i think ts should reconsider
1. the size - maybe build a semi-d with the extra 10' land on one side
2. seriously do a cost estimate taking into consideration all the fiiting because i think for 250k u will be lucky to even get a 'low cost bungalow' which is not something u would want and regret later. believe me a decent looking bungalow will set you back triple that budget. i just did major reno to my semi-d and it cost me 300k with just extension to kitchen (18X10), other work is just replacing tiles, sinks, toilet bowls, windows, painting, lighting, koi pond(26k), wiring, plumbing, grill, cabinet. The concrete work alone cost 55k, the finishing is just above average, not top grade sumore
