Off-plan residential development website with live availability: cost

The verdict in three sentences

For a 180-unit off-plan tower in Dubai or a London scheme, a dedicated site with live availability and interactive floor plans sells better than a portal listing, because it keeps buyers on your own path until they book a viewing at the sales gallery. Developers there pay agencies 25,000 to 70,000 USD in Dubai or 20,000 to 60,000 GBP in London for this scope, while the Kolonell grid starts at 1,220 to 5,340 EUR for the website, or 3,810 to 6,100 EUR when the availability grid becomes a small application linked to your sales pipeline. The metric that matters is cost per reservation, not traffic.

What buyers want to see before they visit

An investor comparing off-plan launches in Dubai Hills, Business Bay or Jumeirah Village Circle, or a London buyer weighing schemes in Nine Elms or Canary Wharf, wants four answers: price per square foot, available sizes and views, handover date and the payment plan. In Dubai, they also want to see the RERA project number and confirmation that payments go into a registered escrow account. Bury those answers in a 12 MB PDF brochure and they call three competing developers first.

An off-plan site is built around one tool: the availability grid. Each unit shows floor, type, size, view, price or price band, and a current status (available, on hold, reserved). One click opens the dimensioned floor plan, and a button offers a slot at the sales gallery or a video call.

Dubai sites usually run in English and Arabic, often with Russian or Chinese for target investor groups. London schemes aimed at Asian buyers may add Mandarin. Extra languages are scoped in the quote according to your buyer mix.

Budget: local agency, freelancer or Kolonell grid

The price gap comes mostly from the availability grid. A static list is updated by hand and goes stale within two weeks. A grid linked to the sales team's pipeline stays accurate and justifies a larger budget. Market figures are 2026 estimates.

The item most often forgotten is visual production: CGIs, clean dimensioned plans and site photos. If the architect supplies usable plans, 5 weeks is realistic. Redrawing 30 unit types adds 2 to 3 weeks.

Cost per reservation: dedicated site versus portals

Developer packages on Property Finder and Bayut in Dubai, or Rightmove and Zoopla in London, typically run at 3,000 to 8,000 USD or GBP a month in 2026 for premium placement. They bring volume, but the same enquiries also see your competitors on the same page. A dedicated site fed by targeted campaigns captures exclusive leads and tracks every step.

The site does not replace portals in month one. It complements them, then lets you cut the least profitable packages once tracking shows where reservations come from.

Mini case study

Omar, sales director of a developer in Dubai, has to sell 180 apartments averaging 900 sq ft at 550 USD per sq ft, around 495,000 USD per unit and 89 million USD in total sales. He invests 30,000 USD in a dedicated site with a connected availability grid and 7,500 USD a month in advertising.

Over 12 months, the site generates 40 reservations. Acquisition cost: (30,000 + 90,000) / 40 = 3,000 USD per reservation, or 0.61 % of a unit price. Portals alone, at 5,000 USD a month, had produced 14 reservations at 4,286 USD each. The 26 additional reservations secure about 12.9 million USD of extra sales in the year.

FAQ

Should prices be shown on the site?

Showing a price band per square foot, for example 450 to 650 USD, filters out-of-budget visitors and raises the viewing rate. Exact unit prices can stay with the sales gallery if the sales director prefers.

How long until the site is live?

Allow 5 to 8 weeks if plans and CGIs are ready. A short launch version, home page and registration form, can go live in 2 weeks for the pre-launch campaign.

Who updates the availability grid?

The sales team, from a simple back office or a synced spreadsheet. Weekly updates at the very least avoid showing units that are already reserved.

Does the site need regulatory information?

In Dubai, showing the RERA project number and escrow details is expected by serious buyers. In London, clear information on leasehold terms, service charges and the building safety status is just as important.

One site per project or one developer site?

A site per project converts better during the 18 to 36 month sales period. The developer site then showcases track record and points buyers to the next launches.
