Bespoke Loft Conversions in Architect London
Our loft conversion team throughout London provides high-quality bespoke loft conversions throughout London and the home counties.
We have completed a number of bespoke loft conversions in architect London that are completely suited to the client's unique needs and tastes. A basic flat roof dormer is the most common style of loft conversion.
This is a structural addition that extends vertically from the original roof's slope, forming a box shape. This loft addition requires no major adjustments and allows for the installation of standard windows. A flat roof loft conversion can add a lot of space for people who don't have the biggest of houses.
Types of Lofts
We provide a variety of loft conversion types such as a dormer, mansard, hip to gable, L-shaped, and Velux loft conversions.
Our construction crew will remodel your home, providing you with extra living space and improving the value of your property.
We want to make the loft conversion process as simple as possible for you from start to end, keeping you informed and involved at all times. Architectural drawings and structural calculations are followed by a preliminary survey and design in our procedure.
After that, the designs will be utilised to create a quote. When you accept our quotation, our architects will apply for planning approval, start construction, and then finish your new loft conversion.
Our staff is always available to go through any area of the project in further depth. A loft conversion is an excellent option to expand your living space, whether your family is growing, you're renting out a room, or you simply want a new study or office.
This is a less expensive alternative to moving, and it will increase the value of your property if you decide to sell it later. Regardless of the scope of the project, we will design a loft that represents your style and meets the needs of your lifestyle.
Dormer Loft Conversions
One of the most cost-effective ways to increase your living space without sacrificing yard space is to convert your loft.
When there isn't enough space in the yard and the only option is to rise higher, dormer loft conversions are particularly prevalent in urban areas in the United Kingdom. In recent years, improving your home rather than relocating has become increasingly trendy.
Among the most common types of loft conversions in the UK are dormer loft conversions, which are roof extensions that add height and square footage to a home.
Dormers are usually installed on semi-detached or terraced houses - dormers are roof extensions that extend vertically to add floor space. Dormer lofts are box-shaped structures with 90-degree floor walls and a pitched roof.
In contrast to a Velux loft conversion, a dormer conversion necessitates structural changes to your roof. Since work is done from scaffolding outside your home, this form of loft conversion causes the least amount of interruption.
There are several different varieties of dormer loft conversions, and which one is ideal for your house will be determined by the type of property (terraced, detached, or semi-detached) as well as the present roof size and form.
Mansard Loft Conversions
Mansard loft conversions, as opposed to dormer loft conversions, involve more substantial changes to the building. The roof has two slopes: the upper slope is approximately level, while the lower slope is nearly vertical at 72°.
Mansard loft conversions are often constructed by elevating the gable or party wall on both sides of the home. This will produce a profile for your mansard, allowing you to build a timber frame.
Francois Mansard, a famous French architect who created residences in the 17th century, discovered the Mansard loft conversion. Mansard built residences with lofty, expanded roof surfaces.
Our team understands that Mansard loft conversions are more challenging than other types of loft conversions. It does, however, provide a significant amount of living space to residences. The additional area normally extends over the place of the roof with this form of loft conversion.
With a mansard loft conversion, you'll have enough room to add a bathroom, bedroom, entertainment area, or home office. This will significantly raise the value of your home.
This type of loft conversion works well in terraced, detached, and semi-detached houses.
Modern construction methods have made adding an extra level to a home with a mansard loft conversion, named after the renowned 17th-century architect François Mansart, more popular than ever.
This type of property improvement adds space to the roof of the house, but it is time-consuming. The conversions are typically large enough to permit numerous room additions, depending on the design.
It can, for example, house two more bedrooms and a bathroom.
The finishing may be done in a variety of ways to reflect the design of the property. Since most mansard conversions include structural changes to the roof's design, they need planning permission.
Mansard loft conversions are offered in several styles, including an L-shaped conversion - this type of conversion can create more space and have a greater impact on your property's value; this is the best conversion to create an open-plan bedroom with an ensuite bathroom. Two-tiered mansard roof - a double mansard loft conversion is offered in addition to the standard mansard conversion.
The home is distinct in that it has a Mansard attached to the front. This type of loft conversion is prohibited in some areas.
Mansard conversions are prevalent in densely populated areas when side and back yard space is restricted, or where homeowners want to save garden space by not constructing a ground-floor expansion. They are appropriate for a Victorian townhouse as well as a modern semi.
Hip To Gable Loft Conversions
A hip to gable conversion is suitable for homes with hipped roofs, which are inclined on one side of the house.
This kind of roof is commonly found on semi-detached and end-of-terraced properties in London and the home counties.
A hip to gable loft conversion will raise your head height to meet building requirements, allowing you to make greater use of your loft's interior floor space.
Hip to gable loft conversion is an excellent solution to solve storage and space problems without the inconvenience and expense of moving. Hip to gable loft conversions maximise floor area and height, and they can contribute significantly to the value of your home.
This is one of the most popular types of loft conversions, as it maximizes floor area and head height.
Check with your local estate agent to see how much a loft conversion will increase the value of your property, regardless of where you live.
The biggest advantage of a hip to gable loft conversion is the added space. Straightening up the sloped ceiling provides additional headroom, allowing for larger bedrooms and baths within your floor design. In general, the choices for converting a bungalow's loft are the same as those for a two-story home: adding a loft room, a dormer loft conversion, a hip to gable loft conversion, or a mansard roof conversion.
L-shaped Loft Conversions
One of the greatest loft conversion alternatives for increasing interior space and boosting headroom is an L-shaped loft conversion.
This type of loft conversion provides a number of layout options, including more than one room. An L-shaped dormer window is used in the L-shaped loft conversion. The two dormers in the L-shaped loft conversions intertwine into a corner.
The bigger end of the dormer is usually attached to the roof, while the smaller end is placed into the roof of an existing back expansion. The L-shaped loft conversion can give a headspace similar to the first-floor design.
An L-shaped loft conversion on a Victorian or Edwardian terraced property can result in a second room. Since this form of loft conversion requires a back addition, L-shaped conversions are only suitable for specific types of London houses.
Victorian and Edwardian terraces and end-of-terrace residences are a wonderful alternative for such a loft conversion, as most of these houses include a rear extension that forms the desired L-shaped roof.
Velux Loft Conversions
We provide Velux loft conversions, which are among the most popular and straightforward of all loft conversions. It is the cheapest way to enhance interior home space in the loft, and it does not even require planning approval.
In comparison to other loft conversion styles such as a dormer, mansard, and hip to gable, the Velux loft conversion takes very little construction and also causes a very little interruption.
Roof light loft conversion or skylight are other names for a Velux loft conversion. Velux loft conversions are without a doubt one of the most simple and cost-effective ways to increase headroom and maximise available space.
It also aids in gaining more natural light with good ventilation. In comparison to other types of loft conversions, such as hip to gable, mansard, and dormer, Velux loft conversions are less disruptive and need substantially less building work.
Our skilled loft conversion London staff guarantees that no harm is done, with maximum outcomes and no fuss by following all necessary procedures. Velux windows on the roof are required for that fantastic livable area.
We install this type of window as a loft conversion firm because it does not pitch out from the roof as dormers do, but instead stays in line with the current angle of the roof to enable natural light to stream in without affecting the roof structure.

CAN I CONVERT My LOFT OR ATTIC SPACE?
Loft conversions are frequently possible without the need for complete planning authorization. You could just require a Certificate of Lawfulness from the council.
If you wish to carry out your loft conversion under allowed development, consider the following rules. Please keep in mind that if you reside in a conservation area, a block of flats, or on designated land, you may need full planning permission notwithstanding the preceding advice.
In order to be considered approved development, your loft conversion must meet the following conditions, according to the Planning Portals Guide to Authorized Development: Any additional roof space shall be no more than 40 cubic metres for terraced buildings and 50 cubic metres for detached and semi-detached residences.
If your house confronts a highway, your loft expansion cannot extend beyond the plane of the present roof slope. You must employ materials that are the same as those used in your current home.
The extension cannot be taller than the current roof's highest point. Under permitted construction, a balcony cannot be installed. To safeguard your neighbours' privacy, any side-facing windows must be made of opaque glass.
They cannot be opened until they are higher above the level of the eye (specifically 1.7m above the floor height).
Roof expansions are not permitted to overhang the existing roof. They must be placed back from the original eaves by at least 20cm. (Unless it's a hip to gable extension.)
Suppose you are investing in a loft conversion to make it a playroom, upon completion. In that case, there are a range of regulations to follow - but aside from that, it is safe and approved, so you don't need to worry about your child falling through the roof or injuring themselves.
The most common application for a loft conversion is a bedroom with an ensuite, which is a terrific way to increase space within your home while also increasing the value of your property by adding another bedroom. Although designs and styles are frequently the first thought for homeowners, other aspects of a loft conversion, such as bathroom plumbing, may go neglected.
If you're planning a loft conversion with an ensuite, this best chance of increasing the value of your property or a new home.
Alternatively, a legal loft conversion is doubtful if your roof is lower than 2.2m since the completed height within the loft would be less than 2m. To get the necessary height for a liveable loft space, the existing ceilings in your upper rooms can be removed and the new structural floor erected at a lower level than the original ceiling. While this lowers the original height of your upper rooms, it provides the necessary height for your new loft conversion.
If you're not sure whether or not this applies to you, feel free to connect and discuss it with us and we can advise you.
A permanent stairway to your new loft conversion is required regardless of how much space you have available - little or huge.
Numerous variables will be reviewed, as with prior suitability studies, to ensure the staircase is safe and appropriate for the purpose.
A permanent staircase to a loft conversion is necessary by current rules for the formation of a liveable area, thus it is an important part of the build regardless of the available space – whether tight or with plenty of room to spare. There will be various considerations, as with the other suitability assessments, to ensure the staircase is safe and appropriate for the purpose.
Consider where your stairs will begin on the floor below, as well as the space you will lose to accommodate it, as well as the headroom required in the loft where the opening will be formed. Similarly, the limited space will affect how steep and narrow the steps may be.
A team of builders and building codes regulate the crucial proportions of the new staircase, including the proper pitch, to avoid trip and fall dangers. Your new staircase must begin someplace that does not interfere with the current arrangement of the home, and it must have a minimum height of 2m headroom at all times until it finishes in the loft.
In some circumstances, the new staircase can mirror the previous stairs and continue upwards without requiring extensive remodelling of the level it begins on, but in other cases, this will place it in the eaves of the roof, requiring a dormer to generate the necessary headroom.
A continuous layer of insulation installed over the rafters will eliminate cold bridging. This loft insulation approach also eliminates cold bridging, although it may limit headroom.
This issue is normally avoidable in new construction, but it might be problematic when converting an old roof. The most practical approach for insulating a loft is to install the majority of the insulation between the rafters, with a little supplementary layer connected to the bottom of the rafters. This is when insulated plasterboard comes in handy.
Good architects and builders incorporate this necessity throughout each project, and if the submitted information doesn't fit the standards for any reason, the home extension cannot proceed.
Our builders always utilise the latest technologies when providing additional room to your home and increasing your home value. For more detail, get in contact with us.
Most loft conversions are constructed to provide extra space. However, the loft extension can't exceed the existing roof slope. loft conversion requirements and building regulations require the structural strength of the additional floor to be sufficient, that there must be a secure fire exit, safely engineered stairs to the new level, and acceptable sound insulation between the conversion and the rooms below.
What's the Cost of Loft Conversion?
A loft conversion typically costs between £20,000 and £60,000. Each loft conversion is unique, and the cost will be decided by a variety of criteria, including the design of your home, its location if you require full planning approval, and, of course, your budget.
These factors will determine the sort of loft conversion you choose in order to maximise space and usefulness for your home.
You will normally have to pay an application fee if you need to apply for planning permission for your loft conversion. The price of planning applications varies substantially.
Renovations and additions to a single dwelling house in England, Scotland, and Northern Ireland normally start at £202 to £206 and escalate from there. In Wales, a loft expansion planning application can cost about £230.
Certain applications, such as those for listed structures or those to be destroyed in a conservation area, have no application fee.
Do I need Planning Permission for Loft Conversion?
Under Permitted Development, homeowners can usually extend their loft without filing a planning application.
Our team of experts can guide you through the process and ensure that your loft conversion complies with Permitted Development standards.
If certain restrictions and requirements are fulfilled, a loft conversion for your home is deemed authorised for development and does not require permitted development rights.
A party wall agreement is a legal agreement provided by any neighbours who may be impacted by your loft agreement or other improvements. The Party Wall Act of 1996 governs this and gives building owners rights that go beyond common law.
Will a Loft Conversion Add Property Value?
Converting your loft is frequently the most cost-effective option to increase the value of your home.
According to recent research by Nationwide Building Society, a loft conversion in the UK may add up to 20% to the value of your house, and if you want to convert your loft in London, your property worth can increase by 25%.
Of course, many of the advantages of a loft conversion will be realised only if the construction project itself is successful. Certain frequent mistakes can occur throughout the design and planning phases of a loft conversion, and the majority of them can be avoided.
If you properly plan your loft conversion, you will not only receive wonderful results, but the process will be a lot less stressful for everyone involved.
Adding a Loft conversion to your property

Loft conversions, in particular, are in high demand; they may be turned into a living room, storage, or whatever you choose, therefore, architectural designs are needed in order to map out your space.
Loft conversion drawings are necessary since they reflect the intended design and build of the loft conversion. This will provide you with an idea of how your loft could develop in the future.
Architectural design and build plans are often necessary when dealing with loft conversions.
