adding features from older houses can only improve the house if done tastfuly of course
Hmmmm, not necessarily, I live in a 70's built house, all the bathrooms / kitchen / doors / windows, flooring, staircase heating system plus god knows else have been replaced, however putting period features in this kind of house would look absurd. Some examples :-
Parquet floor looks nice IMHO in some houses, in ours it dates it to the 70's. Now has maple wood engineered floors, which no double will go out of fashion if they haven't alerady.
Coloured bathroom suites do not look good anywhere. Nor do mock victorian suites in modern houses.
The staircase, was one of those ones with planks running parallel to the rise of the treads (looks awful, spindles look much better) but anything overly ornate would look out of place.
The doors were those horrible office like dark brown with prominent grain running through them, complete with aluminium door furniture absolutely hideous, but apparently the height of fashion in kitchens at the moment (Grand designs this week - Yuk!!!) Now has simple wooden ones
Windows, PVCu windows looks terrible in period houses, some will argue that they don't look any better on modern houses, however, the fact that our house has plastic everything outside, doesn't detract one iota from it's looks (it was ugly then, it's ugly now)
Kitchens, OMG what is going on with kitchens at the moment, design guys listen up, they look awful! Why on earth would I want an extractor that looks like a chandalier, it doesn't add a touch of class, it's chavy, bling, and tasteless.
Fireplaces, victorian fireplaces look great in period houses, they look sh**te in modern houses, clean and simple is the key.
Anyhow, that's my advice, taste though as they say is totally subjective.
