The verdict in three sentences
An architecture firm sells images and a signature first, so its website is a sales tool, not a brochure. In London in 2026, a bespoke premium redesign costs between 9,000 and 22,000 EUR net depending on how many projects you showcase, versus 3,500-6,000 EUR for an adapted theme. The real metric is not the price but the qualified enquiry rate, which often moves from 1.2% to 2.8% after a well-executed redesign.
What the budget actually covers
The range varies mostly with portfolio volume (30 to 80 project pages), photo/video production, and animation level. Here are the 2026 orders of magnitude seen on the London market.
| Item | Adapted theme | Standard bespoke | Premium bespoke |
|---|---|---|---|
| UI/UX design | 800-1,500 EUR | 3,000-5,000 EUR | 6,000-9,000 EUR |
| Integration & dev | 1,200-2,500 EUR | 3,500-6,000 EUR | 5,000-8,000 EUR |
| Portfolio (30-80 projects) | 500-1,000 EUR | 1,500-3,000 EUR | 2,500-4,500 EUR |
| SEO & content | partly included | 1,000-2,000 EUR | 2,000-3,500 EUR |
| QA & accessibility | 300-500 EUR | 800-1,500 EUR | 1,500-2,500 EUR |
| Total net | 3,500-6,000 EUR | 9,000-15,000 EUR | 15,000-22,000 EUR |
Design is 35-45% of a premium budget: that is where the difference plays out between a generic brochure and a portfolio that makes people want to hand you a tender.
Timelines, maintenance and 3-year total cost
A website underestimates its true cost when maintenance is forgotten. Here is the full 36-month cost, excluding campaigns.
| Element | Adapted theme | Premium bespoke |
|---|---|---|
| Initial build | 5,000 EUR | 18,000 EUR |
| Delivery time | 3-5 weeks | 6-10 weeks |
| Monthly maintenance | 60-120 EUR | 90-180 EUR |
| Hosting/year | 200-400 EUR | 300-600 EUR |
| Agency day rate | 350-450 EUR | 500-650 EUR |
| 3-year total cost | ~9,000 EUR | ~26,000 EUR |
The premium premium pays off if the site generates just two extra projects per year, since the margin on an architecture project far exceeds the budget gap.

Mini case study
Julien, managing partner of a 12-person firm in London, gets 400 visits/month with a 1.2% enquiry rate, i.e. ~5 leads/month. After a premium redesign at 18,000 EUR net, traffic rises to 550 visits and the rate hits 2.8%, i.e. ~15 leads/month. Over a year, +120 qualified leads; at an 8% close rate, that is ~10 extra projects. At an average 6,000 EUR margin per project, the site pays for itself in under 4 months.
FAQ
How much is a premium redesign in London in 2026? Expect 9,000 to 22,000 EUR net for bespoke work, depending on portfolio volume and animation level. An adapted WordPress theme stays possible at 3,500-6,000 EUR.
How long does it take? 6 to 10 weeks for a premium project, including 2-3 weeks of design and 1-2 weeks of QA. Your content readiness (photos, project copy) is the top delay factor.
Do all project pages need rebuilding? No: prioritise 20-30 flagship projects as full pages, the rest in a grid. That cuts cost while keeping the portfolio effect.
What maintenance is needed after launch? A 90-180 EUR/month plan covers security, updates and small improvements. Without it, a premium site degrades within 12-18 months.
How do I measure ROI? Track the qualified enquiry rate and cost per lead, not visit counts. A move from 1.2% to 2.8% alone justifies the investment.
