You need to add something dark, for contrast and "punctuation".. I agree with the others about painting the front door black (not gray) and would also paint the planter boxes, step, and sides of the porch black. Perhaps as well the window trim and even the eaves trough although I would want to see the roof color better to decide on that. Then some brightly coloured plants in the planters and maybe a small brightly painted stool or chair or small table to the side of the door on the porch area. These things would make the font of the house "sing" and add personality so the home stands out from others around it.

I would definitely try to move the handrail to the outside of the stairs, the wider the stairs appear, the more welcoming and functional they will be. I don't think I'd go with steel though, I would keep to the era which was timber, it could be painted or stained. I also like most of the ideas and in addition think that painting the rafters a light colour toning with your overall theme will make the whole area feel more expansive. Add a feature to the entrance by way of colour on the door, as suggested or some very sleek ornament on the wall as suggested or my preference would be to feature the risers as mentioned.

Are you sure the roof is stainless steel?? That is VERY expensive and only used in very exposed corrosive coastal locations since it lasts forever. I think it might be Zincalume, a low cost but very durable and very common roofing material that has a light silvery surface and should last for 50 years. Definitely do NOT paint the roof black (or any dark colour), it would add more than 10° to the internal heat load, and you would have to spend so much more on insulation and on-going AC costs just to get back to where you are now. Have the roof checked and repaired by a roof plumber instead. If it's an old leaky galvanised iron roof at the end of it's days, replace it with zincalume. The porch roof looks like it needs replacing, but I would replace it with new roofing, possibly the insulated sandwich panel kind, that has a smooth white underside, then add a gutter to the front edge so you don't make your visitors walk under a waterfall in the rain. The canvas awning suggested earlier would not last as long without looking tired and would require the removal of existing roof structure, so I think it would be the more costly option (and you would still have the waterfall problem). I would leave the front fence as is, it ties in nicely with the house, but trim the tree. The back deck could easily be roofed to match the front, and be more useful to tenants with weather protection. It would be good to make all trim colours the same, and against the cream brick I think the dark grey you have on the front door and columns works quite well. I would make the other windows and trim, as well as the weatherboards over the back door match that if it just involves painting. However, it's not essential and if it means changing powdercoat finishes it would be too costly to be worthwhile in a rental.

Thanks a lot for your reply, much appreciate it. The guy has been doing some work for me and he charges always reasonably so I don't ask for a quote from him. But for this work he said he will need a day and a half with his worker to finish the work and he said that the light frame I have for an internal fence would be good for the gate. Anyhow I was surprised when he constructed the current frame somewhere and brought it home and attached the wood to it. He didn't consult me regarding the new frame. I realized earlier that he is facing difficulties with the work but he dismissed my thoughts and assured me he will manage the work. I didn't discuss the width with him as the case with few jobs where I relied on his experience. Anyhow he got recently a contract for a big project and started delaying my work and I noticed some issues with another job I assigned him to do it because of lack of time. I had to return the motor I bought back to Bunnings after he said to me that he will google how to install it and when I saw that he is having trouble installing the rollers and the one he bought were not long enough. See attached image, he bought the one to the left when he should buy the one to the right. A friend of mine who is a builder examined the work and said there was no need to dig for a channel and it cold have been done without the channel by lifting the gate-guide and extending the length of the rollers or using larger rollers like the black one and he also said that the gate doesn't require such heavy frame.
