Bespoke & Template Themes

We have a wealth of experience and expertise in delivering both entirely bespoke Shopify & Shopify Plus themes designed and built from the ground up from scratch alongside customised templated themes. Bespoke themes give creative teams complete freedom to design and build an online experience that is bespoke, and unique to your business that showcases your products uniquely. Bespoke themes are typically load faster as their code base only contains the exact architecture, features and functionality required to the design and are built using modern practices. The alternative and popular approach to launching new stores on Shopify is to leverage one of the existing premade Shopify themes. Our team will not only help you choose a suitable theme from Shopify's theme library but also make a wide variety of customisations so your ecommerce store matches your branding and offers an engaging customer experience. Bespoke theme projects are a powerful way to stand out in competitive markets and are great for highly custom requirements whilst template projects require lower levels of time and financial investment yet can still achieve admirable results.

Discovery, Strategy & Planning

The initial phase of our Shopify theme projects is the discovery, strategy and planning phase. The goal of the discovery phase is to establish a thorough and objective understanding of the project and define clear strategic goals for growth. Our specialist Shopify web design team conducts a detailed analysis of your brand identity, art direction, logo, colour, previous store and user journey mapping to gain a thorough understanding and foundation to guide the project. We conduct vigorous UX design research and competitor analysis to move forward into design with a breadth of industry understanding. Understanding competition and conducting gap analysis amongst competitors can provide your new store the competitive edge amongst similar businesses. In addition, conduct behavioural analysis leveraging previous analytics, heatmaps and customer feedback reports to propose clear and realistic goals for the project and identify friction & needs in the customer buying journey.

Shopify Theme Design

Engage customers with considered store design.

The second phase of our Shopify theme projects is our design phase. Our creative design team crafts wireframes of each page layout and maps the core customer journey throughout your store. Wireframing helps us to create page layouts that are diverse in content, focus on the goal of the page and prevent distraction by design. In bespoke theme projects, our designers will then proceed to create high-fidelity designs of how the store will visually look when built using the most unique and impactful ideas to create something bespoke to your brand. We also prototype our designs with our collaborative design tools so you can experience how the store will feel once built. For template theme projects, our team will suggest themes to choose from and focus our creative efforts on page layouts, customisations and begin store setup. Placing considerable time into our creative process and a dedicated stage, allows us to craft unique, memorable and growth-centric store experiences our merchants that yield many benefits for your customers and exceed expectations.

FAQs

Shopify Theme Projects

The key advantage of building a bespoke Shopify theme for your e-commerce store, particularly with the help of skilled web designers in London or elsewhere in the United Kingdom, is the ability to create a storefront that fully aligns with your brand’s personality and values. Unlike pre-built templates, which are used by thousands of other businesses, a custom Shopify theme sets you apart, capturing the attention of your target audience with unique elements, graphics, and user experiences tailored to your business needs.

Custom themes offer greater customization of aspects like navigation menus, product pages, and tablet screens, ensuring your storefront is optimized for scalability and traffic growth. By focusing on your specific business operations, a bespoke theme can integrate seamlessly with APIs, ERP systems, and payment solutions, offering a smoother shopping experience for users. Moreover, custom themes prioritize coding best practices, leading to faster pages, fewer errors, and improved security—critical factors when handling orders, payments, and visitor data.

While pre-built themes may have lower prices and faster delivery times, they often come with limitations in creative freedom, functionalities, and adaptability. Pre-designed templates may include features and libraries you don’t need, which can slow down your site and dilute the shopping experience. In contrast, bespoke themes allow you to focus on the specific steps and elements required to meet your business needs, whether it’s migrating from another platform, integrating developer tools, or customizing dashboards to streamline staff operations.

Of course, creating a custom Shopify theme takes pride, hands-on attention, and adherence to industry trends and best practices. It also allows your company to push boundaries and set new standards for your e-commerce store. By building a custom theme, you ensure your storefront not only reflects your brand but also keeps up with the latest tips, tricks, and news in the world of e-commerce, helping you deliver a shopping experience that stands out to thousands of potential visitors.

Ultimately, whether you’re focusing on improving your product pages, scaling your sales, or enhancing public perception with case studies, a bespoke Shopify theme gives you the tools to shape your store’s personality, exceed user expectations, and meet your business goals.

Shopify has over 300 different themes for you to choose from, so it can be quite a task to narrow down your search. We'd advise you to initially narrow your search by aesthetics to create a shortlist of themes that you like the look of. Following this, install the themes as trials into your store, to begin seeing the sections and customisability that the theme has to offer. Remember to explore the different layout options within the theme, as you can often create something very unique using the settings included. Lastly, we would recommend you review the load speed of the theme, to ensure you are choosing a performant and aesthetic choice.

It's important to remember that every theme project is unique and has a custom scope and therefore timings will be different. However, as a general rule for a typical template project - you can expect these projects to take 8 - 12 weeks. For bespoke Shopify theme projects, you can expect these to take around 6 - 8 months.

Absolutely, we support merchants to not only launch bespoke or pre-built template Shopify storefronts but also to migrate to Shopify and Shopify Plus. We have a wealth of experience in platform migrations such as Magento, BigCommerce and WooCommerce. From data export and import to content management and a seamless transition, we have a trusted track record of migrating brands to Shopify.
