Website design and development built for conversion
Founders and product teams choose NexaPhaze when the website must do more than look polished. Industry benchmarks show that a one-second delay in load time can cut conversions by up to 7%, and over half of mobile sessions abandon a page that takes longer than three seconds. We design around those realities from day one.
Every engagement starts with positioning, information architecture, and a conversion map — then moves into a reusable design system and production-ready front-end. The result is a site your team can extend without rewriting the foundation.
- Conversion-led UX and clear information architecture
- Bespoke design systems with intentional motion
- Next.js engineering with headless CMS handoff
- Core Web Vitals tuned for Lighthouse 90+
How we ship marketing websites
We use a discovery-to-launch pipeline: strategy workshop, wireframes, high-fidelity UI, componentised build, CMS training, and performance instrumentation. Typical marketing sites ship in 3–5 weeks without sacrificing craft.
Performance is non-negotiable. We ship with next/image, font subsetting, edge caching, and structured metadata so search engines and AI answer engines can parse your offering clearly.
Related capabilities
A website rarely stands alone. Many clients pair website design with our branding and digital identity work for a coherent system, or layer AI automation to qualify leads and route enquiries after launch.
When product depth is the goal, we connect the marketing site to SaaS and web app development so acquisition and product share one design language.

Contact NexaPhazeFrequently asked
How much does website design cost in London?
NexaPhaze website projects typically start from mid four figures for focused marketing sites, scaling with scope, CMS complexity and motion. After a short discovery call we provide a fixed-scope proposal so pricing stays clear.
How long does a website redesign take?
Most redesigns take 3–5 weeks from kickoff to launch. Larger multi-locale or CMS migrations may run 6–8 weeks. Timeline is confirmed in discovery against your content and stakeholder availability.
Do you build sites on WordPress or Next.js?
We specialise in Next.js with a headless CMS for speed, security and editorial flexibility. We can migrate content from WordPress and keep editors productive without compromising Core Web Vitals.
Will my new website be SEO-ready?
Yes. Every NexaPhaze site ships with semantic HTML, metadata, sitemap and robots configuration, Open Graph tags, and performance budgets that support organic visibility from day one.
Can you improve an existing site instead of rebuilding?
Absolutely. We audit UX, performance and technical SEO first, then recommend a targeted refactor or a full rebuild — whichever delivers the stronger ROI for your stage.
