ARCHITECTURAL DESIGN SERVICES
House Conversion Architects in Guildford
Reimagine what your home can be with bespoke conversions designed to make the most of every square metre.
At GRK Architecture, we work with homeowners across Guildford to turn unused or outdated spaces into practical, inspiring parts of your home. Whether you’re creating a peaceful garden-view office, a home gym in the garage, or an extra bedroom for a growing family — we’ll help make it happen.


Transforming Underused Spaces Into Places You Love
Planning a home conversion in Guildford often means working with Guildford Borough Council and other local planning bodies — something we’re highly experienced with.
We’ll guide you through the design and approval process with clarity and confidence, helping you understand what’s possible, what’s required, and how to get your ideas off the ground. Every conversion we design is tailored to your lifestyle, space, and future plans.
Conversions in Guildford
A great conversion starts with a conversation. We take the time to learn how you live, what isn’t working, and how your home can grow with you.
Whether you’re based in a Victorian terrace in the town centre or a more rural property in the Surrey Hills, we’ll help you unlock its full potential. Our experience with Guildford Borough Council means we’re equipped to handle every planning detail with precision.
Garage Conversions
Give your unused garage a new purpose — from an office or studio to a spare bedroom. It’s a smart way to add space without the need to extend.
Barn Conversions
We transform barns into beautifully modern homes or multi-use spaces, blending original character with modern design and comfort.
Loft Conversions
Whether it’s a dormer or hip-to-gable design, we’ll create a bright, usable space that enhances your home’s value and lifestyle.
Basement Conversions
Short on space above ground? We’ll help you reimagine your basement into something special — like a cinema room, home gym, or guest suite.
Every Detail Taken Care Of
A successful conversion isn’t just about great design — it’s about making the process smooth from start to finish. We handle all the essentials behind the scenes, from securing planning approval to preparing technical documentation your builders can rely on.
Whether your home is in central Guildford or near a conservation area, you can count on us to keep everything on track.

Planning Permissions
We manage the full planning process and help you understand what’s achievable under local rules. Whether you need a Permitted Development Certificate or full planning permission, we’ve got it covered.

Architectural Designs
Every design is crafted specifically for your home — complete with detailed plans and immersive 3D visuals so you can explore the space in full before a single brick is laid.

Technical Documentation
We produce the construction-ready drawings, building regulation documents, and technical specs needed to ensure the build goes ahead with precision and confidence.

Planning and Regulations Made Simple
Converting a space isn’t just about aesthetics — it’s about unlocking potential and making your home work better for you.
In and around Guildford, planning rules can be complex — especially if your property falls within Guildford Borough Council jurisdiction or near protected areas like the Surrey Hills AONB. From Class Q agricultural conversions to listed buildings, projects often require expert guidance.
That’s where we come in. As experienced residential architects, we combine creative design with a deep understanding of planning policy. Whether you need Permitted Development approval, full planning permission, or simply want to explore what’s possible, we guide you through it — clearly and carefully.
Our aim is to make the entire process straightforward and tailored specifically to your Guildford property and personal goals.
