Our House Extension Process From Consultation to Completion

Consultation & Site Assessment

We begin with a consultation to understand your requirements, ideas and the type of space you want to create. A site assessment then considers the existing property, available space, access and practical site conditions before the project moves forward.

Design, Planning & Construction

The project is developed through the relevant design, planning, structural and technical considerations. Once prepared, work progresses through site preparation and groundworks, foundations and structural construction, followed by roofing, windows, doors and external weatherproofing.

Services, Finishes & Handover

With the main structure complete, plumbing, electrical work and other building services are installed. We then complete plastering, flooring, decoration and agreed finishes before carrying out final checks, addressing outstanding requirements and handing over the completed extension.

How Much Does a House Extension Cost in Hampshire?

Planning your budget? Request a detailed quote based on your property, requirements and proposed extension.

Extension Size: Larger extensions generally involve more materials, labour and construction work.

Design Complexity: Bespoke layouts, structural changes and more complex designs can affect the overall cost.

Ground Conditions and Foundations: Ground conditions and foundation requirements can influence excavation and construction costs.

Structural Work: Steelwork, structural openings and alterations to the existing property can add to the project requirements.

Windows and Glazing: The size, specification and number of windows, doors and glazed areas can affect the budget.

Kitchen or Bathroom Installation: New kitchens and bathrooms involve additional plumbing, electrical work, fixtures and finishes.

Roofing: Roof design, materials and structural requirements contribute to the overall cost.

Internal Finishes: Flooring, plastering, decoration and other finishes vary depending on specification.

Professional and Approval Costs: Depending on the project, professional design, structural, planning and Building Control costs may also need to be considered.

Creating Energy-Efficient and Comfortable Extensions

Want your extension to feel comfortable throughout the year? Contact our team to discuss insulation, glazing and building services.

Insulation and Thermal Performance: Suitable insulation helps improve comfort and reduce unnecessary heat loss.

Windows, Glazing and Natural Light: Good-quality glazing can provide natural light while contributing to the thermal performance of the extension.

Heating, Ventilation and Building Services: Heating and ventilation should be considered alongside the overall design and intended use of the space.

House Extension Considerations for Hampshire Properties

Have a property in Hampshire? Speak to our team about the specific conditions and requirements that may affect your extension.

Older and Period Properties: Older homes may require careful consideration of existing materials, structure and construction methods.

Plot, Access and Available Space: The size and layout of the property can influence extension options, access and construction logistics.

Existing Structures, Drainage and Ground Conditions: Existing foundations, drainage and ground conditions should be considered before construction begins.

Neighbouring Properties and Site Constraints: Boundaries, access and neighbouring buildings can influence the design and construction process.

Local Planning and Property-Specific Requirements: Planning requirements can vary depending on the property and its location.

Conservation Areas and Character Properties: Additional design considerations may apply where properties are within conservation areas or have specific character features.

Is Extending the Right Option for Your Home?

Not sure whether an extension is the right solution? Speak to our team about your space requirements and available options.

Extending is not the same solution for every property. The available space, existing layout, planning requirements, budget and intended use should all be considered before deciding whether to extend. A well-planned extension should provide useful additional space while working with the existing property.

Frequently Asked Questions About House Extensions

Do I need planning permission for a house extension?

 It depends on the proposed extension, property and applicable planning rules. Some work may fall under permitted development while other projects require planning permission.

Permitted development rights allow certain types of home improvement and extension work without a full planning application, subject to specific conditions and limitations.

Most house extensions involve Building Regulations requirements covering areas such as structure, insulation, fire safety, ventilation and drainage.

Costs vary according to size, design, structural work, foundations, materials, services, finishes and professional requirements.

 The timeframe depends on the size, complexity, approvals, site conditions and construction requirements.

 Not every extension requires one. The need depends on the location and nature of the proposed work and its relationship with neighbouring properties.

This depends on the scale of the work, access, utilities, safety and which areas of the property are affected.

 Older properties can often be extended, but the existing structure, materials, foundations and character may require additional consideration.

Yes, extensions can be designed to include kitchens, bathrooms and other spaces where the layout and services allow.
