Key Takeaway
Most Hampshire homeowners assume they need a fully qualified architect to extend their home. The reality is more nuanced — and understanding the difference could save you thousands.
The Architect Assumption
When a Hampshire homeowner decides to extend their property, the first call many make is to "an architect." It's an understandable instinct — the word carries authority and professionalism. But in the context of residential extensions, it can also lead homeowners to pay significantly more than necessary, or to work with a practice whose core expertise lies in commercial or new-build projects rather than the specific world of householder planning applications.
This guide explains the real distinction between architects and architectural designers, what actually matters when commissioning extension drawings in Hampshire, and how to choose the right professional for your project.
Architects vs Architectural Designers: What's the Actual Difference?
The title "architect" is legally protected in the UK under the Architects Act 1997. Only individuals registered with the Architects Registration Board (ARB) may call themselves architects. Many ARB-registered architects are also members of the Royal Institute of British Architects (RIBA), which requires additional continuing professional development and ethical commitments.
An architectural designer or architectural technologist is not legally permitted to use the title "architect" but can legally and competently design extensions, produce planning drawings, prepare building regulations packages, and manage planning applications — the complete service required for a residential extension.
The critical point: local planning authorities do not require drawings to be prepared by a registered architect. They assess planning applications on their design quality, compliance with policy, and impact on the surrounding area — not on the qualification of the person who prepared the drawings. An application prepared by a competent architectural designer with deep local knowledge will typically achieve exactly the same outcome as one prepared by an RIBA architect.
What Hampshire Build Is — And What We Are Not
Hampshire Build is an architectural design practice founded by Mark Eden, with over 25 years of experience in the residential design and build industry across Hampshire, Surrey, Berkshire, and beyond. We specialise exclusively in residential extensions, loft conversions, and garage conversions.
We are not a RIBA-registered architectural practice. We are experienced, insured architectural designers who have handled hundreds of projects across Hampshire's planning authorities — Winchester City Council, Basingstoke and Deane Borough Council, Eastleigh Borough Council, Test Valley Borough Council, New Forest District Council, and the South Downs National Park Authority.
Our 98% planning approval rate reflects the depth of our knowledge of these specific local authorities' requirements — not a generic familiarity with planning law, but precise, detailed knowledge of what each council's planning officers expect, where the sensitivities lie, and how to design an extension that sails through rather than getting stuck in correspondence.
What the Design Process Looks Like With Hampshire Build
Every project begins with a complimentary consultation — either by phone or video call — where we discuss your ideas, confirm the planning route (permitted development, Prior Approval, or full planning application), and provide a no-obligation fixed fee for the work.
From there, the process is:
- Measured site survey: We visit your property and take detailed measurements of the existing house and garden, confirming dimensions, levels, drainage, and neighbouring context.
- Draft drawings: We produce initial planning drawings for your review. These show the proposed floor plans, elevations, and roof plan. We refine these based on your feedback — revisions are included in our fixed fee.
- Planning submission: Our Pre-Build and Premium packages include full management of your planning application, including submission, correspondence with the planning authority, and any negotiation required to achieve approval.
- Building regulations: Our Premium package adds full building regulations drawings, structural coordination, and a pre-build pack — everything your contractor needs to start on site.
Frequently Asked Questions
Is Hampshire Build a qualified architect?
Hampshire Build is an architectural design practice with 25+ years of industry experience. We are not a RIBA-registered architectural firm. We are experienced, insured designers who specialise in residential extensions across Hampshire — a distinction that allows us to offer significantly better value than traditional architectural practices whilst delivering the same planning outcomes.
Do planning departments require a qualified architect?
No. Local planning authorities in Hampshire and across England accept planning applications prepared by any competent designer. The application is assessed on its merits — design quality, policy compliance, and impact on the area — not on the qualification of the person who prepared the drawings. There is no legal requirement to use a registered architect for a residential extension.
What should I look for in an extension designer in Hampshire?
Experience with your specific local planning authority is the single most important factor. Look for: a demonstrated track record of approvals in your area, a fixed-fee pricing structure that protects you from cost escalation, professional indemnity insurance, and clear communication about the planning route your project will take. Ask to speak to recent clients in similar properties.
What professional indemnity insurance does Hampshire Build hold?
We hold professional indemnity insurance appropriate to our practice. We are happy to confirm our insurance position during the initial consultation.
The Right Choice for Most Hampshire Extensions
For the vast majority of residential extensions in Hampshire — a kitchen extension in Winchester, a loft conversion in Basingstoke, a garage conversion in Eastleigh — an experienced architectural design practice like Hampshire Build will deliver exactly the same planning outcome as an architectural firm, with faster turnaround, fixed fees, and specialist local knowledge.
RIBA architects bring genuine added value for complex projects: listed buildings requiring specialist conservation input, large-scale new-build developments, or projects where the client wants a high level of creative design input beyond the planning process. For a typical Hampshire extension, the premium is rarely justified.
