I would pick one of the colours out of the bricks. I think lighter rather than darker so the house doesn't look top heavy. When you factor in the whole cost of the extension, paying a colour consultant could be well worth the money. I have added a single story cladded extension to my brick house. The colour consultant was well worth the money. For me, I didn't want it to look like I was pretending the cladding was brick, so went for a colour that complemented the brick rather than blending in. A lot of new houses have cladding bumpouts included in the new build as a feature, I think this is a good look that you could go for. The extension as a feature rather than try to disguise it.

This Two Storey house was designed by StudioMarioRenzi using Insulated Foam blocks and panels. We worked closely with the owners to get the most effective design. The simplified form of the external walls enabled them to construct the IFB walls by themselves. With our assistance we help them to construct a home that is very unique. Hats off to the two of them, they did a fantastic job! Internal view External view

Thank you. The level of insulation provided by ICF construction depends on the type of ICF system is used and the thickness of insulation, but it is often greater than R3. In Australia the insulation levels achieved in ICF construction is in the range of R3 to R6 . We used the 203mm foam blocks that gives an overall width of around 225mm.

there are numerous Sydney based building companies that offer a KDRB service and many that offer display homes that can provide an excellent starting point for house plans that can be modified to suit.. check websites that have designs (with prices) identified by width of block, size of house (50 squares=465sqm) number of bedrooms, bathrooms and garages for suitable houses and ask for quotes based on your specific site and be prepared for much more than you expect but probably less than the cost of a house needing major renovations that doesn't meet your needs.. and of course you could hire an architect to achieve a truly custom designed home but a few tips would be to obtain a proper site plan showing exact length of all your boundaries, direction of north, locations of services, a detailed contour diagram showing the precise levels of your land and contact local council to find out the maximum size house that can be built on your block and any restrictions for height or easements
