Compare like for like
Compare the same design stages
One fee may cover planning drawings only while another includes technical design, tendering and site support. Compare scope before comparing price.
- State the project budget and what you want to achieve, not only the room dimensions.
- Ask which design stages, applications and revisions are included.
- Clarify structural engineer, surveyor and specialist-consultant costs separately.
- For heritage property, mention listing or conservation-area status from the start.

Croydon planning and heritage context
Twenty-one conservation areas and several Article 4 directions can materially change the planning route
Croydon has 21 conservation areas where planning controls can be tighter, plus Article 4 directions that remove specified permitted-development rights in particular locations and for certain uses. The council also requires planning permission for conversion to a small HMO in Croydon, so the exact address and intended use should be checked early.
Conservation-area status changes the planning baseline
Croydon Council says planning permission is more likely to be needed where work affects a conservation area and confirms there are currently 21 such areas. An architect should therefore check the property and its setting before relying on ordinary permitted-development assumptions.
Article 4 directions remove permitted-development rights in specific Croydon situations
Croydon Council lists Article 4 directions affecting locations including Chatsworth Road, The Waldrons, Kenley Aerodrome and other areas, and separately states that planning permission is required to convert small properties into HMOs in Croydon. The exact address and project type therefore matter before the design brief is fixed.

Architects covering Croydon
Architects may cover Croydon by project type, planning complexity and postcode. Example areas include:
Central CroydonSouth CroydonPurleyCoulsdonThornton HeathSouth NorwoodNorburyAddiscombe
Start with the property's planning constraints
A standard extension in Thornton Heath and alterations to a heritage property in Central Croydon, Purley or one of the borough's conservation areas can require very different survey and consent work.
Check the address before fixing the design brief. Ask the architect to identify conservation-area, Article 4, listed-building, tree and flood or drainage constraints early enough to shape the proposal rather than redesign it later.
How it works
Describe the project once, then compare Croydon architects
Budget, site, design ambition and required stages help architects decide whether the project fits their practice.
Set out the project brief
Add the postcode, property type, intended changes, budget and any known planning or heritage constraints.
Hear from suitable architects
Up to three interested Croydon architects can respond.
Compare service stages
Check relevant experience and compare exactly which surveys, drawings, applications and construction-stage services are included.
Before you hire
What should you check before hiring an architect?
Relevant project experience and a clearly defined service are more useful than comparing headline percentage fees alone.
Compare similar project experience
Look for work with a similar property type, planning context, budget and technical complexity.
Define the service stages
Agree whether the appointment stops at planning or continues through technical design, tender and construction support.
Clarify other consultants
Ask who appoints structural, measured-survey, party-wall or specialist consultants and whether their fees are separate.
Questions
Architects in Croydon: common questions
Useful answers before you post the job.
How many conservation areas are there in Croydon?
Croydon Council currently lists 21 conservation areas across the borough.
Can an Article 4 direction affect permitted development?
Yes. Article 4 directions remove specified permitted-development rights, so work that is normally permitted may need planning permission in an affected location.
Do small HMO conversions need planning permission in Croydon?
Croydon Council states that planning permission is required to convert small properties into HMOs in the borough.
Can I post a small planning-drawing job?
Yes. The category can cover feasibility, measured surveys and householder planning work as well as larger projects.
Do I have to hire an architect who responds?
No. Up to three interested local professionals can respond and there is no obligation to hire.
