpa) milled from trees in Aireys Inlet
  12. 12. And then took shape!!
  13. 13. Meet our builder…..Gary Setchell
  14. 14. And his assistant…Michael Bradshaw
  15. 15. The cladding…..color-bond Color Bond steel - lightweight and the color is "Jasper"
  16. 16. & rough-sawn plywood Ply cladding is light & has low embodied energy
  17. 17. Then the window & door frames slotted into place Mouldright Joinery made our windows All new windows double glazed, argon filled with low e coating = comfortable living
  18. 18. Window timbers Mouldright Joinery made it easy All window/door frames made from Plantation Hoop Pine
  19. 19. And then we were at lock up! Mouldright re glazed and fitted new casements to some existing windows
  20. 20. Time to insulate the walls and roof space No insulation yet
  21. 21. Then we filled every gap we could find!! R3.5 Bulk insulation - roof
  22. 22. The walls need it too! R2.5 in the walls
  23. 23. Passive Solar Gain…..comfort ++ Sunlight entering from the north this heats up the room during the day Insulation in roof & walls slows the loss of heat at night Double Glazing also slows down heat loss in winter
  24. 24. Plastering sucks!!
  25. 25. The boys needed a break
  26. 26. Feature Posts existing cyprus pine post new cyprus pine post also milled from an Aireys tree!
  27. 27. Plastering and painting done!! sashless double-hung windows great for ventilation Upper casement windows for extra ventilation
  28. 28. The Pergola goes up! North Eave wide enough to keep mid summer sun out Deciduous vines will act as additional summer shading
  29. 29. The North orientation! Winter Sun gets in Summer sun blocked shade line at noon in late Sept shade line at noon in mid June shade line at noon in mid summer
  30. 30. Feature Timber Benches!! Cyprus Pine benches...sustainably minded! Re used timber from old verandah
  31. 31. And for the Floors!! Reclaimed Messmate flooring looks superb...milled from old structural beams
  32. 32. And for the Floors!! The Floor Polish product is called Bona Mega A water based product from Sweden Product Source = Ezi Floors in Melbourne * water based * no discoloring in sun * non toxic
  33. 33. Hot Water from a Heat Pump
  34. 34. Ecological Sustainable Design Principles <ul><li>Passive solar design </li></ul><ul><li>Maximise insulation in roof, floor and walls </li></ul><ul><li>Low embodied energy cladding </li></ul><ul><li>No use of any “un-sustainably” harvested timbers…..compromised with arcs/skirts </li></ul><ul><li>Re used as much of the old building as possible…timbers, windows, doors etc… </li></ul><ul><li>Disposed of all chemicals and waste sustainably </li></ul><ul><li>Use of water based-low toxic paints & wood seals throughout </li></ul>
  35. 35. Compromises along the way <ul><li>Used “Eco-select” hardwood for Arcs and Skirts… </li></ul><ul><li>KD Hardwood used for the heavy double-glazed French-doors…. </li></ul><ul><li>Paints were water-based but did not have natural pigments </li></ul><ul><li>Opted for down lights in some areas instead of pendant fittings with compact fluros </li></ul>
  36. 36. Things most proud of <ul><li>House started with a ZERO energy rating and has ended up better than 5 </li></ul><ul><li>Locally source timbers for posts and deck….reclaimed messmate flooring </li></ul><ul><li>The Floor Seal – Bona Mega from Ezi Floors </li></ul><ul><li>The design and level of comfort – Third Ecology </li></ul><ul><li>Quantum Heat Pump – Sun Works Eco Plumbing </li></ul><ul><li>Managed to keep within budget $$ !! </li></ul><ul><li>We made every attempt to source “greener” products where available </li></ul>
