If your home no longer works for your lifestyle, moving isn’t always the right answer. A well-designed house extension can create the extra space you need while improving how your home works day to day.
However, many homeowners feel overwhelmed by planning permission, building regulations, budgets and knowing where to begin. Previous extensions, drainage, neighbouring properties and even the existing roof structure can also affect what is realistically possible.
At Architectural Vistadesigns, we make the process straightforward. From the first ideas through to planning approval and building regulations, we provide clear advice, practical designs and support at every stage.
What Makes a Great House Extension?
A successful house extension isn’t simply about creating as much extra floor space as possible. The best designs improve how the whole home works; considering the layout, natural light, connection with the garden and how the new space relates to the existing property.
It also needs to be realistic. Budget, planning requirements, roof design, neighbouring properties and how practical the extension will be to build can all influence the right solution.
Sometimes that means extending less rather than more. Thinking through these factors at the design stage can help avoid unnecessary redesigns, delays and unexpected costs later.
“Big is not always better.”

The cost of a house extension depends on its size, design, specification and the existing property.
At the early design stage, we can provide general guidance to help you understand whether your plans are realistic for your budget. However, a more reliable construction cost normally requires the design to progress further, with detailed drawings and structural information available for builders to price.
Not every house extension requires a full planning application. Some extensions can be built under permitted development rights, but this depends on the property, the proposed design and any previous extensions that have already been added.
We assess this at an early stage and explain which planning route is likely to apply before the design progresses.
There is no single timescale for every house extension. It depends on the complexity of the design, how quickly the design is agreed, whether planning permission is required and whether any site or planning issues need to be resolved.
We guide you through each stage, from the initial consultation and measured survey through to design, planning where required, and building regulations, so you know what needs to happen before work can begin.
The drawings required depend on the project and the approvals needed.
We normally start with a measured survey of the existing property, followed by existing plans and elevations and then proposed design drawings. If planning permission is required, we prepare and submit the relevant planning drawings. Once the design has progressed, we can also prepare the more detailed drawings required for building regulations and coordinate with a structural engineer where necessary.
Every property is different. The existing layout and roof structure, previous extensions, planning requirements, available garden space, neighbouring properties, drainage and nearby trees can all influence what is practical.
Your budget is also an important part of the design process. Sometimes the right solution is not the largest possible extension, but one that gives you the space you need while remaining practical to build and realistic for your budget.
Looking at these factors early helps us identify potential constraints and develop the most appropriate design for your home.
Yes. We can guide you through the process from the initial design through to the relevant approvals.
Where planning permission is required, we prepare the drawings, submit the application and manage the planning stage. We can then prepare building regulations drawings, work alongside structural engineers where required and help ensure the necessary information and approvals are in place before construction begins.
The first consultation is about understanding both your home and what you want to achieve.
We’ll discuss your ideas, priorities and budget, look at the existing property and consider any obvious design, planning or site constraints. If you’re not sure exactly what you want, that’s fine too — part of our role is to help you explore the options and decide on the best way forward.
