Our local locksmith has lots of quality handles on display. You could visit yours if it’s open.

Levers are much easier to use than knobs particularly with you hands full so I prefer them on external doors. I thing they are better with large heavy doors that need a large latch to secure them as a knob would take more turning. Also think about the other hardware on the bifold. Are there long handles to pull those doors back and how would a knob match

i second black, one of our clients mixed black handles with silver taps and it worked, it will definitely work with brass features as well. the black wont fade if cleaned with the appropriate products, just choose a matte finish with low grains

Hi, firstly congratulations on the new purchase. If you are on a tight budget then painting is certainly an option... you can do this yourself if you are feeling particularly DIY inclined or you can also have the doors and panels painted professionally in a polyurethane finish. Dulux does a great range of renovation paints that people tend to get some good results with. If you go the poly route bare in mind there will still be a significant investment required. Green cabinetry with timber accents would look great. Either a darker shade or you could look at sage perhaps, which is very popular at the moment. You could add some open shelving on the wall where the hanging scales are currently positioned. White is also an option as its timeless but everyone has a white kitchen. If you're going to renovate and this is your home for the foreseeable future dare to be bold and add some colour in your life :) Timber benchtops would be lovely but they are very expensive, especially at the moment. You could however add a timber top on the island as a butchers block type feature and update the back bench with either an engineered stone or a laminate. You could add in some brass or black handles and depending on how far you want to go update your tapware to match to finish the look. Good luck with the renovation!
