Translation: 
In the construction of that city could be seen the full scientific knowledge and architectural skill of Viśvakarmā. There were wide avenues, commercial roads and courtyards laid out on ample plots of land; there were splendid parks, and also gardens stocked with trees and creepers from the heavenly planets. The gateway towers were topped with golden turrets touching the sky, and their upper levels were fashioned of crystal quartz. The gold-covered houses were adorned in front with golden pots and on top with jeweled roofs, and their floors were inlaid with precious emeralds. Beside the houses stood treasury buildings, warehouses, and stables for fine horses, all built of silver and brass. Each residence had a watchtower, and also a temple for its household deity. Filled with citizens of all four social orders, the city was especially beautified by the palaces of Śrī Kṛṣṇa, the Lord of the Yadus.
Purport: 

Śrīla Śrīdhara Svāmī explains that the state highways (rathyāḥ) were in front and the secondary roads (vīthyaḥ) behind, and between them were courtyards (catvarāṇi). Within these courtyards were surrounding walls, and within the walls stood golden residences, atop which shone crystal watchtowers crowned with golden pots. Thus the buildings were multistoried. The word vāstu indicates that the houses and buildings were constructed on ample plots of land, with plenty of room for green areas.
