Commercial conversion architects that unlock new possibilities in existing buildings.
We combine intelligent design with planning expertise to give existing spaces a new purpose — working through structural constraints, balancing commercial priorities and creating lasting value while guiding your project from first ideas through to completion.
We deliver strategic, value-driven architecture and planning that simplifies conversion projects, reduces risk, and transforms underused buildings into assets built to perform long into the future.
Shaped by the site, driven by the goal
Design & planning to overcome constraints.
Converting a building means making existing space work smarter. Awkward footprints, structural quirks and planning constraints can all shape what’s possible. We identify these early and turn them into informed design decisions, helping you move forward with confidence.
From Article 4 areas to Prior Approval and full change-of-use applications, we tailor our planning strategy to the opportunity. With technical design delivered in-house, we develop proposals that stand up to scrutiny at planning stage and on site.
The aim is fewer delays, reduced risk and a project that’s easier to deliver.
From Potential to Project-Ready
End-to-end conversion planning & design management & clarity.
We handle every step of your commercial conversion in-house — from assessing viability and planning strategy to full architectural design and technical delivery.
Whether you’re converting an office to residential, repurposing a retail unit, or exploring permitted development rights, we bring clarity, speed, and commercial focus to the table.
With GRK, you get a joined-up team that understands how to unlock value from existing assets while navigating planning, design, and delivery with confidence.
How we support your project:
- Site appraisals and conversion strategy
- Change of use planning and prior approval
- Layout design and space optimisation
- Compliance with Building Regulations and design standards
- Drawings and documents for planning and construction
- Navigating local policy and permitted development rights
We manage every from start to finish
Commercial conversion architects who understand the bigger picture.
Every commercial conversion presents its own mix of constraints and opportunities. We bring planning strategy and architectural design together under one roof to help you unlock value from existing assets—whether you’re converting office space to residential or changing use across mixed schemes.
From day one, you’ll work with a dedicated team that understands the pace, complexity, and commercial pressures of repurposing buildings. We act quickly to identify constraints, resolve issues early, and develop designs that meet policy, satisfy planners, and support long-term returns.
With a clear focus on compliance, buildability, and future flexibility, we turn underused spaces into high-performing developments that work—financially, functionally, and sustainably.
It’s a joined-up approach built to support your goals and strengthen your property portfolio.
