Buying split level house Pennant hills

Hey guys we are looking at this split level house (930 sqm land with around 220sqm internal, 1980 brick veneer house) in pennant hills. half level down there is a rumpus ( with access to the courtyard), ground level a dinning room, bedroom, bathroom, kitchen, half level up a lounge ( with access to the courtyard) and another half level up 2 bedroom, retreat area and master room suites. We found that the lounge is a bit small but still acceptable. We are worried split level house has impact on the property price. We guess the price may go up to 1.18 milan auction . Any comments are welcome :)
