Derbyshire and the Peak District predominantly, with regular projects across the wider East and West Midlands, and a number of clients in Jersey, Channel Islands.

Most extensions and all new-build homes need either planning permission or, in some cases, a Lawful Development Certificate confirming permission isn't needed — which applies depends on scale, location, and whether the property is listed or in a conservation area. Standard applications carry an 8-week statutory determination target; Studio Harrison handles the application itself as part of the design service, not as a separate add-on.

It means treating the building's fabric — insulation, airtightness, glazing, thermal bridging — as the foundation of energy performance, before adding renewable technology on top. It's the same principle behind Passivhaus and AECB standards, and it tends to outperform a less efficient building with solar panels bolted on, both on comfort and on long-term running cost.

From initial consultation to a full set of construction drawings is usually several months, shaped mostly by how quickly decisions get made at each design stage; planning determination then adds a further 8 weeks for a standard application once it's submitted. Larger or listed-building projects, or anything needing pre-application advice, typically run longer.

The investment is usually structured either as a percentage of the construction cost or as a fixed fee for each design stage, agreed upfront once the scope is clear — there’s no “one size fits all”. Our architectural fees are quoted honestly and transparently, based on the scope, complexity and requirements of your project.

The first conversation is free, with no obligation. It’s an opportunity to understand what you’re looking to achieve, establish the likely scope of work and explain the fees involved before you decide how you’d like to proceed.

Yes — a design-led inspection of a newly built home before or shortly after legal completion, checking construction quality and finish against the specification and building regulations, with a written & photographic report of anything that the developer needs to put right. It draws on the same technical training used in design and construction detailing, rather than a generic survey or checklist.
