You can buy the arch and corbels from a plaster supplier. You then need a builder to frame out the arch. They’ll rip off some of the existing plaster and frame out the arch in wood. You’ll then need a plasterer to cut and apply new plaster and join with old. They then add the arch and corbels. You’ll need to paint too. Working with curves can be tricky so it may be hard to find a tradesman. Good luck.

Unsure how to cover this utility hall floor. previously carpeted, and ripped up due to washing machine leaks, heavy wear and tear, i did put new grey carpet in bedrooms 1 and 3 and formal lounge. the door shown is bedroom 2, needing to replace its carpet hoping for some sort of flow, but if its different oh well its guest room anyway. i cannot match the existing grey tiles. what can i do, it needs to not look odd with the flooring in family room kitchen and hall leading to portico front entry. I do not like the reddish laminate and its worn in some areas. do i replace all or some or is there another idea? walls will be painted grey with white trim. not a fan of existing beige . original thought was chocolate brown main hall, was told my house too dark. and doesnt solve problem of not wanting laminate near laundry, other thoughts - some sort of large white tlle? too clinical? terrazo with a greyish fleck to match wet area grey tiles- too modern industral? my style is perhaps Hampton without the beach (lol) family, pet, guest, grandchildren friendly, overstuffed sofa, lots of photos and fresh flowers. perhaps will replace wooden blinds with long flowy airy white. other pics show the new carpet -i love its texture, and the nasty reddish laminate. maybe i can leaver some and cover with rug? any ideas gratefully accepted.

Thanks Lockmac, looks like you have master and en-suite before living room so prob a good 5 metres of hall or more at 1.8 wide before you meet living room. That is a great greeting space. You can then narrow to 1.5 outside living room. The 300 mm would be better used in that room than hall, the walls u circled for me. You should also add doors, perhaps large glass sliding door, to the living room as I note it has a tv and sound travels. My biggest regret is not having a door on my living room of the family/kitchen due to noise issue and sadly can’t add one due to several constraints. Thankfully I did add doors to hallway leading to bedrooms both for privacy and noise control.

Are you on a slab? You may be better trying to add a toilet to the laundry. How wide is the hallway you’re proposing to use? Having it open off a living area is a terrible idea, especially with a sliding door. You may be better, depending on width, entering where you have the cupboard drawn.
