The verdict in three sentences
In 2026, a premium redesign of a showcase site for a London architecture practice costs between GBP 9,000 and 22,000, depending on portfolio depth and animation level. The line item that blows up quotes is not the design but the structuring of a filterable portfolio of 40-plus projects, with heavy images to optimise. Budget 8 to 12 weeks of production and an annual maintenance of roughly 15 % of the build to keep the site from degrading.
What a premium redesign really costs
An architecture practice sells an aesthetic: its site must be flawless on mobile, fast, and stage the projects well. Here are the 2026 ranges per line item (order of magnitude, London agency pricing).
| Line item | 2026 range (GBP) | Note |
|---|---|---|
| Discovery + UX + IA | 1,500 - 3,500 | Workshops, wireframes, journeys |
| Art direction + UI design | 2,500 - 5,500 | Desktop + mobile mockups |
| Filterable portfolio (40+ projects) | 2,000 - 4,500 | Filters by type, year, location |
| Build + CMS | 2,500 - 5,000 | Headless or Webflow |
| Core Web Vitals + SEO | 1,000 - 2,500 | AVIF images, lazy-load, LCP < 2.5s |
| QA + go-live | 500 - 1,000 | Cross-device testing |
| Total premium redesign | 9,000 - 22,000 | Depending on options |
Recurring costs also weigh on the decision. A premium showcase site is not a one-off.
| Recurring item | 2026 cost | Frequency |
|---|---|---|
| Cloud hosting (EU/UK) | GBP 40/month | Monthly |
| Domain + SSL | GBP 15/year | Annual |
| Maintenance (15 % of build) | GBP 1,350 - 3,300/year | Annual |
| Local SEO London (option) | GBP 400 - 900/month | Monthly |
| Portfolio updates | GBP 300 - 600/year | By volume |
Freelance, agency or Webflow template: the trade-off
The choice of supplier changes price, timeline and risk. A 2026 London agency day rate sits between GBP 600 and 850, a senior freelancer between GBP 400 and 600.
| Option | 2026 price (GBP) | Timeline | Risk |
|---|---|---|---|
| Adapted Webflow template | 3,000 - 6,000 | 3-5 wks | Little differentiation |
| Senior freelancer | 6,000 - 12,000 | 6-10 wks | Single-person dependency |
| Structured agency | 9,000 - 22,000 | 8-12 wks | Higher budget |
For a firm chasing prestige clients and framework tenders, a template alone quickly plateaus: the identity is too generic. The agency justifies itself as soon as portfolio and SEO become strategic.
Mini case study
James, managing partner of a 9-person architecture studio in London, ran a 2018 non-responsive site with a 4.8s mobile LCP. He invests GBP 14,500 in an agency redesign: a new filterable portfolio of 52 projects, LCP down to 1.9s, and a projects blog. Over 6 months, mobile bounce rate drops from 71 % to 44 %, and he attributes 3 new consultations (one worth GBP 280,000 in fees) to the new site. With GBP 2,100/year maintenance, ROI is reached on the first signed commission.

FAQ
What is the credible minimum budget for a premium redesign in 2026?
Below GBP 9,000, you are looking at a template refresh. A genuine bespoke redesign with a structured portfolio starts around GBP 9,000.
How long does a redesign take?
Budget 8 to 12 weeks from discovery to launch, with 2 to 3 weeks just to gather and optimise project imagery.
Do we need to redo existing SEO?
Yes, a botched migration can lose 20 to 40 % of traffic. Budget GBP 1,000 to 2,500 for redirects and Core Web Vitals work.
Webflow or a headless CMS?
Webflow works up to 40-60 pages and a non-technical editor. Beyond that, or if you want CRM integration, a headless stack (Next.js + CMS) gives more freedom.
Is maintenance mandatory?
Not mandatory but strongly advised: without maintenance, performance and security degrade within 12 to 18 months. Budget 15 % of the build per year.
