I think the words to 'My cellmate thinks I'm sexy' are apt - can't print too naughty.

Was that two "braincells" now Prof?    (asks innocently and ducks for cover)

lol @ proff, we all have senior moments but we aren't daft yet!

Thank you Mlady Raka and Prof for your responses!
I'm actually a "she," and the house we're building is detached. The reason for the two numbers with a dash is because we've got over an acre of land and have been issued 3 house numbers, so the way to do it here (Australia) is to combine all numbers.
For example, we've been issued house numbers 35, 37 and 39 and so it goes 35-39 (the dash is "through" so to speak). A person down the road from us has house number 1-5 (1,3 and 5 been issued).
We actually have the choice of picking one of the house numbers and just using that, but i personally don't prefer what any of them come down to: 8, 1 or 3. I prefer a 2 house since we're a couple with a 6 mo old baby and want a tranquil environment to raise our growing family.

I know that the house number is not the be all and end all, that the occupants have a bearing on the "vibes" of the house as well.  But i think that with what we want from a house (a sanctuary) the 2 house is great.
What do you think?

Dear Milady Fender, (winks)

I feel in this case you should go with your instincts.  Since the adjoining properties which are now merged to one property also belongs to you, and there is no residue energy of other occupants, you should be able to pick whatever combination numbers you like.  I believe the two properties you are combining to get to your number '2' will just resonate with you "more" as being yours.  

The third property which is now included in your property will perhaps always feel as a kind of detached section, unless your actual house was built on the excluded number in which case all three properties will resonate well with you. (The two adjoining properties because of their combined numbers you are using as your address, and the numerical excluded property because your house is built on it.)

Whatever numbers you combine, will enhance your address with the strength of that number.

love and rainbows
