A Development Designed for Modern Business

Good commercial space is about more than square footage. It’s about how a space supports the working day — light, efficient floor plates, quick vertical transport, dependable power and security, and an environment that reflects well on the business that occupies it.

Fortis One is planned around exactly that. Office floors are laid out for efficiency and flexibility, suiting everything from a compact consultancy to a full corporate floor. The upper levels enjoy panoramic views across the Nairobi skyline toward the Ngong Hills, while shared rooftop lounge and business-club facilities give teams and clients a considered space to meet beyond the desk. At ground level, three retail floors bring footfall, convenience and a flagship restaurant with outdoor seating into the building itself.

The result is a calm, capable working environment in a genuinely prestigious setting.

Unit Types

Retail Spaces — Ground to Level 2 Three floors of premium retail designed for high-footfall occupiers — branded stores, financial institutions, showrooms, and a flagship restaurant with elegant outdoor seating well suited to business meetings and open-air dining. Pricing on application.

Office Suites — Levels 3 to 18 Meticulously planned office units from approximately 1,200 sq ft, with high-end finishes and efficient layouts. Well suited to corporate headquarters, law and consultancy firms, technology companies and startups. From approximately KES 15,000 per sq ft + VAT — roughly KES 18,000,000 for a 1,200 sq ft suite. Larger contiguous floor plates to be confirmed on enquiry.

Availability: the lower office floors — Levels 3 to 10 — are currently available. Level 11 and above is sold out; we’re glad to register your interest for resale opportunities on the higher floors should they arise.

Signature Penthouse Office — Levels 19 & 20 — Sold Out A single 10,800 sq ft penthouse office, capped with a private rooftop terrace on Level 20 — a rare commercial space ideal for a C-suite leadership floor or an exclusive corporate headquarters. As it sits above Level 11, the penthouse is now sold out; resale enquiries are welcome should it come back to the market.

• Rooftop lounge and business-club facilities
• 24-hour security, CCTV and advanced access controls

Location Advantage

Upper Hill is Nairobi’s primary commercial and financial district — home to major banks, multinational head offices, embassies and blue-chip companies, and the address many of the country’s leading firms choose for their headquarters. Fortis One sits directly opposite the Radisson Blu, placing it among that established cluster with the prestige and day-to-day convenience that comes with it.

The area is well connected to the wider city, and the upper floors enjoy open views across the skyline toward the Ngong Hills. Specific drive times to the CBD, the Expressway and other key nodes can be confirmed at point of enquiry.

Payment Plan

Both instalment and mortgage payment options are available. Office suites are offered from approximately KES 15,000 per sq ft + VAT, with retail spaces priced on application; the detailed instalment and mortgage schedules are shared with the price list and brochure on enquiry.

Please note: every purchase requires a minimum of one parking bay, in addition to the unit price — KES 1,750,000 in the lower basement or KES 2,000,000 in the upper basement. It’s worth factoring this into your budget from the outset, and we’re glad to talk it through.

Why It Works for Owner-Occupiers

For a business buying its own space, this development offers a genuinely strong fit:

• A prestigious, recognisable Upper Hill address among blue-chip neighbours
• Efficient, well-finished floor plates that adapt to your team’s needs
• The certainty and control of owning rather than leasing your premises
• Shared business-club and rooftop facilities for meetings and client hosting
• Modern infrastructure — dependable power, security and high-speed lifts
• Room to grow, with suites from 1,200 sq ft up to larger contiguous floor plates

It’s a practical way to secure a long-term home for your business in a location that carries weight with clients and partners.

Why It Works for Investors

Upper Hill is one of Nairobi’s most established commercial office markets, with sustained demand from multinational and corporate tenants — the kind of occupier pool that values a Grade-A address. For an investor, Fortis One combines that location strength with modern building standards in a limited-supply, Grade-A building; the upper floors and the penthouse have already sold, which speaks to the level of interest in the development.

As general market context (and as estimates only, to be confirmed), commercial space in this part of Upper Hill has typically transacted on lease terms in the region of:

• Base rent: approximately KES 85–110 per sq ft per month
• Service charge: approximately KES 20–22 per sq ft per month
• Parking: approximately KES 8,000–10,000 per bay per month

These are indicative area figures for context only — not a projection or guarantee of rent, occupancy or return for any specific unit. We’d encourage any investor to confirm current market evidence and run their own numbers. We’re glad to assist diaspora and overseas investors with the acquisition and documentation process.
