EXPLORE THE OPTIONSOUR SERVICES / 06
Single-Storey Extensions A single-storey extension adds ground-floor space and is often the simplest option to extend living or kitchen areas. It generally involves extending foundations, building external walls, installing a roof that ties into existing eaves and making openings between the old and new spaces. Key considerations include matching floor levels, drainage alterations, thermal performance to meet building regs, and how the new roof meets existing gutters and flashings. A measured survey and clear brief make cost estimation more accurate. Double-Storey Extensions A double-storey extension increases floor area on two levels and usually affects the property’s load paths and foundations. Expect structural checks and possibly larger foundations or reinforced beams to support new upper floors. Planning permission is commonly needed for taller additions, and building regulations will cover fire separation, stairs, insulation and structural design. Careful detailing where the new and existing buildings meet is essential to avoid leakage or thermal bridging. Early structural input helps control cost and timescale. Rear Extensions Rear extensions extend the back of the house to enlarge kitchens, dining areas or family rooms. They vary from shallow single-storey builds to larger two-storey additions. Considerations include access for materials, impact on natural light to neighbouring properties, drainage runs and how the extension roof integrates with existing rooflines. Good detailing around window and door openings and proper damp-proofing prevent condensation and water entry. Check permitted development limits and building regulations before starting work. Side Extensions Side extensions increase width or add accommodation to the side of a property but can affect access, neighbouring boundaries and roof junctions. They often require careful planning of guttering, downpipes and how the new roof ties to the existing eaves. Where the extension sits close to a boundary, Party Wall procedures may apply. Structural support at the junctions and adequate insulation and fire-stopping are important compliance items to address in designs and on-site work. Wraparound Extensions Wraparound extensions combine rear and side work to create larger, flowing ground-floor spaces. They can give an open-plan living area but demand attention to drainage runs, roof junction complexity, and how sunlight reaches the remaining garden. These builds typically need coordinated sequencing so roof, brickwork and openings are weatherproof as quickly as possible. Early decisions on glazing, thresholds and internal layout help avoid costly rework during the construction phase.
Single-storey extensions add valuable space on one level, often extending living areas or kitchens. They generally involve less complex structural work, though considerations such as garden depth, neighbour proximity and access for materials remain important. These extensions must comply with building regulations to maintain weatherproofing and long-term durability.
ENQUIRE ABOUT THIS SERVICEDouble-storey extensions create significant additional floor space by adding a full second level. This requires detailed structural assessment to ensure foundations and load-bearing walls can support the extra weight. Accessibility for construction work may be limited on some sites, and design must harmonise with existing rooflines and property aesthetics.
ENQUIRE ABOUT THIS SERVICERear extensions extend your home into the garden, commonly enlarging kitchens or living rooms. Garden size and local boundary rules influence design options. While this approach usually impacts the street view less, practical factors such as soil condition, drainage and neighbour relations must be considered carefully to avoid complications.
ENQUIRE ABOUT THIS SERVICESide extensions widen your home’s footprint and sometimes alter its street appearance noticeably. Adequate space at the side is essential, along with evaluation of pedestrian or vehicle access. These builds might have planning restrictions, especially in terraced or semi-detached settings, requiring clear coordination with regulatory bodies.
ENQUIRE ABOUT THIS SERVICEWraparound extensions combine rear and side additions to maximise available external space. These are typically more complex projects needing thorough site analysis for access, structural integrity and compliance. Effective coordination between roofing, brickwork and carpentry is critical to achieve a unified design that suits your home’s style and layout.
ENQUIRE ABOUT THIS SERVICEOUR PROCESS / FOUR STAGES
A straightforward extension process starts with a conversation and a survey. Typical stages: initial briefing, site survey and measurements, design and structural checks, planning or permitted development checks, building regulations submissions, groundwork and foundations, construction (walls, roofing, windows), internal finishes and final checks. We explain which stages need specialist input, such as structural engineers or architects, and we’ll set out likely timings and costs so you can plan without surprises.
We begin by discussing your space requirements, property type and site conditions. Understanding boundaries, access routes and existing structures helps gauge the feasibility of different extension options and informs the scope for design and regulations.
Designs are created to meet your functional needs while respecting planning limitations and building regulations. This stage addresses structural requirements, aesthetics, energy efficiency and integration with your existing home layout.
Construction starts with groundwork and foundation work, followed by masonry, roofing and carpentry. We coordinate these trades carefully to maintain quality and control logistics on site, managing timings and material deliveries within access constraints.
Final steps include internal finishing, fitting of fixtures and ensuring compliance with building regulations. Thorough inspections confirm structural soundness and weatherproofing before the extended space is ready for use.

INSIGHT / House Extensions Explained
Informed decisions on house extensions come from understanding design options, structural demands and regulatory requirements. This editorial details the essentials to help you plan a successful extension.
Choosing an extension depends on your home’s layout, available space and your aims. Single-storey extensions are ideal for expanding ground-level living spaces with simpler construction and less impact. Double-storey extensions offer greater space but need careful structural evaluation and can alter your home’s external appearance more significantly. Rear extensions make good use of garden depth to enlarge internal areas with minimal street impact. Side extensions require enough space and access and must consider visual effects, especially in terraced or semi-detached homes. Wraparound options combine rear and side expansions to maximise space but involve more complex construction. Considering factors like neighbour proximity, boundary limits and daylight is critical to selecting the best solution. When planning a house extension in Cheshunt, one crucial consideration is how your property's existing layout and site conditions will influence the scope and design of the build. For example, single-storey extensions tend to be more straightforward and less disruptive, making them preferable for homeowners prioritising quicker completion and budget control. However, if additional bedrooms or major living space expansion is required, a double-storey extension may be worth exploring despite its higher complexity, potential need for underpinning existing foundations, and more noticeable impact on your home's external appearance. Rear extensions capitalise on garden depth but check if your garden size and boundary constraints allow for the desired footprint without encroaching on neighbours. Side extensions often necessitate wider access paths for materials and equipment, particularly on semi-detached or terraced houses, which can limit feasibility if access is restricted. A wraparound extension combines side and rear builds but can increase structural considerations and build duration. Additionally, take care when considering neighbour proximity for side and wraparound extensions, as close boundaries might affect daylight access and privacy. It’s useful to carefully examine your property boundaries, existing landscaping or outbuildings, and easy access routes before narrowing down your options. Consulting with experienced professionals who understand these site-specific factors early will help clarify which extension types are viable given your unique property constraints and goals.
Know the permissions and technical checks before you commit. Small, single-storey additions can sometimes fall under permitted development if they meet size, height and siting rules; larger or taller works commonly require planning permission. Building Regulations approval is always required for structural safety, thermal performance, ventilation and fire safety; these standards are non-negotiable for completed, safe buildings. For significant works such as double-storey or extensive wraparound extensions, a structural engineer should assess load-bearing walls and foundations to identify any need for reinforced beams or deeper footings. Restricted access, nearby trees, existing drainage and utility runs are practical constraints that affect cost and method. Where a boundary is involved, consider Party Wall procedures early. Discuss planning and building regulation routes with your designer or local authority before construction starts so you understand likely conditions and avoid avoidable delays. We can carry out the construction trades listed on our website and will work with the designers and consultants you or your project team appoint.
Every property is unique in construction and site conditions, influencing extension feasibility. Older homes may require specialist foundations or materials. Soil quality, drainage, nearby trees and underground services affect foundation design and costs. Signs like wall cracks or uneven floors should prompt structural surveys before building. Construction access is another key factor; narrow or confined sites might need special logistics that impact timelines. Investing in a professional site survey and advice before commencing work helps avoid surprises, ensuring your extension is safe, compliant and durable.
