If it is 2.2m or higher, then it is enough for conversion. Keep in mind that Victorian houses have less head height which is not sufficient to convert a loft.

Type of Roof

Do You Need Planning Permission?

Well, you can change agricultural buildings to residential ones in England. However, you need to notify the local council about it. It is better to check with the local council about approval of noise impact, contamination, vehicular access, and flood risk. Furthermore, the council will check if there is the harm in changing from agricultural to residential use. The process is not simple but more straightforward than making a full planning application.


Usually, the barns are used for storage and other agricultural needs and not meant for living. So, it is essential to hire a surveyor to checks its stability. Things that you need to look are the foundations, roof structure, and load-bearing walls. If you need to add the second storey, then the barn will need underpinning.

Insulating Barn Conversion

A barn is meant to store agricultural things and not intended for living. Hence, they have not insulated property. One of the first things that you need is to insulate the barn according to the modern standards. Some people want to preserve the cladding, so they need to insulate the walls internally. There are various ways to do this, such as fitting breathable insulation such as sheep wool.

Furthermore, if you want to keep the vaulted ceilings too, then you need to fit the insulation between rafters. You also need to dig the floor to install insulation boards.

Utilities and Services

It is usual for the barns not to have water, gas, drainage, and electricity. Hence, you will need these connections for the conversion, just like other house extensions. Get quotes from the utility suppliers to get an estimate of the cost. A rough estimate is that it can add up £1000 to your budget.

Barn Conversion Heating

Most of the experts recommend underfloor heating for barns. Because it is a great way to keep the living space warm, it also means that you do not need to attach radiators to the walls. It can get cold in the UK, so it is better to have an efficient heating system for the conversion.

Cost of Attic Conversion

Just like with any other house extension, the cost of attic conversion depends on the size. The average cost is anywhere between £15,000 to £20,000.

In this way, the renter will have its personal space. However, there are some formalities to rent out a room in your house. So, it is better to check with the local council before doing so.

Attic Conversion


Walls provide support for the attic, and it usually has knee walls. As you have a small space, so you need to maximize it. You can consider built-in seating to keep these short walls.


Well, the ceiling is the main focal point for any person entering the room. You can consider the sloped ceiling, which looks unique and exciting. You can get most of it by having a good design for the room.

Bedroom Conversion

One of the best ways to make use of this extra space is a bedroom conversion. The shape of an attic makes it a right candidate for children’s room. You can decorate it in a way that enhances the nature of the attic bedroom so that children feel comfortable walking around the sloped ceiling. If your kid is a teen, then it is a good idea to give them little space on its floor.

Basement Conversion London Guide for Homeowners

A basement conversion can help provide valuable extra living space, and it does not require any change to the exterior of your home. Everybody wants more space in the home, and one of the ways is by house extension or converting the basement.

Loft Conversion provides additional living space on the top of the house. You can use it to create additional bedrooms. On the other hand, a basement is close to the main living space and access.

Options for Basement Conversion London

If you want to create living space underneath the home, then there are the following routes:

  • You can create a basement
  • Or you can renovate an existing cellar or basement
  • If your house does not have a basement, then you can build a new one underneath the home or can extend out into the garden.

In this article, we are going to discuss 2nd and 3rd routes.

How Can You Use Basement For?

There is no doubt that the basement is a great space for your family; you can convert it into a home entertainment room or playroom. You can also use it as a utility room, storage and boiler furthermore, as the basement has its external entrance which makes it a self-contained unit, which makes it an ideal space for annexes or home office. If you want to make It an independent separate dwelling, then you need to express consent.

Does Basement Conversion London Worth It?

Whether a basement or cellar conversion worth your money depends on the cost and value of the property, additional living space under the house does make financial sense in high-value areas. If you are living outside London, then you need to take this decision after careful analysis. If you want to get an idea about the worth of space per square meter, then you can ask them from a local estate agent.

However, you should keep in mind that a basement with direct access worth more than any other dark cellar space. You also need to keep in mind that an area has a maximum value which you cannot exceed no matter what improvements you make. It also means that converting your basement is not going to increase the value of the property.

Sometimes, it is challenging to decide whether to convert a loft or a cellar. Because both of them costs about the same, but building a basement from scratch is a daunting and expensive task. However, creating a cellar will provide you with useable floor space compared to loft conversion.

Planning Permission for Basement Conversion London

If you already have a cellar beneath your home, then you do not require planning permission for conversion. Because it comes under permitted development unless you are in a conservation area, if you are going to reduce the floor level of a basement to improve the ceiling height, then it will be treated as an extension which needs planning permission. However, some of the alterations and extensions also do not require a planning application; for more information, you can visit the planning portal, or you can visit the office of the local council.

The planning policy for the basement varies from one location to another. However, getting approval from the local council is not that difficult. If the work is not going to alter the appearance of the house, then the council does not have reasonable grounds for refusal. We have seen many people made iceberg basements which indicates that the policy for basements is still under review.

Basements and Building Regulations

If you are going to create a new basement, then you need building regulations approval. It does not depend on whether you are going to use existing cellar or creating a new one. These regulations are to make sure that the buildings are safe, energy-efficient, and hygienic. Renovating or repairing a current basement does not require building regulations approval.

You can download the documents from the government website. That is why; we recommend our clients to apply for planning permission rather than waiting for notice.

Party Wall Act

If the work is going to affect any party wall, for example, if the excavation is to be carried out near a party wall, or you are going to extend the wall. In such a case, it is essential to inform all the owners of adjoining properties.

How Long Basement Conversion LondonTakes?

A basement conversion usually takes a few weeks to complete. If you are going to convert a simple bedroom, then it will take just two or three weeks. But if you are going to convert the basement of the entire house, then it can take several months. Furthermore, if you can access directly, then you can live in your home during the work. But if the contractor has to remove the ground floor and rebuilt it, then you have to move out.

Natural light is essential for a kitchen, so we will recommend you to use floor-to-ceiling glass. Some of the people choose French patio doors, but we will advise you to fit bi-folding doors. This type of doors provides a great view of the garden. You also need to consider how you are going to separate these two areas. The open plan works best for most of the people but keeps in mind that these two spaces should have their own identity.

In this article, we are going to talk about some tips and the paperwork you need for an extension. It is a tedious process, but, on the other hand, it has some benefits. So, we will discuss all building a home extension. Moreover, we will discuss the different steps involved in the planning and building process.

Home Extensions – Checklist

Following is the checklist of the steps you need to take before adding an extension:

Planning Permission

People who are new to adding home extensions do not know about planning permission. It is a legal barrier that you need to cross before starting work. You need to get planning permission from the local council. It is a lengthy process that can take a couple of weeks, so it is better to apply in advance. Another thing is to talk with neighbours to resolve any issues to save quality time. You need their signatures on the party wall agreement. These kinds of things can cause significant delays in the projects.

Furthermore, you need to find a good builder and a design. No matter, you are having a kitchen extension or conservatory extension, you need an architectural services provider and a builder, you can trust. Tell them all of your needs so they can provide you with a good design of the extension. You should finalize the design before applying for planning permission. If you want any change after the approval, then you may need to submit it again to the local council.

Some of the extensions do not require planning permission. However, we recommend our clients to apply to avoid any legal complications during the work.


It is essential to read and understand the contract before signing it. If you are unable to understand, you can get legal advice or can ask the contractor. You also need to make sure which type of contract you are signing.

If it is a fixed-time contract, then the start and finish date should be mentioned. Another thing to know is your rights if something goes wrong. Also, make sure that the builder has insurance coverage for theft and damage during construction.


You should keep all the documents such as planning permission, party wall etc. in a file. Also, keep a record of all the receipts, contracts, and plans related to the project. Track the progress of the project and stay in contact with the contact managers, builders, and surveyors throughout the construction process. It is the only way to make sure that the project will complete in a specified period.

Sometimes, the owner lives far from the construction site, and a daily visit is not possible. In such condition, keep in contact with the office of the builders through the phone. Ask the phone number of the builders, surveyors and project managers to get updates about the project.

However, we will recommend you to visit the site twice in a week and report any defect to the project manager. They will not charge you for any fixes until the project is completed.

Home Extensions ideas

We need a home extension when we need more living space for our family. There are various types of home extensions; each one has some advantages as well as disadvantages. Following are some house extensions ideas for you:

Single-Storey Home Extensions

If you are looking for the most cost-effective home extension, then the single-storey extension is for you. In this extension, we build a house in the rear or side of the house.

Multi-Storey Extension

The multi-storey extension can help you get extra living space. However, it costs more than a single-storey extension. Furthermore, obtaining approval for this type of extension is difficult. You can choose to maximize the space of the existing room or can add new places to different floors.

Adding A Storey

You can also choose to add a storey above the home. Getting approval for such an extension is secure and can double the space in your home. It can also increase the value of your property. However, it is an expensive option.

Adding Space Underneath

As the title implies, you add more space underneath the house. These types of extensions require structural changes so that they can be extremely costly.

Last Words!

There are plenty of ways to get some extra living space in your home. Which extension works best for you depends on your requirements and most importantly, your budget.

How Much Does A House Extension Cost in 2020?

Getting an extension can be complicated; there are lots of costs and rules and regulations. You need to understand that there are lots of factors that affect the house extension cost. We have seen many people get beyond their budget while getting an extension. Hence, it is essential to get a clear idea of the cost before you start working. There is a house extension cost calculator available on the internet, but these are just average values, and they rarely update the database.

House Extension Cost

As with building a new home, the cost of an extension varies depending on your needs. A simple design with necessary materials is cheaper. However, the cost of the kitchen extension, single-storey extension, and two-storey extension can differ from each other even if you are using the same design and materials.

Another factor that can affect your budget is the location of your home. If you are living in central London or anywhere near then a home extension will cost more. So, keep this important thing in mind while making a budget. However, it does not mean that there are no rules for estimating the cost. Following are some average numbers for each kind of extension. These are just average, but you can get a general idea about how much does an extension cost.

Single-Storey Extension

It depends on the size of the single-storey extension. If we talked about the average in 2019, the cost could be anywhere between £1,350 and £2,000 per square meter. However, the average cost in the South East and London was between £1,800 and £2,3000 plus per square meter. These prices are for a useful quality extension, which means there is a room for saving some money.

If you just need an essential extension, then the cost will be a lot less. For example, you are looking for a 5m x 5m extension, then you can expect to pay around £31,500, but in London, it can go up to £49,000 plus. Keep in mind that we have not yet added the fees for architectural services providers, building regulations, planning permission, project manager etc.

Two-Storey Extension

So, what about a two-storey extension in the UK? If both of the stories are of the same size, then you need 50% extra to add another storey. For example, if single-storey house extension costs you £39,000 then adding storey will cost you £58,500. You also need to add VAT and other professional fees and the total cost of a two-storey extension will be around £76,050.

Bathroom or Kitchen Extension

When we talk about a kitchen extension and bathroom, things are a bit more complicated. There are lots of things such as planning permission and plumbing that can affect the cost.

If you want a bathroom, then add £5,000, but this can cost higher depending on the finishes and what you want from the bathroom (shower, bath, toilet etc.). However, the cost of a kitchen extension can go up to £10,000. Keep in mind that it is the cost of a basic kitchen- a fancier one is pricey.

Bungalow Extension

I hope you get an idea about the house extension cost, but what if you own a bungalow? What you need to expect to pay for getting an extension. Do not worry! The cost of the bungalow extension is the same as a single-storey extension.

Up in the Attic

There was a law for maximum ceiling height. However, it is not applicable anymore. But you still need to maintain a practical height for the ceiling. You should keep this mind, especially for a cellar and attic conversion. Most of the people choose a height of 2.1m to 2.4m.


We have already explained that finishing can add to the cost of a kitchen and bathroom extension. If you are good with simple walls, floors and lighting, then you can save some money on finishing. But if you want premium stuff like flooring, tiling, joinery etc. then the cost of an extension will increase. So, keep this in your list while estimating the cost.

In short, you need to keep in mind the things that you want in an extension.


Another important thing that people miss while calculating house extension cost is windows. I know they can be expensive, but these are an essential part of some extensions. Bigger the window, more prominent will be the cost. Furthermore, the glazing and insulation also add to the cost of windows.

Additional Costs

While calculating the prices, do not forget about other costs. You can get the help of a builder to help you factor any extra cost. These factors are as follows:

  • Type of the soil which requires unique material and techniques
  • Change in the existing structure
  • Access to the site.
  • Moving gas meters, pipework, and drainage will cost more and require extra planning.
