Loft Conversions in Bexley & Kent
Unlock Your Loft Space with a Trusted Family-Run Builder
A loft conversion is one of the smartest ways to add extra space to your home without sacrificing your garden or going through the stress of moving.
Whether you’d like a new master bedroom with en-suite, a quiet home office, a playroom, or a guest suite, a well-designed loft conversion can completely transform how you use your home.
With property prices rising across Bexley and Kent, many homeowners are choosing to convert unused attic space rather than relocate – gaining the rooms they need while significantly increasing the long-term value of their property.
At P J Dunbar Builders Ltd, we’ve been carrying out high-quality loft conversions for over 30 years, helping families across Bexley, Bexleyheath, Dartford, Sidcup, Eltham, Welling, Orpington and wider Kent make the most of the space they already have. From simple rooflight conversions to larger dormer and hip-to-gable lofts, our experienced team handles everything from planning and structural work to the final finish.
Types of Loft Conversions We Build
Every property is different, and the right loft conversion depends on your roof shape, head height, budget, and how you want to use the new space. We’ll assess what’s possible, explain your options in plain English, and recommend the most suitable design for your home and goals.
We can work with your architect’s drawings or introduce trusted architectural and structural specialists to help develop a design that is both practical and compliant with planning and building regulations.
Benefits of a Loft Conversion
A loft conversion can do far more than just add another room. Done properly, it can transform how your home feels and functions – and make a meaningful difference to your long-term plans.
With demand for property strong across Bexley and Kent, a professionally built loft conversion is one of the most reliable ways to increase both living space and resale value.
Create Valuable Extra Living Space
Whether you need an extra bedroom, a peaceful home office, a playroom for the kids, or a private guest suite, a loft conversion gives you the room you’re missing – without needing to move home.
It’s an ideal solution for growing families, multigenerational living, or simply creating a more comfortable, flexible home.
Increase the Value of Your Property
Well-designed loft conversions can add significant value, especially in sought-after areas like Bexley, Bexleyheath, Dartford, Sidcup, and surrounding parts of Kent.
By adding an additional bedroom or bathroom – particularly a master suite – you make your home more attractive to future buyers and often move it into a higher price bracket.
Avoid the Cost and Hassle of Moving
Moving home comes with estate agent fees, legal costs, stamp duty, removal costs, and the stress of finding the “right” property in the right area.
Converting your loft lets you stay in the location you love, keep your existing garden and neighbours, and gain the extra space you need without the disruption of relocating.
Make Better Use of Wasted Space
For many homes, the loft is simply used for storage – or not used at all.
A loft conversion unlocks this wasted area and turns it into a warm, comfortable, fully usable part of your home, often with some of the best views and natural light in the house.
Modernise and Improve Energy Performance
A loft conversion is the perfect opportunity to upgrade insulation, improve ventilation, and install modern glazing.
This can help make your home warmer in winter, cooler in summer, and more energy efficient overall – reducing draughts and improving comfort.
Design a Space That Works Now and in the Future
From long-term guest accommodation to a quiet workspace, your loft can be designed to fit your current lifestyle and future plans.
Whether you’re working from home more often, planning for teenagers needing extra space, or thinking ahead to resale value, a flexible loft layout gives you options for years to come.

Our Loft Conversion Process
With over 30 years of experience, we’ve developed a clear, structured process that keeps your loft conversion running smoothly from the first conversation to the final sign-off.
Whether you’re in Bexley, Bexleyheath, Dartford, Sidcup, Eltham, or elsewhere in Kent, our approach is designed to minimise stress, maintain communication, and ensure quality at every stage.
Free Consultation & Initial Advice
We start with an informal chat about your ideas, property, and goals. We’ll discuss how you’d like to use the space, what type of loft conversion might be suitable, and any initial planning or structural considerations. This is simply a chance for you to ask questions and for us to share honest, experience-based advice.
Site Survey & Feasibility Assessment
If you’d like to move forward, we carry out a detailed survey of your loft and roof structure. We’ll check head height, access for a staircase, existing layout, and assess how best to support the new floor and roof changes. At this stage, we’ll also flag any planning, building control, or structural points relevant to your home in Bexley or Kent.
Design, Drawings & Structural Calculations
We can work with your existing architect or introduce trusted architectural and structural partners. Together, we’ll develop detailed plans that cover layout, staircase positioning, roof alterations, window locations, and all key details. We also arrange structural engineer calculations where required to ensure the loft is safe, compliant, and built to current standards.
Planning Permission & Building Regulations
Many loft conversions fall under permitted development, but some require full planning permission – especially where roof shapes are being significantly altered or in certain areas.
We’ll guide you through what applies to your home, handle permitted development checks, and manage planning applications and building control approvals where needed.
Pre-Construction Planning
Before work begins, we’ll finalise specifications, confirm materials and finishes, agree timelines, and outline how the build will be phased. You’ll know exactly what to expect, when key stages will happen, and how we’ll manage access and disruption within your home.
Construction & Quality Control
Our experienced team then carries out the construction work – from structural steelwork and floor joists to dormers, insulation, windows, plumbing, and electrics. A dedicated project lead oversees the build, keeps you updated, and ensures every stage is completed safely and to a high standard of workmanship.
