During the survey we map out practical options, explain the necessary regulatory checkpoints and describe the preparatory work so you can assess scope, cost and likely disruption.
EXPLORE THE OPTIONSOUR SERVICES / 06
There are several extension styles that homeowners in Stevenage can consider, each suited to different property layouts and requirements. Understanding the distinctions helps you choose the most appropriate approach for your space, budget, and long-term plans.
Single-storey extensions typically add space by expanding one level of your property, often at the rear. They are suitable for enlarging kitchens, dining areas or living rooms. These extensions require careful assessment of garden space, depth limits, and existing home structure to ensure smooth integration.
ENQUIRE ABOUT THIS SERVICEDouble-storey extensions provide additional floorspace both downstairs and upstairs, allowing for extra bedrooms or bathrooms. Due to increased height and structural demands, these require thorough consideration of foundations, neighbouring property impact, and compliance with building regulations.
ENQUIRE ABOUT THIS SERVICERear extensions focus on extending the back of your property to enhance kitchen or living spaces. Site access for construction and clearances from neighbouring boundaries are important factors. Rear extensions can be single or double-storey, depending on your needs and property suitability.
ENQUIRE ABOUT THIS SERVICESide extensions expand your property's footprint sideways, often useful where front or rear space is limited. They can create larger rooms or additional ones but may require boundary agreements and consideration of driveway or garden alterations.
ENQUIRE ABOUT THIS SERVICEWraparound extensions combine rear and side additions for maximum space gain. These demand detailed planning to manage the complexity of footprints, roof design, and harmonious blending with the existing building’s appearance and structure.
ENQUIRE ABOUT THIS SERVICEOUR PROCESS / FOUR STAGES
From initial enquiry through to completion, a house extension involves several distinct stages that ensure your project meets your needs and complies with relevant regulations. Understanding these steps helps you plan and engage constructively with your builder.
The process begins with an on-site survey to assess your property’s layout, access, and existing structure. This stage identifies constraints like boundaries, site access, and any required structural investigations, laying groundwork for accurate design and costing.
Next, the extension design is developed to align with your goals and property characteristics. Assessment of whether planning permission or permitted development rights apply is undertaken, along with early awareness of building regulations requirements.
Where necessary, formal approval from local authorities is sought for compliance with building regulations and planning rules. This step ensures structural safety, energy efficiency, and legal conformity prior to construction starting.
Following approvals, the build phase includes groundwork, foundations, structural framing, roofing integration, and external walls. Interior finishing such as plastering and joinery follows. Constant communication helps manage timelines and disruptions.

INSIGHT / House Extensions in Stevenage
When considering a home extension, informed decisions go beyond mere space gain. Differing types of extensions suit various property conditions, lifestyles and local regulations, all of which impact feasibility and ultimate satisfaction with your project.
Choosing the right extension involves evaluating your property’s footprint, garden size, and structural capacity. Single-storey rear extensions often suit maximizing garden views but may be limited by neighbour proximity or planning rules. Side extensions require sufficient lateral space and careful boundary considerations. Wraparound extensions can dramatically increase floorspace but add complexity and cost. Access for construction vehicles and material deliveries is another important factor. Early site assessment helps identify suitable options aligned with your lifestyle requirements and realistic construction potential. When deciding between single-storey and double-storey extensions, consider not only the space you need but also how the addition impacts your property’s structure and light. Single-storey extensions often provide easier build processes and less disruption, suitable for enlarging kitchens or living areas without affecting the bedrooms upstairs. Double-storey extensions accommodate growing family needs by adding extra bedrooms or bathrooms but require significant structural work such as underpinning foundations and integrating new staircases. Additionally, the height increase may affect neighbouring properties’ light and privacy, potentially requiring more rigorous planning scrutiny. Wraparound extensions, combining side and rear elements, maximize footprint but increase complexity; such projects require careful evaluation of existing wall conditions and roofline integration. Access constraints in Stevenage, such as narrow streets or limited garden space, might restrict heavy machinery entry and material storage onsite, influencing build methods and timescales. Early consultation with your contractor about site access, soil quality, and load-bearing walls helps identify feasible options and avoid costly redesigns after groundwork begins.
Not all extensions need formal planning permission—many fall within permitted development rights if they meet stringent size and positioning criteria relative to boundaries and existing building. However, local policies and listed status can restrict these rights. Building regulations approval is mandatory to verify the safety and energy performance of the new build. This includes foundation standards, fire safety, insulation, ventilation, and structural integrity. Collaborating with your contractor to clarify these steps upfront ensures your project’s legality and long-term compliance, avoiding costly retrospective actions. Beyond planning permissions, structural considerations are crucial when extending your home in Stevenage. Load-bearing walls in existing structures might need temporary supports or partial removal to open spaces between old and new areas. Where foundations are shallow, underpinning is often necessary to support additional loads, especially in double-storey or wraparound extensions. Local ground conditions, such as clay soil common in Hertfordshire, may impact foundation choices and costs. Party wall agreements should be considered if your proposed side extension is close to shared boundaries; these legal notices prevent disputes by formalising responsibilities for adjoining properties. Additionally, incorporating modern insulation and ventilation solutions within your extension not only satisfies building regulations but also enhances energy efficiency, an increasingly important consideration with rising fuel costs. Working with a contractor experienced in both construction and regulatory compliance ensures your extension is structurally sound and meets all current safety and environmental standards, avoiding the risks and potential delays tied to non-compliance.
Construction can be disruptive, so realistic planning around timelines, budget contingencies, and temporary living arrangements helps everyone involved manage expectations. Storage space for materials must be secured, and neighbours notified where appropriate. Weather conditions may affect build progress, especially for roofing and bricklaying. Clear, ongoing communication with your builder supports problem-solving and timely updates. Engaging accredited professionals safeguards quality and security, keeping your extension project on a practical path towards completion. The scope of your house extension will dictate construction duration and the type of living arrangements you might need during the build. Single-storey rear extensions typically cause moderate disruption but may allow you to remain in your home if rooms going under construction can be worked around. Material delivery and storage space are also critical factors; limited access at Stevenage sites might require just-in-time deliveries to avoid congestion and damage to landscaping. Be prepared for potential unforeseen issues uncovered during construction, such as discovering hidden drains or uneven ground, which can impact costs and timelines. Maintaining clear communication with your contractor about daily progress and challenges mitigates stress. Discuss insurance cover for accidental damage and ensure health and safety protocols are followed to protect your family and neighbours throughout the project.

QUESTIONS / HOUSE EXTENSIONS
Here we address typical enquiries about permissions, timelines, and working with Raptor Roofing to help you prepare your own project discussion.
ASK ANOTHER QUESTIONNot always. Many house extensions fall under permitted development rights if they meet specific size, height and boundary rules. However, these vary by property type and location, so it’s important to check with Stevenage Borough Council or consult a professional before starting work.
The build duration depends on extension size and complexity. Factors like site access and weather also influence timescales. We confirm the schedule in writing after the survey.
We provide the core building trades commonly needed for extensions: roofing, brickwork and carpentry. For any enquiry we confirm the project scope from drawings or a site visit, outline which tasks we can carry out in-house, and identify where a specialist subcontractor is required. Send us the brief or plans and we’ll explain what’s covered, what needs arranging separately, and the practical next steps.
Share your extension goals, existing property details, and any design ideas. Discuss planning and building regulation considerations, clarify included services, and ask about timelines, costs, and any potential limitations you should be aware of.
For older properties or those with known foundations or subsidence issues, a structural survey by a qualified engineer can identify challenges early. This helps avoid delays or unexpected costs during construction and ensures the extension’s safety.
Extensions close to neighbour boundaries may impact privacy, light or access. It’s good practice to discuss your plans with neighbours and consider boundary regulations to minimise disputes or objections during planning and building stages.
