Types of Home Extensions We Build
Every home and family has different requirements. We build a range of home extensions across Poole and Dorset, designed to complement the existing property while creating practical, comfortable new living space. Whether you are considering a rear extension, side extension, single-storey extension or a larger two-storey project, we can manage the building work from the structural stages through to completion.
Single-Storey Extensions
Single-storey extensions are a popular way to create additional kitchen, dining or living space while transforming how the ground floor of your home works. We build single-storey home extensions across Poole and Dorset, including rear and side extensions designed around your property and requirements.
Two-Storey Extensions
A two-storey extension can create substantial additional space across both floors of your home. These projects can provide larger kitchen and living areas downstairs while creating additional bedrooms, bathrooms or office space upstairs. We manage two-storey extensions across Poole and Dorset, including the structural work and coordination required throughout the build.
Rear House Extensions in Poole
Rear home extensions are an excellent way to create a larger kitchen, dining or living area and improve the connection between your home and garden. We build rear extensions across Poole and Dorset, including open-plan layouts, structural alterations and the associated building works needed to transform the ground floor of your property.
Side Extensions
A side extension can make excellent use of otherwise unused space alongside your property, creating additional living space without necessarily extending far into the rear garden. Depending on your home, a side extension can provide a larger kitchen, utility room, home office or improved open-plan layout. We build side extensions across Poole and the surrounding Dorset area.
Kitchen Extensions
A kitchen extension can create a larger, brighter and more practical heart of the home, with space for open-plan cooking, dining and family living. We build kitchen extensions across Poole and Dorset, including structural alterations and steelwork required to open up existing layouts and connect the new extension with your home.
Structural Alterations & Steelwork
Many home extensions involve more than simply adding new walls. Creating open-plan living spaces, removing internal walls or connecting an existing property to a new extension can require significant structural alterations.
Premier Home Developments can coordinate and carry out structural works as part of your project, including wall removals, structural openings, steel installation and associated building work. Where structural calculations are required, we work with the relevant structural engineer and building control requirements to ensure the work is properly planned and carried out.
From opening up an existing kitchen and dining area to supporting a new extension with structural steelwork, we can manage the construction process as part of the wider project.
Open-Plan Living & Internal Alterations
Removing walls and changing the layout of an existing property can completely transform how a home feels and functions. We can help create larger, connected living spaces while considering the structural requirements, finishes and practical details involved in the work.
Our Home Extension Process
We understand that extending your home is a major project. Our approach is designed to make the process clear and manageable, with each stage planned before work begins and regular communication throughout the build.
1. Planning & Preparation
We discuss your requirements, review the proposed works and establish the scope of the project. Where required, we coordinate with architects, structural engineers and building control before construction begins.
2. Groundworks & Foundations
Once the project starts, we prepare the site and carry out the required excavation, drainage and foundation works in accordance with the design and building control requirements.
3. Structural Construction
We build the extension structure, including walls, steelwork, roofing and structural connections to the existing property. We carefully manage the transition between the existing building and the new extension.
4. First & Second Fix
As the building progresses, we coordinate plumbing, electrical work, insulation, plastering, carpentry and other required trades to keep the project moving efficiently.
5. Finishing & Completion
The final stages bring everything together, including internal finishes and the completion of outstanding works. We work through the agreed scope with you so the finished extension is ready to become part of your home.

How Much Does a House Extension Cost in Poole in 2026?
If you’re considering extending your home, one of the first questions is usually: “How much is it likely to cost?”
Every project is different, but having a realistic idea of budget early in the process can help you make the right decisions before committing to a project.
At Premier Home Developments, we believe in discussing costs openly from the beginning, so you have a clearer understanding of what may be achievable for your budget.
As a general 2026 budgeting guide, a professionally built single-storey house extension in Poole and the surrounding Dorset area may typically cost around £2,500–£3,500 per m² + VAT.
This is intended as an early budgeting guide rather than a quotation. A straightforward extension with good access and a relatively simple specification may cost less, while projects involving substantial structural alterations, large areas of glazing, complex roofing, kitchens, bathrooms or higher-end finishes can cost considerably more.
What Affects the Cost of a House Extension?
The final cost of a house extension depends on several factors, including the size and design, ground conditions, structural steelwork, drainage, access, roofing, glazing, plumbing and heating, electrical requirements and the level of finish.
This is why Premier Home Developments prices projects from the actual drawings, specification and scope of work, rather than relying solely on a generic price per square metre.
Already Have Plans for Your Extension?
If you already have architectural drawings, send them over to us. We can take an initial look at your proposed extension and discuss your plans, priorities and budget.
Don’t have plans yet? That’s fine too. We’re happy to have an initial conversation about what you’re hoping to achieve and the likely next steps.
Home Extension FAQs
How much does a home extension cost in Poole?
The cost of a home extension depends on its size, design, specification and the structural work involved. Ground conditions, finishes, plumbing, electrical work and other requirements can also affect the overall price. We provide a detailed quotation based on the proposed scope of work rather than relying on a generic price per square metre.
How long does a home extension take to build?
The construction time depends on the size and complexity of the extension. Smaller projects may take several months, while larger extensions involving significant structural alterations can take longer. Before work begins, we provide a proposed programme so you understand the expected stages and timescale.
Do I need planning permission for a home extension?
Some extensions may fall under permitted development rights, while others require planning permission. The requirements depend on the size and design of the extension, the property and its location. Read our House Extension Planning in Poole & Dorset guide for more information about planning your project.
Can you carry out structural alterations as part of an extension?
Yes. Many extension projects involve structural alterations such as removing walls, creating larger openings or installing structural steelwork. We can coordinate the required structural calculations and work with building control as part of the wider construction project.
Can I stay in my home while an extension is being built?
In many cases, homeowners can remain in the property during construction, although this depends on the size and location of the works. We discuss the expected disruption with you before the project starts so you can plan accordingly.
Do you manage the different trades involved?
Yes. We can coordinate the different stages and trades required for the building work, helping to keep the project organised from the initial structural work through to the finishing stages.

Our aim is to build long-term relationships with our clients, not simply complete a project and move on.
