Introduction: The Evolving Art of Home Extensions

Home extensions continue to be one of the most rewarding ways to enhance both the value and liveability of your property, and across Essex, Suffolk, and East London, they remain a top choice for homeowners looking to adapt rather than relocate.

But the way we live, and therefore the way we extend, is changing...

As lifestyles evolve, families are seeking more light, flexibility, and sustainability in their spaces

The modern home extension isn’t just about adding square footage; it’s about designing a space that enhances daily life and connects seamlessly with the outdoors

At DJJ Projects, we’ve seen these shifts first-hand across countless builds, from sleek kitchen extensions in Chelmsford to countryside garden rooms in Suffolk

Here’s our breakdown of the key design trends shaping home extensions in 2025 (even though we're almost in 2026!!)

Open-Plan Living: The Heart of the Modern Home

The open-plan concept isn’t new, but its popularity continues to grow evolving from a design trend into a lifestyle choice

Why it’s so popular

Open layouts promote togetherness

Families want to cook, dine, and relax in one cohesive space rather than being divided by walls

For Essex homes in particular, where kitchen extensions are among the most common projects, open-plan design adds both functionality and flow

Modern variations

• Zoned open-plan layouts: Subtle divisions created with half-walls, changes in flooring, or ceiling height to define spaces without closing them off

  
  

• Broken-plan designs: Partial separation using glazed partitions, shelving, or internal screens for acoustics and privacy

  
  

• Multifunctional islands: Serving as cooking, dining, and social hubs all in one

  
  

Pro tip:

Think about acoustics early, open-plan doesn’t have to mean echoey

The right finishes (like timber floors, rugs, and soft furnishings) can make large spaces feel warm and comfortable

Bi-Fold and Sliding Glass Doors: Bringing the Outside In

No modern extension is complete without a strong connection to the garden and bi-fold or sliding glass doors are the defining feature that achieves this

Why homeowners love them

These expansive glazed doors flood the interior with natural light, create a sense of openness, and allow spaces to transform seasonally

In the summer, the boundary between home and garden disappears; in winter, high-performance glazing keeps the warmth in while maintaining beautiful views

Current trends

• Slimline aluminium frames for a sleek, contemporary aesthetic

• Corner or wrap-around glazing to maximise visibility and daylight

• Motorised or automated systems for effortless operation

  
  

DJJ Projects insight:

We’re seeing growing demand for frameless sliding systems and roof lanterns to complement rear extensions, especially where clients want a “glass box” feel without compromising thermal performance

Sustainable Materials and Energy Efficiency

Sustainability is no longer a buzzword.. it’s an essential part of building design

Essex homeowners are increasingly aware of the environmental impact of materials and construction methods

Eco-conscious design choices

• Reclaimed or locally sourced brick and timber reduce carbon footprint while adding character

• Natural insulation materials (like sheep’s wool, cork, or hemp) improve indoor comfort and air quality

• Triple glazing and airtight construction enhance energy efficiency, cutting long-term heating bills

• Green roofs and solar panels are becoming popular in flat-roof extensions for added biodiversity and cost savings

  
  

Planning perspective

Many local councils in Essex and East London actively support eco-conscious projects

Designing with sustainability in mind can strengthen planning applications and future-proof your property against upcoming energy regulations

Garden Integration and Outdoor Living Spaces

Post-pandemic, homeowners have rediscovered the value of outdoor living

Extensions are increasingly designed not as add-ons, but as transitional spaces that link home and garden

How this looks in practice

• Extended patios and decks directly aligned with interior flooring for level access

• Outdoor kitchens or dining areas that continue the interior design aesthetic

• Covered verandas or pergolas offering shade and year-round usability

  
  

In coastal or countryside areas of Suffolk and Essex, this indoor-outdoor lifestyle trend is particularly strong, merging the comforts of inside living with the serenity of natural surroundings

Design tip:

Opt for large-format tiles or composite decking that flow seamlessly from the interior to the exterior

This continuity enhances space perception and creates an effortless, high-end look

Smart Home Integration

While not always visible, smart home technology is fast becoming an integral part of modern extension design

Popular integrations include:

• Smart heating & lighting systems that adapt to usage patterns

• Automated blinds or skylights for daylight and privacy control

• Integrated sound and security systems for convenience and peace of mind

  
  

When installed during the build phase, these systems are discreet and future-ready, helping homeowners manage energy use and enjoy next-level comfort

Minimalist Aesthetic, Maximum Function

The shift toward clean lines, calm colour palettes, and clutter-free interiors continues into 2025

But minimalism doesn’t mean empty, it’s about intentional design

Examples we’re seeing:

• Hidden storage walls to maintain clean visual lines

• Matte finishes in neutral tones (off-white, clay, stone) paired with warm wood accents

• Simple yet elegant architectural detailing, like shadow gaps and recessed lighting

  
  

This design language complements both modern builds and traditional homes, particularly popular in Essex’s mix of Victorian terraces and contemporary detached houses

FAQs

Q: Do design trends actually increase property value?

A: Absolutely

Open-plan layouts, sustainable materials, and quality glazing not only enhance lifestyle but also boost market appeal, making your property more desirable to future buyers

Q: Can I combine multiple trends in one project?

A: Definitely

Many of our clients blend several, for example, a sustainable open-plan kitchen-diner with bi-fold doors and smart controls

The key is cohesive design and thoughtful material selection

Q: Are sustainable materials more expensive?

A: Not necessarily

While some eco-products carry a small premium, they often reduce long-term running costs saving on energy bills and maintenance

Q: How long does a home extension take in Essex?

A: A typical single-storey extension takes around 10–16 weeks, depending on size, design complexity, and weather conditions

Always factor in design, planning, and lead times for materials
