I see Dawn as being rather polished. And inclined to show-off.
Walls of stone or brick, and likely plastered. Roofs of bright tiles or thatching with fancy show-pieces on top. Internally wooden joists and beams, likely with a little carving decoration.
Wooden sheds and outbuildings, but anywhere where people live is going to be pretty sturdy.
The larger houses are likely to display trophies in the form of military souvenirs, mementos from competitions, or even a House sigil that they serve/served atop the door. Tradesmen and skillled artisans may well have a series of small shields, each painted with a House symbol, on their door, signifying their noble customers.
And then you come to the Houses, which are highly varied. Ranging from fortified manor houses (with crenellations and watch-towers), to slightly over-ambitious castles in the late medieval French/English styles. Often white-washed or in pale stone, with any ivy or similar pruned to ornamental levels. Roofs of slate or tiles, and many flags of the House and Nobles in residence.
If it can be built in a shiny and impressive manner, it probably has been. If it can be ornamented, it likely has been. Carvings, paintings, mosaics, flags, statues and inlay abound. Often with a subtle (okay, not that subtle) note saying who’s responsible for this glorious work of art.
