Level thresholds can be very difficult to detail, with many standard details always showing a 150 mm step between the finished floor level and external ground level. However, level thresholds provide a future-proof solution to an aging population and ensure a building can be used and visited by everyone. They are also a very aesthetic solution to bridging the gap between indoors and outdoors.
Level thresholds are also a legal requirement for new build housing in the UK. This means that all external doors, front, rear and side, plus any sliding, bifold, French or terrace doors, must provide a level entrance and exit. Although it is not a building regulation requirement in renovation projects, some councils may require level thresholds as a planning condition within extensive renovation projects.
Below we look at key considerations when designing level thresholds to ensure water does not enter the building.
Bienville House by Nathan Fell Architecture, New Orleans, LA, United States
Accessible / Level Threshold
An accessible threshold is defined as a threshold this is level or, if raised, has a total height of not more than 15 mm, a minimum number of upstands and slopes and with any upstands higher than 5 mm chamfered.
Building Regulation Requirements
For single new build properties, Building Regulation Part M4(1) and M4(2) must be met. This requires all access to the dwelling to be step free, including the entrance, garden and any terraces. For larger developments or flats, the local council may require 10% of units to meet Building Regulations Part M4(3), meaning the unit is fully adaptable to a wheelchair user.
Whilst these Building Regulations do not need to be met in the case of an extension, some Local Authorities, Building Control and/or Approved Inspectors may require the need to meet Part M4(1) within a planning approval condition, requiring entrances and exits to the house to be accessible.
Ground Floor Thresholds
LHS – In-situ concrete threshold drain built under the sill and pavers, pavers to be removable or inspection hatch to be provided at either end of the drain for cleaning and maintenance.
RHS – Aluminum threshold drain installed between pavers and sill with removable grill for inspection, drain with low level water entry of water infiltration between drain and sill.
There are various ways of designing a level threshold based on aesthetic, cost, structure, site conditions and location. However, there are a number of key features that all level thresholds should take into account.
Door — When specifying a door to be used in a level threshold, most manufacturers will state if the system is compliant with Part M of the Building Regulations. This guarantees that the element you step over is no more than a maximum 15 mm in height with no upstands of more than 5mm. Most sliding door manufactures provide frames with a completely level base frame. However, it is important to check the base frame of elements such as front and rear doors, especially in timber, as these will need special aluminum thresholds to be fully accessible.
Threshold Drainage — This is a building regulations requirement when designing this type of threshold. A drain can be installed between the sill and external landscaping flush with the level floor or hidden under the finishes. Many door manufacturers will even be able to provide a threshold drain for the door system chosen. This will help drain away any water near the drain as well as water which hits the door or glass and drains through the frame.
Threshold drain designed to clip into the aluminum sliding door system to drain both surface rain and rain hitting the glass and filtering through the window frame.
Waterproofing — Damp proof membranes should be draped up the door or window frame system at the point of the threshold. Water should be moved away from the threshold, by sloping eternal finishes away from the drain. To either side of the threshold, the damp proof course should be minimum of 150mm above ground level.
Key Points To Remember
The threshold — including the door frame — should not be more than 15 mm in height overall. Of these 15 mm, there should be a minimum number of upstands and slopes, with any upstands higher than 5 mm chamfered.
If the threshold is exposed to wind driven rain the landing can be up to 10 mm below the level of the sill if the sill is rounded or chamfered.
The external landing should have a fall ratio of between 1:40 and 1:60.
Ensure all water falls away from the doorway in a single direction.
Build a drainage channel between the landing and the threshold.
Ensure the channel discharges to a drainage system or land drainage such as a soakaway.
Timber Frame Key Considerations
LHS – Timber frame construction either side of threshold showing concrete slab construction and raised foundation blocks 150 mm above finished floor level, with threshold drain.
RHS – Level threshold with drain
Usually when designing for a timber frame structure, the timber frame should begin 150 mm above the ground level. This concept should be maintained when the ground level externally is level with the internal finish floor level. All the same considerations as above should be taken to account as well as the foundation or timber structure being raised 150 mm above the external ground level, usually 150 mm higher than the internal finished floor level.
Raised Terrace
Another way of preventing water ingress at this critical junction is to use a raised terrace such as paving slabs on pedestals. Whilst this is the best option if you have a raised terrace area, it is also used when the garden level is lower that your internal ground floor level, such as with a beam and block construction. Further details can be found in the following section.
Level Balcony and Terrace Thresholds
When designing a level threshold onto a raised terrace or balcony, even more care needs to be taken to assure that water does not enter the building fabric.
When creating a level threshold over a heated space, care needs to be taken when setting the internal finish floor level and ceiling level to allow for the new insulation. Many people opt for vacuum insulation to this area to allow for a reduced terrace build-up.
Adjustable pedestals can be used to bridge the gap between the level pavers or timber deck with the sloped flat roof. The gaps between the deck material is also key in allowing the water to drain through to the roof and the roof outlet.
Key Points To Remember
The threshold including door frame should not be more than 15mm in height overall. Of these 15mm, there should be a minimum number of upstands and slopes, with any upstands higher than 5mm chamfered.
The gap between door sill and paving or timber to be a minimum of 10mm.
The gap between paving or timber to be a minimum of 6mm.
Flat roof to have 1:40 falls for a 1:80 minimum built slope.
Ensure all water falls away from the doorway in a single direction.
Build a drainage outlet on the opposite side of the flat roof to the threshold.
Ensure the flat roof has an overflow.
Ensure all waterproofing has a minimum of 75mm upstand under the threshold.
Provide a minimum 150mm waterproofing upstand to sides such as brickwork.

Are you interested in improving your architectural drawing technique? Follow along as the Founder of 30X40 Design Workshop and One Drawing juror Eric Reinholdt designs and draws an architectural lighting plan showing the necessary fixture types, switching, receptacle locations and all electrical devices and equipment. Designing such details in coordination with the other essential building systems — architectural, structural, mechanical and plumbing — affords the architect more control in the final outcome by anticipating how these systems will work in conjunction with invisible elements such as beams, ductwork, vent stacks.
Drawing and overlaying each helps to identify conflicts on paper where it’s much more efficient and cost-effective to make changes. In this video, you’ll see how the abstract concepts of ambient, task and accent lighting are accounted for and applied in a real-world design of a remote, off-the-grid residential project in Maine, USA.

If you were to name the hardest occupations in the world, being an architect would undoubtedly be up there — but being a mother might the most challenging job of all! It is understandable, then, that the prospect of being both an architect and a mom simultaneously might feel like an insurmountable task. Juggling parental duties with professional responsibilities is undeniably daunting for many, no matter how great your support network may be.
Thankfully, it’s possible not only to cope with this challenge, but to thrive — and Gloria Kloter is here to tell us how. Now available for pre-order, her book The Architecture of Motherhood: Your Blueprint to Glow as a Business Woman and Mom details a multitude of ways in which women can be both a top professional and a stellar mother, without the need for compromise.
Gloria Kloter is the founder and CEO of Glow Architects, a successful architecture and interior design firm based in Florida. She has been working in the architecture field since 2004 and is an inspirational keynote speaker advocating for subjects like leadership, women in architecture, foreign architects, and motherhood. She’s a multi-award-winning architect who has been featured in major publications, news, and architecture magazines in the United States, the Dominican Republic, and worldwide.
In her preface, Kloter highlights a key disparity in numbers: “In its 2020 annual report, the National Architectural Accrediting Board (NAAB) revealed that 50% of the 26,977 students enrolled in NAAB-accredited architecture programs – B. Arch, M. Arch, and D. Arch– were female. This is a number that has been improving since the 1970s, yet the percentage of women who obtained their architect license, achieve upper management positions, become partners and own architectural firms have not increased at the same rate as men have. To date, data from the National Council of Architectural Registration Boards (NCARB) 2021 NCARB by the Numbers report shows that only 24% of the 121,997 registered architects in the United States are female.”
Data like this risks planting seeds of doubt in the minds of women starting out in the profession, and Kloter was no different in this respect. “Based on these facts, I was worried that if I started to grow my family, then it would be the death of my career,” she writes. “On top of it – and like most women experience – I was continuously pressured with unsolicited advice and opinions on how I needed to start having kids early and how as a woman, I should have a family or a career, not both. Many conversations around me implied an unspoken shame and a sense of guilt in wanting to still have a professional career after having kids.”
“Why would you want to keep working?! Aren’t you planning to have kids?!” – Someone once asked me, horrified after hearing about my professional aspirations when I got married. I was also once told that if I would try to take these two roles at the same time, I was going to fail at one of the two, or at both. It was important to choose between one role and the other, and focus on being successful at that single one. Period. Yet, there was a part of me that couldn’t accept this theory entirely. There had to be a better way.”
Kloter’s book contains a wealth of practical advice to balance home and work life, as well as powerful motivational tools to instill belief in women, encouraging them to embrace their capabilities to be renowned architects and incredible mothers. The following quotes provide a teaser for the words of wisdom that you can find throughout the book:
1. “Architecture is an interdisciplinary, collaborative, and creative world. The same can be said for motherhood.”
2. “Your support system can make or break you. It’s an essential piece of the puzzle to find the balance between motherhood and business.”
3. “When thinking of tools to ease your professional life and motherhood, the first thing that comes to my mind is delegate, delegate, delegate.”
4. “A thriving environment is where your weaknesses are balanced out by others’ strengths. This can be said in business and motherhood as well.”
5. “Don’t let other people’s limitations limit you.”

Thinking of using stone in your project? Our latest Dezeen guide includes 15 popular types of natural rock used in architecture, interiors and design with links to hundreds of examples to inspire your own work.
Alabaster
Alabaster is a soft, fine-grained stone that has been used for centuries to carve elaborate forms and ornaments. However, its solubility in water means that it is best suited for indoor use.
In its pure form, alabaster is white and translucent, which makes it ideally suited to lighting design.
Studio Tack used tubular light shades made from alabaster to softly illuminate a cosy Japanese restaurant in New York (above), while lighting studio Allied Maker used the stone to create ornate totemic floor lamps.
Amarist Studio showcased the sculptural possibilities of the stone in its Aqua Fossil collection, which includes a coffee table with swooping, curved legs.

Basalt
Basalt is a dark-coloured igneous rock that is formed when lava cools rapidly. It is most frequently used as an aggregate for concrete as it is low-cost and high-strength, but it is also a popular cladding and flooring material, especially when polished.
Examples of this include the facade of a small gallery in Amsterdam by Barend Koolhaas and a Hawaiian holiday home by Walker Warner Architects in which slender basalt cladding tiles are contrasted with cedar detailing (above).
Icelandic studio Innriinnri used two sculpted slabs of basalt stone to create a sculptural table that doubles as a stool or a piece of art, while South Korean artist Byung Hoon Choi polished the stone to create oversized outdoor furniture.

Flint
Flint is a highly durable stone found in abundance as irregular-shaped nodules in sedimentary rocks such as chalk. It has been used as a construction material since the Roman era, though it is not often seen in contemporary architecture.
Flint varies in colour, but it is commonly glassy black with a white crust. In architecture, it is usually knapped – split to expose its glossy inner face – before being laid in mortar.
Skene Catling de la Peña used a combination of knapped and unknapped flint to cover a wedge-shaped house in Buckinghamshire (above), which creates a subtle colour gradient across its facade.
See projects featuring flint ›
Gneiss
Gneiss, a robust metamorphic stone composed of alternating layers of different coloured minerals, is popular to use for flooring and worktops. Hues can range from pinks and golds to greens and dark greys.
Peter Pichler sourced grey gneiss with black-and-white bands from Passeier Valley in South Tyrol to create a large counter in the bar of an Italian Alpine hotel (above).
It can also be used as a cladding material, such as in Bernardo Bader Architekten’s ski resort office in Austria and a radio broadcasting station in Nepal by Archium.
Granite
Granite is one of the most widely used stones in architecture and design. It forms from the slow crystallisation of magma beneath the Earth’s crust. It is used for everything from load-bearing structures to cladding, worktops and furniture.
Its popularity is down to its high compressive strength, durability and low porosity. Granite is also found in an array of colours, making it suitable for a range of spaces and styles.
Heatherwick Studio recently used green granite to make a trio of its sculptural Spun chairs (above), while Snøhetta has used a grey variety to cover almost every surface of an Aesop store to emulate a rocky coastline.
Architecture studio NOARQ tested the material’s strength by elevating a cabin on thick blocks of granite over the entrance to a stone villa in Portugal.
See projects featuring granite ›
Laterite
Rusty-red laterite stone is formed from the leaching of rocks and soil during alternating periods of high temperature and heavy rainfall in tropical areas. This process leaves behind a high concentration of insoluble iron oxides, which gives the rock its colour.
Laterite is typically used in construction in Africa and Asia in the form of bricks, which have excellent thermal mass and a low embodied energy. These bricks are made by cutting the rock out from below the water table when it is moist and leaving it to harden in the air.
Architect Francis Kéré used locally sourced laterite to build the walls of a school in Burkina Faso and Studio Lotus has used it to create the pedestal of a government building in India (above).
Limestone
There are many different types of limestone, a sedimentary rock composed mainly of calcium carbonate. It is considered a good all-round building material as it is easy to cut and carve and usually has a uniform texture and colour.
Popular limestone varieties include travertine (see below) and Portland stone, which is used on notable buildings in London such as St Paul’s Cathedral and Buckingham Palace.
David Chipperfield Architects recently used limestone to clad the Kunsthaus Zurich museum extension in Switzerland and John Pawson used it to line the surfaces of a minimalist flagship store in Japan for fashion label Jil Sander.
Design projects that utilise limestone include a blocky furniture collection called Dig Where You Stand by students from the Estonian Academy of Arts (above).
See projects featuring limestone ›
Marble
Marble is a metamorphic rock with veins of calcite crystal. It forms from limestone that has been exposed to heat and pressure and is found in many colours. Marble is strong but easily carved and polishes well, making it suitable for numerous applications.
It is most popularly used in kitchen and bathroom designs, but it is often used as cladding too, such as in Alexander Owen Architecture’s garden room in London (above).
Onyx is a translucent gemstone composed of parallel bands of quartz, found in almost every colour. It has a long history of use in sculpture and jewellery but is less commonly found in architecture and design. However, onyx is sometimes used as a facing or lighting.
Projects that use onyx include a mausoleum in Minneapolis by HGA and an office by Anne Claus Interiors where it has been used to clad a multi-coloured bar (above).
Porphyry is a strong and hard-wearing igneous stone that comes in reddish-brown to purple hues. It is composed of large-grained crystals embedded in a fine-grained groundmass.
It has been used in architecture and design since antiquity, though it is rarely seen in contemporary architecture and design. Today it is mostly used as aggregate in the construction of roads in places where cars require studded winter tires.
Pedevilla Architects used a block of porphyry as a kitchen island for a cookery school in South Tyrol, while architect Claudio Silvestrin used it to line the walls of a Milanese fashion boutique.
Quartzite
Formed from sandstone exposed to high heat and pressure, quartzite is a very hard and durable metamorphic rock. It is usually found in white and grey shades.
Quartzite is a popular material for kitchen countertops as it is resistant to staining, but is most commonly used as a decorative cladding or flooring.
Examples of this include a dwelling in Utah by Klima Architecture, Peter Zumthor’s Therme Vals spa (above) and a monolithic Parisian library by Agence Pascale Guédot.
See projects featuring quartzite ›
Sandstone
Sandstone is composed of fine silicate grains that have eroded from other rocks, giving it either a warm red, yellow or orange colouration.
Used for construction since prehistoric times, sandstone continues to be a popular choice in architecture and design as it is abundant, durable and easy to handle.
Recent architectural projects that use the material include a cathedral extension by Feilden Fowles, a museum by Álvaro Siza, and an oval-shaped all-girls school in India (above) that is designed to blend into its desert surroundings.
See projects featuring sandstone ›
Shale
This grey fine-grained stone is one of the most common sedimentary rocks on earth. It is formed from the compaction of silt and mud into thin, fissile layers. In architecture and design, shale is usually crushed and processed into bricks, tiles and pottery, or heated with limestone to make cement.
Aketuri Architektai used shale tiles to clad a pointy woodland house in Lithuania (above), while Spaceworkers wrapped the stone around the basement of a Portuguese house to provide it with a raw, rugged aesthetic.
See projects featuring shale ›
Slate
Slate is a dark fine-grained stone that is formed when a sedimentary rock, such as shale, is subjected to high pressure. It is a foliated rock, meaning it is made up of thin sedimentary layers, which allows it to be split – or riven – into thin slabs.
Slate is durable and weather- and frost-resistant, making it a popular material choice for cladding, roofing and paving.
In interior projects, the material is often also used as floor tiles, hearths and kitchen worktops. Natalie Weinmann sanded and polished the stone to create a blocky furniture collection.
TRIAS used it to clad a small writer’s retreat in a Welsh valley while Austin Maynard Architects diamond, scalloped and brick-shaped slate shingles to cover a Melbourne house (above).
See projects featuring slate ›
Travertine
One of the most commonly used forms of limestone is travertine, which has been sourced from mineral springs for use as a building material for centuries. The largest building in the world made from this stone is the Colosseum in Rome.
Today, travertine is mostly processed into tiles for internal and external surface coverings, but it is also a popular material for bathroom fit-outs. As it is found with troughs on its surface, processing travertine usually involves polishing its surface.
Projects that use travertine include an extension to a German museum by Bez + Kock Architekten (above), an apartment renovation in Lithuania by 2XJ, and a furniture collection by David/Nicolas.
See projects featuring travertine ›
Recent popular stone projects on Dezeen include an inconspicuous house on the island of Serifos, a monolithic spa by Smartvoll, a collection of luxury lodges on England’s Jurassic Coast and a coffee table by Studio Twenty Seven.
