Question about enclosure for my retic

[waf]

Hello everybody!
I will appreciate any help with this question...
I have a female retic who is about 11.3 ft and 11 kg. I have to build her a larger enclosure by now, so, if she will met the 22 ft in a future, the eclosure need to be around 11-14 ft lengh. I keep my snakes (3 boas and this retic) in a small room... so, the larger wall in there, is only about 9 ft lengh, now, in order to meet the 14 ft, l have to make the enclosure like an "L" (the 9 ft on the larger wall, then, turn over the smaller wall, for the other 5 ft)

My question is: Is it convinient for my retic to build the eclosure like an "L" or it need to be the 14 ft straight...??

Thanks............
