I am unsure about “encrespados” in the third which I have translated as “curling towards..”

Any suggestions for improvement would be more than welcome!

Thank you all so much!

Original Spanish (from Spain)
¿Qué hacemos en una parcela tan compleja como esta? Nos encontrábamos inmersos en un mar de dudas ante una parcela con una gran pendiente y complicada para encajar espacios y volúmenes.

Se optó por diseñar y ejecutar un edificio en el cual la ** estructura portante de pantallas ** y losas de hormigón se adaptan a la complejidad del terreno y cuya forma escalonada en vertical proporciona un aumento de la superficie de cada planta superior.

Los volúmenes irregulares, colocados sin seguir ninguna regla, avanzan **encrespados** hacia el horizonte, ganando espacio en cada planta.



My attempt: English (American English, please)
What do we do with a tract of land as complex as this one? We were (immersed/steeped) in a sea of doubt dealing with such an expanse (of land) set on a steep slope, making it complicated to design around the available and usable space.

We opted to design and construct a building in which the supporting walls/barriers and the concrete slabs are adapted to the complexity of the land, and whose graded vertical form provides an increase in floor space in each succeeding upper floor.

The irregular volumes, placed haphazardly, move forward **curling ** towards the horizon, gaining space on each floor.
