Thanks for this suggestion. I've just had a look at a photo of a fence painted in this product and it looks great. ... It's been almost three years since we posted our original question on this site and we still haven't painted the fence! Some parts of the fence have turned grey, as they are exposed to more sun, but overall I do think a dark charcoal finish would be more attractive. :)

Look at 'Iron Ash'. Its a treated version of what you're after. Don't know anything about it but seen it recently on the web. Overall avoid Merbau as mentioned above, as well as being an imported 'sustainably' managed timber.... Use local product's when available as they're manufacturered to high standard's, supporting local job's, companies must meet tight regulation's, etc. unlike other countries....

Thank you everyone! Between you all you have summed up my concerns (changing bulbs, enough detail already in the stairwell, honouring the old house) and my desires (a nice lantern pendant or period light, LEDs need less changing, overhead lighting. I like the idea of the wall lights but we have not wired for this. There is wiring for for stair lighting (phew, glad we got that right) and one down light in the middle of the void. We have reconsidered a pendant as the one down light will be harder to change but are worried about obscuring the windows. Perhaps one of the simple fine-framed lantern pendants or white vintage light, on chains will be easier to change as we can pull it across to the stair, or a pulley pendant like this I'll post some more photos of our reno once its further on.

If you were selling , are you sure you will recoup the extra $$$$ ? Get it wrong , and a potential buyer will walk and/or offer $50k less , whereas if you leave it as it is , they will know it needs replacing , offer $10k less , but you have gotten an offer ! Just me , but what I would do is rip up the fake tile lino in the foyer ( I assume it is lino -- it doesn't look to be 'proper' tiled ? ) , and do that in a darkish timber laminate -- slightly lighter than the front door , slightly darker than the stairs . Or go really dark -- almost a dark weathered grey or a similar dark brown to the drawer unit in the lounge -- the rest of the colourings will lighten it a bit , but it will all tie in . OR actually tile it , maybe a black or charcoal gloss marble or marble effect with lighter streaks through it ? The house and colourings look an older style , this continues that theme , but I feel white or beige tiles would look too bland . $2k max instead of $10k -- marble tiles may be more than $2k , but up to you .
