London Borough of Croydon
Architects in Croydon
A RIBA chartered practice based in Dulwich, working across Croydon. A borough of two halves: dense mixed-use development in the centre and generous suburban plots to the south.
Architects working across Croydon
Croydon spans a wide range of project types. The north and centre are urban and mixed-use, with a strong pipeline of residential development. The south, through South Croydon, Purley, Sanderstead, Coulsdon and Shirley, is suburban and green, with detached and semi-detached houses on plots big enough for substantial extensions and replacement dwellings.
We work across both. Marjoram Architects is a RIBA chartered practice with its studio in Dulwich, designing extensions, whole house renovations, one-off houses and residential development. Every commission starts with a free initial consultation and a scope shaped around your scheme, budget and programme.
Planning in Kingston
Local knowledge of the planning route
Croydon's policy differs sharply between the urban centre and the suburban south. We establish which context your site sits in and what that means for scale and density before design work begins.
Conservation and constraints
Protected areas and green belt edges
The borough contains conservation areas, protected trees and green belt land at its southern edge, and some areas carry Article 4 directions. We confirm the designations affecting your property up front.
Common Project Types
Extensions, new houses and development
Large rear and two-storey extensions and loft conversions in the suburbs, whole house renovations, replacement dwellings and back land plots, plus residential and mixed-use development schemes.

Common questions
Working with Marjoram in Croydon
-
Yes. We design residential, mixed-use and commercial schemes across the borough, including South Croydon, Purley, Sanderstead, Coulsdon, Shirley, Addiscombe and the town centre. Every project starts with a free initial consultation.
-
Yes. Alongside private house projects we work with landowners and developers on infill, back land and mixed-use schemes. The focus is on unlocking value in underused land while keeping the scheme deliverable through planning. We test density and massing against local policy before design work begins.
-
Everything from a single-storey extension to whole house renovations, one-off houses and multi-unit residential and mixed-use schemes. We are a small studio, so the people you meet at the outset are the people working on your project throughout.
-
Fees are agreed in writing before we start and are set against defined work stages, so you know what each stage covers and what it costs before committing to it. The right structure depends on the size and type of project, and we set out the options at the initial consultation.
-
Once an application is validated, householder and minor applications are generally determined in around eight weeks, and larger schemes in around thirteen. Design work and preparing the application come before that, so it is sensible to allow several months from first meeting to decision.
-
We visit the property, discuss what you want to achieve, and set out the likely planning route, the scope of work involved and a realistic budget. There is no obligation to proceed.
