One Team From Initial Design to Final Finish
A home extension involves much more than the building work itself. Design decisions, planning requirements, structural work and multiple trades all need to be coordinated in the correct order.
DB Sharp & Sons offers an integrated design and build service, bringing together building, architectural, plumbing, heating and electrical expertise under one experienced team.
Depending on the requirements of your project, we can support you with:
- Feasibility drawings and early budget guidance
- Planning drawings and submissions
- Building Regulations drawings
- Structural calculations and design
- Groundworks and structural construction
- Roofing, windows and external finishes
- Plumbing and heating installations
- Electrical installations
- Kitchens, bathrooms and internal finishes
- Decorating and final completion
The company’s architectural service already covers feasibility, planning submissions, Building Regulations drawings and structural calculations, while its wider building team coordinates electrical and plumbing work as part of larger projects.

Frequently Asked Questions
Q: Do I need planning permission for a home extension?
Not every extension requires a full planning application. Some projects may fall within permitted development rights, provided they meet specific limits and conditions. The requirements depend on factors including the extension’s size, position, property type and location. Most extensions will still need Building Regulations approval.
Our architectural team can review the project and help establish which permissions and approvals are likely to be required.
Q: Can you help with the design and planning application?
Yes. Our architectural services include feasibility drawings, planning drawings and submissions, Building Regulations drawings, structural calculations and liaison with relevant specialists.
Q: Do you build both single and double-storey extensions?
Yes. Our previous projects include single-storey and double-storey extensions, as well as extensions completed alongside substantial internal renovations.
Q: Can you manage the plumbing and electrical work?
Yes. DB Sharp & Sons brings together building, electrical, plumbing and heating expertise, allowing the different stages of the extension to be coordinated through one team.
Q: How long does a home extension take?
The timescale depends on the size and complexity of the extension, the design and approval process, access to the property and the level of internal finishing required. Once we have assessed the plans and visited the property, we can provide a more realistic programme for the work.
Q: Can we remain in the property during the extension?
This depends on the scale of the project and which parts of the property will be affected. For some extensions, it is possible to remain at home for most of the work. Larger renovations may require alternative arrangements during certain stages. We will discuss disruption and access with you before work begins.
Q: How much does a home extension cost?
Costs vary according to the size, design, structural requirements, materials and level of finish. We begin with a consultation and site assessment before providing a clear quotation based on the agreed scope.
Q: Which areas do you cover?
DB Sharp & Sons carries out home extension projects across Hertfordshire, including Letchworth, Hitchin, Stevenage, Welwyn, Baldock and surrounding towns and villages. The wider building team also works in parts of Bedfordshire and Cambridgeshire.
