Is it grammatically correct?

Hello Everyone:

Can you please tell me if the following passage (written in third-person omniscient PAST) is correct or not:

"They were all built at the same time, of same color, layout and design. They were five white giant cubes capped with grey rooftops. Standing equally spaced from each other they formed an arc enclosing a lawn. Theirs was the house on the summit, the only occupied house. The remaining houses were two on each limb of the arc, facing each other with their balconies and brown wooded doors and windows. The arc was surrounded by a giant garden except the north where the lawn becomes continuous with a vast arid ground."

Thanks

Thanks a lot. I have made some changes and will greatly appreciate your feedback. I understand grammar alone is not going to do much so please feel free to give feedback about the style as well.

" This part of the city which eventually came to be known as Gulshan in fact had no name. Gulshan, a town of around thousand homes, finished at the end of the road with a boys and girls school standing at its opposing ends. From there going south, starts the dirt road punctuated with neem tress on both sides. After two miles where it ends, on its left side laid the arc of five houses.

They were all built at the same time, of same color, layout and design. Five, white, three story giant cubes capped with grey rooftops. Standing equally spaced from each other they encircled a shared lawn. The house on the summit, the only occupied house belonged to Mr. Intizar. The remaining houses were two on each limb of the arc, facing each other. Each had its own patio made of white and grey marble. The arc was circled by a brief green patch which had made its way between the houses. Beyond the patch, the houses were surrounded by a huge garden for almost a mile in all directions except the north. When crossing over to the other side it obliterated the dirt road completely".
