That's what I call a garden. I'm tired of looking at landscaping plans that don't seem to include any plants! Just paving, pools, decks and outdoor furniture. We used to have a jacaranda when we lived in Perth and the beautiful carpet of flowers in spring and summer was amazing. Just saw SaveH20's response. I was so busy looking at the tree I didn't notice the ladder! Do the kids pull the ladder up into the cubbyhouse when they don't want to be disturbed? Re: Restrictions on black roofs and roads? 23Dec 05, 2014 10:42 am I believe even some Councils have restrictions on how light a roof a dwelling may have - as a measure to protect nearby residents from intense glare from the roof, but moreso to maintain visual amenity by not having a roof that sticks out above all others. Certainly many body corporate subdivisions with covenants will have roof colour restrictions - agree with Lilliana, those restrictions are just plain ridiculous sometimes! On the flip side, I see many new houses up here in the tropics putting very dark roof colours on their house. Many obviously just choose the colour they like without thinking about solar absorptance, they simply dont know that dark roof = more heat absorptance from the sun = hotter ceiling space = hotter house Sarking such as aircell reflective foil over the trusses no doubt helps a bit, but many builders up here still dont offer this as standard and stick with batts instead - which is great for the 2-3 weeks of winter I had to go a medium coloured colorbond roof - Windspray. Not just because lighter colours are frowned upon, but because the lighter colours looked quite ugly. The house still has to look half attractive Dale - Building Newbie Proserpine, QLD Re: Restrictions on black roofs and roads? 24Dec 05, 2014 11:45 am Our council in rural WA does not allow shiny rooves such as zincalume, they claim it is because of the blinding effects on pilots. Our latest roof is surfmist colourbond which I note performs better thermally than plain zincalume.

Sometimes, but I've usually got to tell our daughter and her friends to tone it down so they don't disturb us ! I ran power to it with an RCD safety box that they could plug in a light, a stereo and a little toaster oven so they can cook toasted sandwiches out there. They have had a lot of sleepovers in it. Our local councils also restrict a few light colours in the Colorbond range and raw zincalume because of reflectance. SaveH2O is that a dogleg stair ?

I actually wanted Surfmist for my roof, but the interior designer consultant said she wouldnt give it to me as it is ugly and I will regret it. Should have dug my heals in!

WHo pays your winter bills I dont think dark colorbond roof is as bad as a dark tiles roof. It looses its energy very quick when the sun disappears. Re: Restrictions on black roofs and roads? 31Dec 05, 2014 7:47 pm B STAR WHo pays your winter bills I dont think dark colorbond roof is as bad as a dark tiles roof. It looses its energy very quick when the sun disappears. I'd have to pay my winter bills, but 6kw of panels to go on the roof of the new house will make that bearable. Not forgetting that I'll effectively have R5.3 of insulation in the roof to keep the warmth inside the house. Agreed, colourbond will always lose the energy far quicker than a tiled roof will ever do.... surfmist tiles will still heat up and keep the heat there, where colourbond won't.

Just realised your in sunny qld!!!!! Do u even need a heater in winter? Re: Restrictions on black roofs and roads? 33Dec 05, 2014 8:13 pm I have colourbond Surfmist metal roof on my build and white gravel outside around my build. I designed my house as passive-solar with light weight (weatherboard) external cladding and internal double brick walls. Last weekend (my house is now at lock-up stage) it was 28 deg max inside whilst it was 37 deg outside for most of the day. This means my air-conditioning bills will be almost negligible once the house completed. A light coloured roof plus careful shading of external windows really does work and my house is not even finished yet. I only wish the local snake population were not so aware of the benefits of solar passive design.

The panels also keep the roof cooler. Particulary when you add more and more as we intend to do as we progress towards hybrid then off-grid at a later date. The roof itself will get plenty of shade with the panels, and what doesn't get shade I'll have plenty of hot air flow out of the roof with my solar powered fan I have on it. Minimise the amount of heat getting in during summer, and insulate well for winter so heat loss will be reduced. Owner Building at Jimboomba Woods in Logan City Qld.

We have incorporated some passive solar features, verandah and north living areas, tiles for solar gain and part weatherboard frontage as well. Snakes???? I thought snakes preferred sunny spots for the heat. Or do you mean your house was warmer in winter so they sought it out? Re: Restrictions on black roofs and roads? 37Dec 06, 2014 12:35 pm Snakes don't like it cold or very hot. They like it in between. I see most reptiles on warm winter days, mid season or cool summer days. I have a lizard that spent the entire winter hibernating in my toilet. This lizard left of its own accord when the first warm days of spring arrived. Kangaroos spent the winter living in my house (it was not lock-up then). They recognised my car and would move outside as I arrived and would start to move back when they saw me packing the car. They did not even wait till I was out of sight, I could see them in the rear view mirror moving back in as I drove off.
