We are looking into buying our first home. Due to budget constraints and already having two children (with a third on the way!

) we are kind of restricted to properties that require work which are of a suitable size and within our budget.
Basically, we have found a house that we consider perfect for our needs but will also need to do alot of renovation throughout. The house was previously lived in by an old lady who sadly has recently died. the interior decor and such has nt been touched in at least 15 years if not longer
This is great for us becuase it just us the opportunity to build it up to our standard and put our own mark on it.
the questions i have are:
This is the current layout of the house
as you can see, there are lot of off built in cupboards and such.. and the second front door leading to the utility room is rather odd and unhealpful to say the least..
what we propose is this:
which in theory gives us a much more usable living space and at the same time doesn't reuire too much structral work.. The only Load bearing walls i can see (from the plans and viewings etc) is the wall between the kitchen and Utilty room, and the additional front door from the utility room.
The others are all single brick cupboards.
Our plan would be to remove the cupbaords throughout, change the central heating to a Combi Boiler system (situated in the loft, exisiting boiler is a back boiler in the living room chimney and a hot water cylinder in Bedroom 2 Cupboard). also we would seal up the exisiting back door from the kitchen and turn the living room window into some french doors etc.
aside from the expected replacement plumbing and electrics throughout i would also like to 'network' the entire house for any future upgrades that we may carry out AV wise etc.. would i be best running ethernet cabling to each room from a centrally located hub (i.e. under the stairs) or otherwise.. without spending thousands of pounds in the process.
I am confident that we are able to do alot of the work ourselves except the removal of the load bearing wall, double glazing, gas works and the full rewire but we have friends who are able to do this for us (builders and tradesmen etc)
Any bodu have any suggestions?
We havent purchased the house yet as its a sealed bids type auction but due to its price and expected return for just basic works, we have been advised that its not able to privide a suitable return for an investment purchase so our main competitors are just other FTB's.....
