Your house was built before 1870, but after 1820. It could be called 'Italianate' from its paired windows on the second floor. It could also be called "Folk Victorian" . The length of the windows, the window casings with their small hoods are all early Victorian. The window panes (2/2) are probably renovations from the early 1900's. Its eaves, which extend straight out with no returns back to the main house, are Italianate, or 'Romantic' - a reaction to so many years of 'Colonial' architecture in the beginning of the Industrial Revolution. You can see that the builder is still thinking in terms of 'Colonial' symmetry but beginning to use the frills ( bay windows, paired windows, fancier door and window casings) that became so popular in the later Victorian years. The bay windows and the porch make it more likely to have been built closer to the 1850's. Also the newel post in the second slide is made from one log, turned on a lathe - very popular from the late 1830's to the 1860's. However your other stair railing, balusters and the fireplace mantles are the style of the 1830's. I know a similar hand rail (how lovely it is to look at and to feel in the hand!) built by a factory owner in 1838. The iron fence is probably later, early 1870's, as are the spindles (the little turned pieces up next to the roof) on the back porch. See if you can find a copy of Asher Benjamin's pattern book published in 1830 or 1827. He was a very popular architect whose books were copied by local carpenters all over the US. The 1827 and 1830 editions have illustrations very similar to your pictures. Also you might enjoy 'A Field Guide to American Houses' by the McAlesters.

Ahhh...so you've used Baquacil for the last 6 years until now? Yes? You didnt' say that in your first post. And right now you're using chlorine tabs in your skimmer and shocking the pool with a chlorine or non-chlorine based product for sanitizer instead of the Baquacil peroxide "shock"? Just trying to get this all straight. Are you in the middle of a Baquacil to chlorine conversion? That is a specific process, and it takes some patience to do, during which you'll see different water colors and clarity as you convert. Of course, as you already probably know using an OTO test (which shows yellow in the presence of chlorine and tests up to 5 ppm of Total Chlorine only)...a brownish red color means that you have a much higher level of Total Chlorine (Free Chlorine plus Combined Chloramines)in the water. You'd need to use an FAS/DPD drop test to very accurately determine up to 50 ppm how much Free Chlorine, Combined Chlorine and Total Chlorine you have. I use this test on my own pool frequently and it's very easy to use. I still stand by my advice. There are detailed instructions and help on TFP for Baquacil users who need/want to convert to a less expensive product, as well as immediate help with your specific issues. Cheers and I hope you get your problem solved and get back to enjoying your pool!

I say buy the set. Paint the chairs light or better yet, get an antiquing kit so you have some gold paint in the faux worn areas. Then lightly sand the table top to paint glossy or just use a tablecloth. Your kitchen looks like it's going transitional bordering on contemporary. I don't know about the rest of the house. If you wanted, you could go more eclectic in the dining room; depends on your layout & how the house flows. Better if you love it but I understand budgets. The 8 chairs alone might be worth the money given what basic chairs would be even at Walmart or Lowe's. Do what fits your style & family.
