Chelmsford continues to be one of Essex’s fastest-growing cities, with homeowners increasingly choosing to extend, renovate and remodel rather than move. Whether you’re considering a contemporary rear extension, a loft conversion, a complete home renovation or a new build dwelling, understanding the planning process and appointing the right architect early can make a significant difference to the success of your project.
Connor Ferris Architects is a RIBA Chartered architectural practice based near Chelmsford, delivering residential, commercial and development projects throughout Chelmsford and the surrounding villages. Our role is to guide clients through every stage of the project, from the initial feasibility study and planning application through to Building Regulations, tendering and construction support.

House Extensions in Chelmsford
A well-designed extension should do much more than simply add floor area. It should improve the way your home functions, maximise natural light and create spaces that enhance everyday living.
We regularly design:
- Single-storey rear extensions
- Double-storey extensions
- Side extensions
- Wraparound extensions
- Kitchen extensions
- Garden room extensions
During the design process we carefully consider:
- Orientation and daylight
- Garden connections
- Internal layouts
- Structural constraints
- Future flexibility
- Energy efficiency
Loft Conversions
Many homes across Chelmsford have excellent loft conversion potential.
Depending on the existing roof structure, this could include:
- Rooflight loft conversions
- Rear dormers
- Hip-to-gable conversions
- Full loft remodels
We assess headroom, staircase design, structural requirements and planning constraints before developing the most appropriate solution.
Planning Permission in Chelmsford
Many residential projects can be completed under Permitted Development, while others require full planning permission.
Common planning considerations include:
- Conservation Areas
- Green Belt
- Design and appearance
- Neighbour amenity
- Overshadowing
- Highways and parking
- Heritage constraints
Having experience preparing planning applications across Essex enables us to advise clients on the most appropriate planning strategy from the outset.
Building Regulations
Planning approval is only one part of the process.
Before construction begins, detailed Building Regulations drawings are required to demonstrate compliance with structural, thermal, drainage, fire safety and accessibility requirements.
These drawings also provide contractors with sufficient technical information to accurately price and construct the works.

Frequently Asked Questions
Do I need planning permission for an extension?
Not always. Many domestic extensions fall under Permitted Development, although this depends on the size of the proposal, planning history and location of the property.
How long does planning permission take?
Once validated, most householder planning applications are determined within approximately eight weeks.
When are Building Regulations required?
Almost all structural alterations, extensions and loft conversions require Building Regulations approval before construction.

Yes. We regularly work alongside trusted consultants and can assist with tendering the project to experienced contractors.
