Architectural Design

Creative, Compliant, and Client-Focused Residential Design

At Arch One, we specialise in residential architectural design that’s as practical as it is inspiring. Whether you’re planning a home extension, loft conversion, full renovation, or a new-build project, our goal is simple: to turn your ideas into spaces that feel like home—while ensuring they’re fully compliant with local planning and building regulations.

We work closely with homeowners, developers, and self-builders across the UK, offering end-to-end design services that guide your project from initial concept to construction-ready plans. Our focus is on creating thoughtful, well-designed homes that respond to your lifestyle, maximise space and light, and enhance long-term value.

What We Offer

At Arch One, we prepare and submit comprehensive architectural package that ensure full compliance and provide everything your builder needs to construct safely and legally.

Bespoke Design Solutions

Every home is unique, and so is every client. We take the time to understand your needs, vision, and how you live—creating tailor-made designs that reflect your personality while remaining functional, efficient, and buildable.

Planning Expertise

Navigating the UK planning system can be complex. As part of our architectural design service, we manage the entire planning application process on your behalf. From pre-application advice to full submissions and liaising with local authorities, we ensure your designs are realistic, compliant, and well-prepared.

Full Technical Drawings

Our team prepares detailed architectural drawings that not only bring your vision to life but also meet all building regulation requirements. These plans form the basis for construction, cost estimation, and contractor engagement—giving you the clarity and confidence to move forward.

Extensions, Conversions & New Builds

Whether it’s adding a new kitchen extension, converting an unused loft, or building a home from scratch, we have the experience to design across a wide range of residential project types. No matter the scale, we approach each project with the same care, creativity, and attention to detail.

The Architectural Design Process

Arch One’s Design Process

We understand that starting a building or renovation project can feel overwhelming—but it doesn’t have to be. At Arch One, we’ve developed a clear process designed to take the stress out of design and planning. From your first ideas to ready-to-build plans, we’re with you every step of the way.

Measured Survey

Every successful project starts with accuracy. We begin by carrying out a detailed measured survey of your property. This gives us a precise understanding of your existing space and forms the foundation for all future design work—removing any guesswork from the equation.

Tailored Design

This is where your vision starts to take shape. We create thoughtful, practical designs that reflect your needs, style, and aspirations—while making the most of your space and budget. We’ll collaborate closely with you to ensure the design feels just right.

Planning Application

Planning doesn’t need to be a headache. Our team handles the entire application process for you, preparing and submitting all necessary documents, liaising with your local council, and responding to feedback to help secure approvals with minimal delays.

Building Regulations

Once planning is approved, we prepare the technical drawings and documentation needed to meet all building regulation requirements. These detailed plans ensure your project is structurally sound, safe, and fully compliant—so you’re ready to move forward with construction.
