This is what we are planning on doing
1) Extend the entrance area / hall, and move the entrance door. We would like a small bathroom in this area, a larger entrance area, note that we are 5 people, so we need a wardrobe that takes this into consideration. Also, we would like a bigger laundry room. Have a look at the drawings with comments for more details (pdf-document). Note that we really like to have more height between floor and roof in particular where the main entrance / hall is today, and this area should be very good for that?
2) Lift the roof / new floor. Today the roof angle is very steep, thus we have a very small loft, and the angle extends into the living room something that makes the living room walls of not much use. We want the loft to have a private bathroom with both a bathtub and a shower (for mom and dad), maybe a sauna connected to it, one bedroom / walk-in-closet, and some small space for work - one idea here is also to have some open space down to look down onto the floor below (facing towards the kitchen?). It is also important to have windows facing towards the sea, I want to be able to take a bath and browse the ships roll by :-). Note that while both me and my wife tend towards a modern style, I probably like flat roofs better than my wife - drawings should maybe comprise those considerations a bit ;-). It would also be nice to be able to walk out of office and/or bedroom onto a porch facing towards the sea (see inspirational links - and in particular the green / plants and the combination of wood / glass in the outdoor banister, very nice!).
3) Living room / kitchen. More windows, much more windows! Kitchen pipes needs to stay approximately where it is today, but ideally just be able to walk straight from kitchen out to outdoor area through some big glass doors (this is where the porch is today. The porch should probably be bigger and have partly an area with "roof" or similar - we get a lot of rain and snow in Norway. Note that living room can be extended by 75 centimeter (end of cement wall) facing towards where the porch is today.
4) The basement floor - today, two of the rooms are storage. We are going to move that storage area to the entrance area. Thus, the only thing we want in the basement is a bathroom (where it is today, no need for change, it has been renovated) three bedrooms of similar size (for the boys) and a small "living-room / TV / play / homework" - area. That area should be where the largest bedroom is today, as we will have entrance to the garden from the room. The basement can also be extended 75 centimeter. See drawing for details.
The challenge is to remodel and extend the house, but at the same time keeping the "structure" of the old house to keep costs down. The house is built around two cement walls as foundation, and we should keep them as they are today. Both the basement and the living room (facing towards where the porch is today) can be extended 75 centimeter as the walls today has 75 centimeter to reach the end of those walls - see drawing for further details.
The house also has a fantastic view today, and we want to take advantage of that. Incorporating some green design elements would be nice :-).
Today, the house has 4 floors (sort of! - counting the entrance as a "floor"), from the entrance you either go down to the basement, or up the the living room, and further from the living room to the loft. We think that particular structure needs to stay. Changing this will considerably increase the cost of the project.
Note that the chimney pipes can not be removed, and we would like a modern fireplace in the living room, possibly a small / compact fireplace in the loft somewhere too.
We both love a modern style (modern nordic I guess - (not with steep roofs). We would like the facade to have wood siding - "malmfuru" (I think the English word is "ore pine", or something similar). That is, no painting, no maintenance. Could be combined with concrete. Have a look at these pictures for a taste of the wooding: http://www.moelven.com/no/Produkter-og-tjenester/Wood-Prosjekt/Malmfuru/
Also, we are thinking that the kitchen floors should be large tiles or polished cement (just some thoughts)...the kitchen need a side-by-side refrigerator/freezer.
Note, the bathroom in the basement need to stay where it is (also the bathroom window) and is not included in the design. It was so old and ugly we had to quickly renovate it.
