How Much Does a House Extension Cost in Torquay & Paignton in 2026?

If you are thinking about extending your home in Torquay or Paignton in 2026, the first question is usually the same: what is it likely to cost? The honest answer is that extension pricing varies quite a lot from house to house, especially across Torbay where plot shape, access, levels, views and the age of the property can all affect the build. As a rough guide, many homeowners start with broad budget ranges rather than a single figure, then refine them once the design, specification and structural approach are clearer.

In practical terms, a straightforward single-storey extension in Torquay or Paignton might typically start from around £2,400 to £3,200 per square metre, while more complex or higher-spec schemes can rise beyond that. A two-storey extension may look better value on a square metre basis for some homes, but overall costs are often higher because of added structure, roofing changes, stair alterations and more extensive internal works. Those figures are only rough guides, and they usually exclude wider renovation items, landscaping, professional fees and furnishings.

What shapes the cost most?

The biggest cost drivers are usually the things you do not fully see on an early sketch: foundations, drainage, steelwork, insulation requirements, glazing, roof form and how the new space connects to the existing house. In parts of Torbay, sloping sites, tighter access or older buildings can also affect labour time and logistics. Then there is specification. A simple family room extension with standard finishes will sit in a different budget bracket from a kitchen extension with large sliding doors, rooflights, bespoke joinery and premium flooring.

The type of property matters too. Around Torquay and Paignton, housing stock is mixed, and many homes have quirks that only become clear once measured surveys and early investigations are done. Detached homes may offer easier side access for materials, while terraced or closely spaced properties can require more careful planning of deliveries, scaffolding and neighbour considerations. If the house needs significant upgrading at the same time, that can shift the budget from “extension only” to a broader reworking of the home.

Typical extension budget ranges in 2026

As a rough guide, a modest single-storey extension could typically fall somewhere around £60,000 to £95,000, depending on size and finish. A larger kitchen-diner extension, particularly one with structural openings into the existing house and a more design-led specification, might often land in the region of £90,000 to £160,000 or more. Two-storey extensions can vary even more widely, but many homeowners in Torbay find that overall project budgets often begin around the low six figures once all related works are included.

It is also worth remembering that build cost is only one part of the overall picture. Architectural design, structural engineering, planning support where needed, building regulations, surveys, party wall matters if relevant, kitchen supply, flooring, decorating and external works can all sit outside an initial contractor estimate.

Planning, design and local context

Whether you need planning permission will depend on the size and form of the extension, the position on the plot and the status of the property. Some projects can fall within permitted development, while others need a full planning application. In conservation areas or on more sensitive sites, there may be extra considerations. As with any project in Torquay, Paignton or wider Torbay, it is best to check the current position with the local authority rather than rely on assumptions from similar houses nearby.

Good design can make just as much difference to value as the size of the extension. In many homes, the aim is not simply to add floor area but to improve flow, light and the relationship with the garden. Sometimes that means a carefully considered rear extension; in other cases it may involve reworking the ground floor layout so the whole house functions better. Our approach to house extensions is to balance architecture, buildability and budget from the outset, so the design stays grounded in what is practical as well as what is desirable.

For homeowners comparing options, it can also help to look at completed work in a general way rather than focusing only on headline square metre rates. Thoughtful renovation shows in how new ideas are joined to existing character — the approach we bring to all of our renovation work. Every home is different, of course, but thoughtful detailing, material choices and well-resolved layouts are often what make an extension feel truly part of the house.

How to budget sensibly

A sensible starting point is to set two numbers: your ideal budget and your absolute comfortable limit. Then allow a contingency, typically around 10% to 15% as a rough guide, for the unknowns that can emerge once work begins. This is particularly important in older properties, where hidden drainage issues, uneven structure or the need for extra remedial work are not unusual. Early surveys and measured design work will not remove every surprise, but they do reduce risk and help decisions happen before site costs start mounting.

It also helps to choose a team that can guide you through design, planning, technical detail and construction as one joined-up process. That tends to make budgeting clearer because decisions about structure, glazing, specification and sequencing are considered together, not in isolation.

If you are exploring an extension in Torquay, Paignton or elsewhere in Torbay, the most useful next step is usually a conversation about your house, your priorities and the budget range that feels right for you. From there, it becomes much easier to judge what is achievable in 2026 and where to invest for the best result. When you are ready, you are very welcome to request a consultation.
