Chalet Bungalow & Building Plot In Bedford - £155k

This is looking like a massive bargain if it can be picked up for the guide price of £155,000. Looking at it on google maps the plot definitely seems big enough for another property:

I really think there's good money to be made here, will be interesting to see what it goes for at auction. A quick search reveals it's been on the market for £190k (https://www.onthemarket.com/details/1306068/) and hasn't sold, so now it's up for auction with a guide price of £155k.
