If you want rusty corrugated just get some mild steel rolled by your corrugated supplier. galvanising is way too hard to remove and will actually cost more than rolling new mild steel sheet. If you want fast rust just give it a light grit blast to remove the mill scale. It is not really needed as it will get there after one winter anyway ( as long as it is in full weather.

You would have to ask SCA. I believe the gable roofs are for council (streets-cape). The cladding being corrugated, cost (pre-finished) and proximity to the coast (durability).

I think the other issue to consider is the iron ceiling might not be able to hold the light fitting due to weight and being thin too. I'm wondering if you can cut out square or rectangle shapes in the iron and fixing timber block painted silver where you will be able to cut out the perfect shape of the down light and the timber is fixed to the roof structure so the light fittings will be able to be installed safely??? The iron roof than is butted up to the timber blocks in the ceiling.

Hi Pottsy99, thanks so much for your thoughtful response! You are perfectly right about that infill panel and the original steps which had been removed - goodness knows what was going through people's heads to do this to an old house. I do intend to reinstate the stairs - and link to the front garden which is north-east facing so will be perfect for an informal edible garden. I'm thinking of finding some original encaustic tiles to do the porch floor. It's a good idea to reinstate the steps in concrete - I was thinking about timber on a steel frame (for costs) however concrete will give a more stable feeling . This old California Bungalow however has an perplexing design in that there appear to be two entrances - apparently this was not that unusual for California Bunglalows. The main hallway runs off the side entrance, whereas these steps which come from the front garden lead straight into the loungeroom, with no hallway. So I intend to keep the main entrance to the side, and make the front entrance relate directly to the front garden, using plants and lighting to direct people to the main entrance. anyhow, in regards to the colour pallette, I love your idea of a burgundy roof, however I'm going to tone it down a bit as there's a lean-to at the back where I can have some fun with colour. For street appeal I'm going to keep it toned down - the setting is an Australian bush garden, and I'm looking at a relaxing pallette of greys which I think will make the red bricks sing as well. I've had the red bricks and mortar colour-matched at the hardware store, and there are red/yellow/black tones in them. So the greys will be warm/ olive-greenish. The light colour will be a lighter hue of the mortar (very light beige). The front door will be bright red, with warm white/very light beige trim. thanks again for your thoughts :-)
