Roof and gutters

The installation of our first floor roof and gutters is proceeding. Jen kindly took these photos this morning, because it is difficult to see progress from ground level.

Under the tarps, the gable roofed verandah has progressed significantly, but it won't be completed until the first floor is roofed and rendered.


  1. Dave,
    Are you re-roofing the rest of the house in metal? Interested in the design side as well as the green credentials - how does it mesh?
    What are the green benefits for having a tin roof in Melbourne? I know it works in Brissie with good roof ventilation, sisulation, etc, but not sure about cold climates.

  2. Yes, the whole house will be Colorbond. I have to confess it was chosen for two factors - we wanted the look AND it is cheaper. Part of the lower cost is the cheaper structure to support it. In the existing house, the roof is sagging a little in places, so changing to Colorbond will see that fixed when it is installed, taking the load of the ageing roof, and a much lighter structure built for the extension.

    In choosing the Colorbond we went for a mid-range colour, and paid extra for a Thermatech coating. Thermatech is claimed to be a coating within the Colorbond that reflects infra-red radiation, keeping it cooler in summer. Since paying extra it has become a standard feature. It can also shift the Colorbond colours into the next energy efficiency range, ie a medium colour with Thermatech can have the heat transfer performance of a light colour (or a dark colour with Thermatech performs like a medium colour).

    The house extension is (so called) 5 star energy rated. We're paying extra for roof insulation through the whole house, and in the extension, wall, floor and roof insulation.

    As for the energy performance of Colorbond vs tiles, I've no idea.

Walk-in pantry: advice for designing yours

Now we've been in our renovated home for a week, we've picked up on some minor issues that anyone considering a walk-in pantry or butlers pantry may want to consider. I think we got ours right, and the minor issues are ones we'll correct ourselves, shortly, at low cost.

 Our pantry is exactly that on most days - a pantry. There's no sink, no oven or hot plates, and no exhaust fan. It does have a microwave and a milkshake maker, storage for irregularly used appliances, and a bench top that can be worked on. We could fit plumbing for a sink later, but can't see a need right now.

Big cost savings can be made with a walk-in pantry. By having a separate room and door, there's absolutely no need for cupboards and cabinet doors within the pantry. Think of the pantry as a cupboard!  Bench tops can be practical and not showy - you don't need Corian or Caeserstone surfaces. A walk-in pantry is a separate room, so soft-close drawers to keep noise down aren't …

How to install a new garden tap for your vegetable garden

The day before the turf for our lawn was laid, I used a trenching shovel to quickly dig a trench from our existing tap on the back wall of the house, to the edge of our raised vegetable patches.

I laid a length of 25mm blue line PE pipe ("poly-pipe") and back filled the trench. I fitted a right angle elbow fitting to either end, with a short length sticking in the air, clear of the soil, so the line wouldn't become blocked.

During summer, our gardening efforts were focused on establishing the new lawn, so we didn't plant any vegetables.  Then last weekend, about six months after we laid the lawn, I completed the garden tap after speaking to a plumber about my options for connecting the pipe to the water supply.

In the end I took the easy and cheaper DIY option. At Bunnings I bought the tap fittings for the garden end, and quickly screwed it together.  A star dropper and some cable ties provide temporary support until I put in place a more substantial post.

Monkey bars!

A few months back we picked up a discounted set of monkey bars (aka horizontal ladders) from Bunnings.  They were reduced from $299 to $80 because the packaging was damaged and the bolts for attaching the bars to wooden posts were missing. There were about four sets of bars on sale.

Last weekend I started assembling them myself, using about an extra $175 worth of materials (bolts, washers, nuts, four cypress pine posts, quick set concrete).  When it came to erecting them I needed a helping hand, which I received yesterday.

In the process of working out how and where to assemble them I found that the recommended height is 1.8 - 2.0 metres, and preferably 1.8m.  Soft fall is also important, to a depth of 250-300mm for up to 2.5m around the bars (Playground Equipment Safety Bulletin, February 2011). The Bulletin provides advice about selecting soft fall materials.

We've generally followed this advice, although without soft fall for a little while. The Bulletin identifies the following…
