    I did a quick search in here and all I could find was from 2008-2011 so I thought this worth asking..

    We have improved air-tightness of our new (to us) house. It's not anywhere near passivhaus standard but with room-sealed log-burner, other chimneys blocked up and back-draught blockers in all (four) ventilation ducts and nice new tight-fitting windows (non-opening where poss) and doors I would hope it is good enough to allow a cheap Nuaire PIV fan to raise pressure in the house slightly and help keep radon out.

    And now we have to consider the letterbox. I've pretty much accepted that if we're to have one at all (rather than a US-style mailbox outside) then it will be in the front door. I'd still like something not too leaky to help keep that small positive pressure up.

    Does anyone in here have any new recommendations?
    Approaches or products that might be suitable and decent quality and good looking etc?

    PS: Other useful old thread here:-

    Having been a paper boy and a postman (for a few weeks) I appreciate the need for a post box that is easy to open so no strong springs. It also needs to be large enough to get a folded copy of the Sunday Times through it !

    I've quite like the idea of the "through the wall boxes" down this page but I don't know how well sealed the inner door is...

    To be considered in tandem with the catflap.

    Just put it on the wall next to the front door - I find no problem with this.

    I think letter boxes as in a hole in a door are a thing of the past, external box on the wall for me.

    Indeed letters are becoming a thing of the past too.

    Agreed. Instead (unless you have a delivery point within walking distance) you probably need something like this - https://www.parcelhome.com/

    And maybe one of these to solve the cat-flap problem? http://www.purrfectforcats.co.uk/top-5-best-outdoor-cat-houses/

    Add a porch to the house, letterbox into porch. Airtightness still intact.
    We faced the same issue and went for a Mefa box: www.me-fa.com/product/letter-111/

    They have quite a nice range generally and the slot is large enough for a slim amazon-style book delivery whilst still being too thin to get a thieving hand in without unlocking

    As implied above though, most of our mail now comes in a much larger format, so you may also want to consider an outdoor toolchest or similar hut that acts as a 'safe place' for parcels.

    (Mefa also do parcel boxes but I suspect they are pricy)

    This, assuming it is do-able at your property. Additional benefit is of course that you have an "airlock" between the house and the outside world, which makes a huge difference when opening the front door in the winter!

    We have an external wall-mounted letterbox that works well. As well as letters it can accept small parcels such as paperbacks. Ours is supposedly stainless steel but there are still rust marks developing so next time I might get a powder-coated one. For bigger parcels we just have a wooden box on the porch, so sometimes we get parcels put in there and other times they're left on top and in some cases the courier actually rings the bell and delivers the parcel! But we're in a fairly low crime area and are at home most of the time, so aren't so concerned about security.

    Our porch is just an open covered area to keep the rain off. I was originally going to have an enclosed porch but was persuaded it isn't necessary in a PH, and more difficult to make because there's less heat leaking into it to stop condensation.

    We have an airtight catflap, from Canada IIRC, that opens into an unheated storage room and then another catflap to the outside that reads the cats' chips to control entry. Most importantly, it's transparent. The cats are happy to use that one but not so happy about the airtight one, which isn't transparent. They prefer to have their staff open a door for them :sad:
