Yes, let's have an English Parliament alongside a UK one if the Scots vote "No"

There is no need for the English Parliament to be anywhere other than in our nation's capital and in Westminster. Here's how it would work. The House of Commons (the chamber) would house both the UK and the English Parliaments. The UK Parliament would legislate on UK matters - i.e Foreign policy and those other matters NOT delegated to the English, Scottish, Welsh and NI legislatures. Obviously we need to work out what is and what isn't devolved but if we apply the principle of "subsidiarity" we won't go far wrong. The English Parliament would act in exactly the same way as Holyrood, etc.

The UK Parliament would comprise members elected on an identical basis across the UK. Equal sized constituencies. 

The English Parliament would comprise English MPs only (obviously). No Scots (etc.) would vote on English matters (anymore than English MPs would vote in Holyrood). There would be no restriction on English candidates standing for election to both the UK and the English Parliaments if they want to. Similiarly an MSP could also be an MP in the UK Parliament.

Oh and the House of Lords ? Tow it onto the Thames Estuary and sink it.
