Thinking about adding space to your home? Find out what a house extension is, which types suit Bristol properties, whether you need planning permission.
What Are House Extensions in Bristol and Why Are They Worth It?
Bristol is a city with charming housing stock, ranging from Victorian terraced properties in Totter down to semi-detached family houses in Henleaze and Bishopston. While they appear great, their architecture may no longer fit your requirements. Small kitchens, closed-off dining rooms, and no space for the expanding family are common issues. And this is precisely why a house extension Bristol homeowners go for has become the most popular way of improving your home without having to move to a new one. Here you will learn everything about what a house extension means, its types, what regulations should be taken into account, and how to make sure of its durability.
What Is a House Extension?
An extension is a construction project that sees your current property enlarged and expanded through a permanent addition to increase the total living space in your current house. Extensions are normally constructed on the side, at the back or even the top of the property and connected to the old structure to ensure seamless integration with your current living quarters. An extension could be a bigger kitchen, living and dining area, additional bedroom, home office or utility room.
It's easy to see why people love this idea, especially those who have limited space but do not wish to move from their current locations, children’s school or current neighbourhood.
What Types of House Extensions Work Best in Bristol?
It is important to choose the one that suits your land and your garden and your expectations.
Single-storey rear extensions: are most popular. They expand the rear end of the home to the garden space and are perfect for a larger kitchen or family room with big glazed doors.
Side return extensions: take advantage of the small piece of land next to many Victorian and Edwardian terraces. This can turn a small, dingy kitchen into a large, spacious one.
Double-storey extensions: They add rooms on two floors, and thus they are suitable for families that require a larger space and at least an extra room or toilet.
Wraparound extensions: consists of combining a side return and a rear extension, resulting in an open plan at the rear of the house.
Any competent builder is capable of doing all these, starting from the drawing stage to the final snagging phase.
Do You Need Planning Permission for a House Extension?
This is undoubtedly the most frequently asked question. There are a number of extensions that can be built under Permitted Development rights, which means there is no need for a full planning application as long as the extension remains within certain restrictions in terms of size, height and material. The maximum allowable length of the single storey extension to the rear of the semi-detached and terrace house is 3 metres or 4 metres for the detached house without planning permission.
There are less Permitted Development rights in the conservation areas and listed buildings, and these are applicable to some parts of Clifton, Redland and Cotham. The flats and dwellings in which rights have been stripped off require a full application.
Apart from the planning issue, you should also have the building regulations approval, which would include construction, thermal insulation, water disposal and fire precautions. If you build an extension next to a common boundary, you will need a Party Wall agreement with your neighbour. It is much better to sort out all these issues before starting any work.
What Does the Process Look Like?
An effective extension is carried out through a well-organized process that makes everything predictable.
First visit.An expert builds his career by going to your place, checking out your place and then telling you what he thinks of it based on your requirements.
Design and planning.Drawings, structural calculations, and all the planning or permitted development documentation is done. By using a design and build firm, there is just one contract for all of this, meaning that you are not following up with the architect, engineer, and builder individually.
The build. Groundwork and foundations take place first, then the erection of the walls, roof, windows, first fix, plastering, and finishes. An effective site manager will ensure that work progresses and updates you.
Handover.With the job finished, you will tour the work with the builder, and any problems sorted out before the project is completed.
One of the most helpful things you can do when trying to assess the builder is view any completed projects that they have worked on in your area.
How Disruptive Is Building an Extension?
Typically, homeowners stay in the house during the extension process, and it is quite doable with the right crew. The floors have to be taken care of, while tools need to be packed up each day and noisier work coordinated in accordance with your schedule. Temporary kitchen facilities can be useful in case of a kitchen rebuild. Timelines are important as well. It is better to have a contractor promising ten weeks and doing it in ten weeks.
Is an Extension Worth It?
That is true for many people living in Bristol. Relocation comes with stamp duty, commissions to the agent, removal costs, and the difficulty of finding a new house. Extensions allow you to design your house from bristol builders to suit your needs, and a good extension can increase the value of your property. The thing is to find a balance between the size of the construction and the house itself, as well as the surrounding area.
It is also necessary to understand whether it is only an extension that solves your problem. If there is already an unused integral garage where you do not park your car, then garage conversion will help create another room in the house. It might be a bedroom, an office, or even a playroom. Some houses require both types of conversions.
How Do You Choose the Right Builder?
The quality of the extension depends mainly on whom the extension is made by. Some qualities of a quality builder are:
• Fixed quote in writing. Beware of estimates that keep increasing. The quote and the work ensure that you don’t exceed your budget, and any change to the work to be done will have a quote first and then agreement.
• In-house team. That is to say, the carpenters, plasterers and electricians are all employees of the company and not subcontractors.
• Reviews. Get reviews from real people, preferably homeowners in the area and not from the website that looks so impressive.
• Guarantee. Guarantee in writing for the structural construction.
• Communication. The communication goes as far as the construction.
Extension constructions are big jobs. Do not be in haste; compare quotations from other builders.
Final Thoughts
Bristol house extensions that families opt for do not only provide them with more space. What is more important, they build their houses better suited to their needs. It may be a comfortable kitchen where everyone will be able to sit together or a place where one can concentrate on work without being disturbed by anyone else. As long as there is a good plan, process, and team in place, everything can go smoothly.
