Kitchen Extensions in Bexley & Kent
Create a Bright, Spacious Kitchen Designed for Modern Living
A kitchen extension is one of the most transformative improvements you can make to your home.
Whether you're dreaming of an open-plan kitchen-diner, a larger family space, or a beautifully modern cooking and social area, extending your kitchen can completely change the way you live — giving you more light, more space, and a layout that finally works for your everyday lifestyle.
With rising property prices across Bexley, Bexleyheath, Dartford, Sidcup, Eltham, Orpington, Welling, and wider Kent, more homeowners are choosing to extend rather than move. A well-designed kitchen extension gives you the space you need without the stress and uncertainty of relocating — while significantly increasing long-term property value.
At P J Dunbar Builders Ltd, we’ve been building high-quality kitchen extensions for more than 30 years. As a trusted, family-run builder, we manage every stage of the process from the initial ideas and planning through to construction, glazing, electrics, plumbing, finishing, and final handover. The result is a beautifully crafted kitchen designed around your home, your lifestyle, and your future.
Types of Kitchen Extensions We Build
Every kitchen — and every property — comes with its own potential. We take the time to understand how you use your space, what your home currently lacks, and what layout will offer the best long-term value and practicality. Our team can work alongside your architect or introduce our own trusted design partners to create plans that maximise space, natural light, and flow.
Benefits of a Kitchen Extension
A kitchen extension brings far more than just extra space — it transforms the heart of your home. Below are some of the core benefits homeowners in Bexley, Kent, and South East London enjoy when extending their kitchen.
Create a Light, Spacious, Open-Plan Living Area
One of the biggest advantages of a kitchen extension is the ability to create an open and sociable living space that works for modern family life. By extending into the rear or side of your property, you can design a layout that brings cooking, dining, and relaxing together in one bright, welcoming area.
Homeowners often tell us how much this improves daily routines — whether that’s entertaining friends, keeping an eye on children while cooking, or simply enjoying a better sense of space and light.
With thoughtful design, including skylights, lantern roofs, or large glazing, your new kitchen can feel dramatically bigger and more uplifting.
Increase the Long-Term Value of Your Home
A well-designed kitchen extension is one of the most financially beneficial improvements you can make. In areas like Bexley, Bexleyheath, Sidcup, and Dartford — where open-plan layouts are highly desirable — buyers place huge value on a modern kitchen-diner with improved flow and natural light.
Whether you choose a rear extension, wraparound, or side return, increasing your square footage and modernising your layout can significantly raise your home’s resale value.
Many clients see a strong return on investment, making a kitchen extension not only enjoyable but also a smart long-term decision.
Improve Practicality, Comfort, and Everyday Living
Older homes often have kitchens that feel tight, dark, or disconnected from the rest of the house. A kitchen extension allows you to redesign your layout around the way you actually live — adding more storage, widening narrow spaces, improving flow, and creating zones for dining, cooking, working, and relaxing.
With space for kitchen islands, breakfast bars, utility rooms, or additional seating, you can tailor the design to suit your lifestyle.
Many homeowners tell us their extended kitchen becomes their favourite space in the house and the room they spend the most time in.
Stay in the Area You Love Without the Stress of Moving
Moving home can be stressful, expensive, and disruptive — especially when you already live in an area you love.
Between estate agent fees, legal costs, removals, and the challenge of finding the right property, many homeowners find that extending is a far better alternative.
A kitchen extension gives you the additional space you need while allowing you to stay close to schools, family, work, and your community.
You get the benefits of a bigger, more functional home without the upheaval of relocating.
Got Questions About Planning a Kitchen Extension?
We’re always happy to offer friendly, no-obligation advice if you’re unsure where to begin or want to explore what’s possible with your home.
Our Kitchen Extension Process
With more than 30 years of experience, we’ve refined a smooth, structured process that keeps your project clear, enjoyable, and well-organised from start to finish.
Below is a detailed overview of how we guide homeowners through their kitchen extension journey.
Free Consultation & Early Advice
Every project starts with a friendly, informal conversation about your ideas and budget. We help you understand what’s possible for your home and guide you through the best options. No pressure, no obligation — just clear, honest advice from an experienced local builder.
Detailed Site Survey & Feasibility Assessment
If you’d like to proceed, we arrange a site visit to assess your home, take measurements, and review the layout. This helps us confirm what’s structurally possible, discuss design options, and identify any planning considerations — ensuring your project starts on a solid, well-informed foundation.
Architectural Design & Planning Permission
Once feasibility is confirmed, we move into the design stage. We can work with your existing architect or introduce trusted design partners to prepare tailored drawings. We also manage planning checks, structural calculations, and building control approvals, ensuring everything is in place before construction begins.
Pre-Construction Planning & Scheduling
Before work begins, we confirm all project details, including timelines, materials, and construction stages. We keep everything clear and transparent so you know exactly what to expect, helping the build run smoothly and with minimal disruption.
Construction & Quality Control
Our skilled, long-standing team carries out all aspects of the build, with a dedicated project lead keeping you informed throughout.
We work to high standards, take care in your home, and maintain a clean, safe site from start to finish.
Final Sign-Off, Handover & Aftercare
Once the build is complete, we walk you through the finished space, handle final sign-off, and make sure everything meets our standards. We remain available for aftercare and future work — many clients return to us years later, which we take as the highest compliment.

Kitchen Extension FAQs
The cost of a kitchen extension depends on the size of the build, the type of extension, glazing choices, structural requirements, and the level of finish you’re aiming for.
Rear extensions tend to be more straightforward, whereas wraparound or double-storey extensions involve more structural work and planning considerations.
After a site visit, we provide a clear, detailed, itemised quotation so you understand exactly what’s included — with no hidden fees or unexpected costs along the way.
Most standard kitchen extensions take around 8–12 weeks once construction begins, though larger or more complex extensions can take longer.
The timeline also depends on how much structural alteration is required, whether internal walls are being removed, and the level of finishing work involved.
Before we begin, we provide a clear schedule so you know exactly how the project will progress from week to week.
This depends entirely on the type of extension you choose. Side-return extensions often take up unused alleyway space and hardly affect your garden at all, while rear extensions extend further into the garden but provide more internal space.
During our survey, we’ll help you explore different options so you can choose a layout that balances indoor space with outdoor living.

Many kitchen extensions fall under permitted development, meaning full planning permission may not be required. However, this depends on factors such as the height, depth, and location of the extension, as well as whether your home has been extended previously.
