Different types of house extensions:
Porches are typically small extensions to the front of a house, although they can be much more extensive and can be built to the side or back. Common examples include simple structures of only brick walls, columns, windows or doors.
Due to size, most porches do not need planning permission, and as long as the porch is isolated from the house by an internal door and not heated, they will not require much paperwork.
Relatively simple structures that are typically made of uPVC, timber or aluminium. Some conservatories need planning permission, and some do not.
A sunroom is a conservatory with regular roof extension types and walls, including lots of glazing. They are durable and warm while also bringing in a lot of light. Due to the costs involved and the fact that they are more complex to build than a wrap-around conservatory, it is desirable to employ both an architectural company and an experienced builder.
Planning permission rules for sunrooms are very similar to those for conservatories. However, building control approval will surely be required.
Single storey side and rear house extension
Single storey house extensions are constructed against a part of the house so that one or more sides of the extension are connected to the home, and there is only the ground floor and any basement built to it. Single storey extensions require building control approval, but they may not need planning permission.
Single Storey Extension can add notable value to your home, and you can turn your home extension into a:
Open plan Living Room
Two storey or multi-storey extension
A multi-storey extension can be constructed to most elevations of an existing building.
A double-storey extension can be used to add a bedroom or bathroom upstairs or even create an open plan living-dining room with dramatic ceiling height.
The impact on neighbours can be much more significant; this can only be built onto detached or semi-detached houses with a suitably sized side plot or garden.
Wrap around house extension
Wrap-around extensions are built by joining a side extension and a rear extension together, forming an L shaped wrap around an existing house.
You should choose to have an open plan wrap around extension to build a beautifully spacious and illuminated area.
An over-structure extension
An over-structure extension is an extension atop an existing structure such as a garage, a living/dining room or kitchen.
A lot of detached and semi-detached houses usually have a single storey side garage. This garage creates a chance for an additional extension on top of it.
The cost of house extension
Side return house extensions are less expensive than single-storey rear extensions. Single storey rear extensions are cheaper than a wrap-around or double-storey extension.
Your taste and requirements will directly affect the total cost of the extension.
The minimum cost is £1,500 per square meter. However, it can go up to £6,000 if you like beautiful things. In some extensions, the glazing cost alone was more than £30,000.
We work across London, Surrey, and the South East.
On average a full refurb of a standard 2 bedroom property will take 6 -8 weeks.
A standard two bedroom property will usually cost around £40k for mid spec finish. Using cheaper kitchens and bathrooms and other materials can bring this down as far as £30k and high spec finishes can be upwards of £100k.

I was so astonished by the work they accomplished every day to the point that the work was finished before the cutoff times. We are certain to recommend Red Builders Building Company to every single customer.
We applied to different companies for quotes and got what we viewed as a reasonable and realistic quote for a genuinely extensive renovation of our home from Red Builders. The project manager and his group worked admirably and exceeded our desires. They included us in the selection process for the property, way to deal with the work and specifications. They were truly flexible and effectively obliged our decisions for additional work. The work has been done to the most professional level in a friendly, considerate and ideal style. Red Builders entire staff was gathered outside of our home ten minutes before the start time. The things that surprised us more than anything was the way that the project manager recollects everything about the details and takes individual liability for ensuring that you, the customer, are totally happy with the work that you need to be done. I have worked with different building organizations on various under takings throughout the long term. Red Builders are most likely the best that I have worked with, and I have no hesitation in suggesting him. Catch him in case you can!
I am writing to thank you for your expertise, knowledge, reliable attitude showed by yourself and Red Builders team to the fruitful outcome of this project. We asked Red Builders to redesign a little flat and, despite the fact that the flat is small, it was significantly difficult to renovate it as it required a detailed renovation. Red Builders performed brilliantly. The Red Builders staff we were in touch with were amazingly capable and pleasant. As in most of such cases with are design, little issues emerged during the remaking period. Red Builders had the option to manage these issues in the most effective and practical manner. The project came in on the financial plan and due to the schedule. They did a wonderful job, and we currently love our flat. When the activity was done, Red Builders kept on following up and disclose things to us about the flat and its equipment after we moved in. I would highly suggest Red Builders.
Kindly pass my gratitude to all engaged with this project.
A little more than a year back, I planned my first renovation project. I had never done anything like this, and after the web research, I sourced 4-5 quotes. I chose to go for Red Builders since they were sensible and their quote was all around organized and detailed. The Job included a lower ground expansion and house redesign. I don't have anything but beneficial comments about capability. Their work was done to the highest level. Their tiling, carpentry and painting were remarkable, and the project was finished on schedule and due to the plan. They were negotiable about the inside plan changes and permitted me to be engaged with the cycle even to the point of helping me source-specific installations I needed for the house, keeping in topic with the style we had gone for. They gave me useful recommendations on specific components I had disregarded, for example, up-cycling the current wood planks, extra water siphons required and incorporating the outer bi-folds to make the augmentation even from the outside instead of inside. On-demand Red Builders made cabinetry around our chimney to match our new kitchen and truly, the craftsmanship and detailing makes them appear identical. When the undertaking was done, it was hard to accept that it was the same house.
When embarking on discovering an organization to plan and build our office, I had clear models at the top of the priority list. The organization must be lively, clever, solid, overflowing with thoughts and value for money. Red Builders beat the competition by a reasonable mile. Indeed, even before winning the project, the attention they paid to us was unmatched. When we began, the norms didn't drop. They committed an over the top measure of time to my venture and went far above what was required even to where it was evident it wasn't to their greatest advantage to do so. They were very supportive all through the process, continually delivering on our details and deadlines and totally adaptable toour tasteful changing preferences. They're similar to an extended family on building site. Without any doubt, the best I've worked with.
I have been suggested Red Builders through a friend of mine who had their kitchen wonderfully extended so we chose to reach them about a potential loft conversion and we couldn't be more grateful. The plans were delivered very fast, precisely, and I truly felt they accepted our interests and thoughts, parts that were not achievable were given different other options, and they truly set us straight during this process. We are happy with the outcomes from the start to the end. Strongly recommended. It was a pleasurable experience, and I wouldn't hesitate to use again.
We are living abroad, and after a tenant had harmed our terraced house, we found that we need to set out on a top to toe restoration of our property. We got various quotes, and the Red Builders reaction was the most careful and thorough. Red Builders were incredibly useful in working through the selection and reacting quickly to each of our inquiries and concerns. Red Builders might not have been the cheapest reply we got, however, there was absolute clarity on what we were paying for and the nature of work we were getting. The project manager and his group at that point dealt with the venture, especially professionally - with regular and definite email and photograph refreshes, they exceeded all expectations in conveying a remarkable outcome for us. Our home presently looks spectacular - and each renting office that has seen it has remarked on the exceptionally high caliber of the work. In case we needed to do this once more, we wouldn't spare a moment to call Red Builders, and are very glad to prescribe them to anybody searching for top quality, productive, friendly or more all very professional and experienced building company.
Red Builders changed over a mid-Victorian patio loft. It was done due to the deadlines confirmed at the beginning and the budget approved, with a magnificent quality completion. The group of manufacturers, builders, electricians and plumbers set up by Red Builders were unpretentious and extremely enterprising. When there were inquiries en route, they were replied, and the Red Builders group were consistently accessible on the mobile if necessary. Red Builders were flexible and responsive. I was not anticipating works in the house, but once they were in progress, I was incredibly satisfied with how they went. I would suggest Red Builders without a second thought and would use them again for a similar activity without hesitation.
