The Portsmouth listing covers 8 units on Western Road. Units run from 5 m² to 72 m² with a median of 24 m², making Portsmouth a small-suite market for practices of three or four people rather than for teams.
Portsmouth is built on Portsea Island, which constrains its office stock more than most English cities of its size — there is little room for business parks, and most commercial space sits within the existing urban grain. Western Road lies in the northern part of the island near the M275 approach, convenient for staff arriving by car from Fareham and the mainland.
With a 72 m² ceiling, this listing serves small firms — marine services, consultancies, professional practices — rather than the naval and defence contractors, who occupy dedicated sites. Portsmouth & Southsea and Portsmouth Harbour stations both run to London Waterloo in about ninety minutes. Each card shows floor area, floor and the asking rate per m² per year.
