If your home has stopped fitting the way you live, a well-built extension is usually the answer, and it does not have to mean moving. From a single storey kitchen-diner to a full double storey addition, a rear extension, a wraparound, or a side return that reclaims a wasted alley, TD Property Renovations builds property extensions of every kind across Widnes and the surrounding areas. This guide walks through the main types, how to tell which one suits your house, and what a good build looks like from first drawing to finished room.
Extensions Built Around Your Home, Not a Template
No two houses need the same extension. A Victorian terrace with a dark galley kitchen has different options to a 1930s semi with a wide plot, and both differ again from a detached home with room to grow in more than one direction. That is why we start every job by looking at the house and how you actually use it, rather than reaching for a fixed design. The right extension is the one that solves the problem you have, whether that is more living space, an extra bedroom, a brighter kitchen, or a home office that finally has a door.
Family-run and hands-on for over 25 years, we build across Widnes, Liverpool, Runcorn, Warrington, St Helens, and the wider North West. The same team handles the structure, the trades, and the finish, so the standard stays consistent from the footings to the last coat of paint. Every property extension we take on is designed around your home and signed off properly.
The Main Types of Extension We Build
Most projects fall into one of a handful of shapes. Here is the plain-English version of what each one does, so you can start to picture which suits your home before we ever visit.
1Single storey rear or side extension
The classic ground-floor addition, ideal for a bigger kitchen-diner, a family room, or an open-plan living space that opens onto the garden. The most popular choice for a reason.
2Double storey extension
Space added over two floors in one build, so you gain a larger room downstairs and an extra bedroom or bathroom above. Often the best value per square metre when you need bedrooms as well as living space.
3Wraparound extension
A side and rear extension combined into one L-shaped footprint, transforming the whole back of the house into a wide, open living and dining space in a single project.
4Side return infill
Filling the narrow, wasted alley down the side of an older terrace or semi and joining it to the kitchen, turning a cramped galley into a bright open-plan room without losing garden.
Beyond these, we also build porches, garage conversions, and garden rooms where a full extension is not the right fit. The point of the list is not to sell you the biggest option, but to find the one that gives your home what it is missing. If you already know the direction you are leaning, our dedicated guides on side return infills and wraparound builds go deeper on each.
Which Extension Suits Your Home?
The right choice comes down to what you need, the shape of your plot, and your budget. The table below is a quick way to match the common goals to the extension that usually delivers them, but it is a starting point, not a rule. On a site visit we weigh it all up against your actual house.
A good builder will tell you honestly when a smaller build does the job, or when spending a little more now avoids a second project later. That advice is only worth anything when it is based on your home, which is why we never quote an extension blind.
What a Well-Run Extension Looks Like
Whatever the shape, a good extension follows the same disciplined sequence, and the quality lives in the parts you cannot see once it is finished.
1Design and drawings
We agree the layout, the light, and the spec on paper first, so there are no surprises once the build starts.
2Foundations and structure
Footings, steels, and any RSJs are engineered and signed off by building control, never guessed. This is where a build is made or broken.
3Shell, roof, and glazing
Walls, roof, and any rooflights or bifold doors go in to get the space weathertight and full of daylight.
4Fit-out and finish
Plastering, flooring, kitchen or bathroom, and decoration turn the shell into a room ready to live in.
The structural steel that opens up the plan is the heart of most extensions, and getting the glazing right at the drawing stage is what separates a space that dazzles from one that disappoints. Both are part of the building services we bring to every job.
Planning, Permitted Development, and Party Walls
Many single storey extensions fall under permitted development, meaning no full planning application is needed, but this is never a given. Double storey builds, conservation areas, flats, and homes where permitted development rights have been removed usually need a full application. The Planning Portal sets out the size and height limits, and they are worth checking before drawings are finalised.
Building regulations apply to every extension, covering the structure, insulation, drainage, and glazing, with sign-off through building regulations approval. Where a build sits on or near a boundary, the Party Wall Act comes into play and notices need serving in good time. We manage the planning, the regulations, and the party wall side so none of it lands on your desk.
Extension Cost: Where the Money Goes
Cost depends far more on what goes into the extension than on its footprint alone. The structure, the glazing, and the kitchen or bathroom fit-out are where the money concentrates, and a fixed-price quote from a proper site visit is the only honest way to know your number.
The honest advice is to price the structure, glazing, and groundworks properly up front, get a written specification, and hold a contingency of around ten per cent for what the ground might reveal. After 25 years across Widnes, Liverpool, Runcorn, Warrington, and St Helens, we know where the awkward bits of an extension tend to hide, whichever type you choose.
Why Summer Is the Time to Start
An extension means part of the house is out of action for a stretch, so timing the build for the warmer months makes the disruption far easier to live with. The drier weather keeps the groundwork and roof stages moving, and a temporary kitchen or a bit of outdoor cooking is a good deal more pleasant in summer than in the depths of winter.
Starting the drawings and any party wall notices now means the shell can be weathertight before the wet autumn, with the finished space ready to enjoy going into winter. If more room has been the dream, the settled summer weather is the moment to get the project moving.
Frequently Asked Questions
What types of extension does TD Property Renovations build?
We build the full range: single storey rear and side extensions, double storey extensions, wraparound extensions, and side return infills, along with porches, garage conversions, and garden rooms where those suit better. Rather than push one type, we look at your home and how you live in it, then recommend the extension that solves the problem you actually have across Widnes and the surrounding areas.
Which type of extension is right for my house?
It depends on what you need and the shape of your plot. A bigger kitchen usually points to a single storey rear extension, extra bedrooms to a double storey, opening up the whole back of the house to a wraparound, and a dark galley kitchen in an older terrace to a side return. We weigh it all up at a free site visit and tell you honestly which option gives the best result for your budget.
Do I need planning permission for an extension?
Many single storey extensions fall under permitted development and need no full application, but this is not guaranteed. Double storey builds, conservation areas, flats, and homes where permitted development rights have been removed usually need a full planning application. We check your specific situation at the design stage and handle any application needed, so you know where you stand before anything starts.
Which areas do you cover?
We are based in Widnes and build extensions across the surrounding areas, including Liverpool, Runcorn, Warrington, St Helens, and the wider North West. Being local means we know the housing stock, the local planning authorities, and the ground conditions, which helps a project run smoothly from the first drawing to the finished room.
How long does an extension take to build?
It varies with the type and size. A single storey or side return extension often runs eight to twelve weeks on site, while a double storey or wraparound takes longer because there is more structure and floor area involved. We give a realistic programme with the quote so you know what to expect, and we keep you updated at each stage rather than leaving you guessing.
Does an extension add value to my home?
A well-designed extension is one of the strongest value moves you can make, because it adds the space buyers most want without the cost and upheaval of moving. The gain usually justifies the spend, and the daily benefit of a home that finally works for the family is bigger still. Good design rather than sheer size is what makes an extension pay.
