@barskits Err, I know 🙄 We've owned loads of period houses - everything from Tudor through thatched Georgian to 1850s-with-Arts-&-Crafts makeover.
I wouldn't suggest a sledgehammer in any case, as someone would probably love it...you perhaps 😁
We always sensitively renovate (as we've never bought somewhere that wasn't a project), and are currently restoring a Georgian cottage with absolutely zero original features as they were ripped out last time it was renovated in the mid 1960s. Everything including the skirting has gone, so we're putting it all back as it should look.
However, despite @missrachael having what appear to be some lovely original windows in her new - Edwardian meets Art Deco? - home, and although the fireplace shows an Arts & Crafts period influence, imo the 1920s/30s is just not the most attractive period and - I think - not the loveliest fireplace. I accept I'm probably in the minority thinking this!
I'm probably biased as I grew up with those kind of fugly fireplaces in my parents' (1925) and my grandparents' (late victorian, where the fireplace was obviously a later addition) houses.
We also collect Arts & Crafts and Art Nouveau furniture/decorative items (and books on the subject of which I have hundreds), so know a bit about the period.
Of course, @missrachael might decide to keep the fireplace, but personally I would replace it with something more typically Arts & Crafts or Edwardian sourced from a reclamation yard or similar. If the fireplace comes out OK they might be interested in purchasing it. I know we once sold a very similar example (from a Victorian detached villa that had been 'upgraded' in the 1920s or 30s) to someone restoring a 1930s house.
