Frequently asked questions
Straight answers on design, planning permission and building regulations.
What areas do you cover?
We serve Hampshire and surrounding areas including Southampton, Winchester, the New Forest, Romsey, Eastleigh, and often work into Dorset and West Sussex.
Do I need an architect for my project?
For most extensions, loft conversions, and renovations, a qualified architectural technologist like our team provides everything you need, often at a lower cost than a chartered architect. We handle all design, planning, and building regulations.
How much does a consultation cost?
Your initial consultation is completely free. We'll discuss your ideas, assess your property, and provide guidance on feasibility, budget, and timescales before any commitment.
How long does the process take?
Timelines vary by project. A typical extension design takes 4 to 6 weeks, with planning permission usually taking 8 weeks. We'll give you a clear timeline at your consultation.
Do you handle planning permission?
Yes, we manage the entire planning application process on your behalf, including all drawings, documentation, and liaison with the local authority.
Can you manage the build as well?
Absolutely. We offer full design-and-build packages with project management. We source and coordinate trusted builders and tradespeople, keeping you informed every step of the way.
How much do house extension plans cost?
The cost of extension plans depends on the complexity and size of your project. A straightforward single-storey rear extension typically costs less than a complex two-storey or wrap-around design. We provide a clear, fixed fee quote at your free consultation so you know exactly what to budget. Our fees cover design, planning drawings, and building regulations drawings.
Do I need planning permission for a house extension?
Not always. Many single-storey extensions fall under Permitted Development rights, meaning you can build without a planning application. However, this depends on your property type, location, and the size of the extension. We assess your specific situation during the free consultation and advise on the best route.
What types of house extensions do you design?
We design all types of house extensions including single-storey rear extensions, double-storey extensions, side extensions, wrap-around extensions, orangeries, and garage conversions with extensions. Each set of plans is tailored to your property's style and your requirements.
How long does it take to get extension plans drawn up?
The design phase typically takes 3 to 4 weeks from the initial survey to completed planning drawings. If planning permission is required, the council determination period adds approximately 8 weeks. Building regulations drawings follow once planning is approved. We provide a detailed timeline at your free consultation.
Will the extension match my existing house?
Absolutely. We design every extension to complement your home's existing architecture. Whether that means matching brickwork and roof tiles exactly, or creating a striking contemporary contrast with large glazed openings, we ensure the extension looks like a natural part of your property.
Can you help with interior layout as well as the extension?
Yes. We consider the full interior flow when designing your extension, including how the new and existing rooms connect. We can redesign your ground floor layout so the extension integrates seamlessly with your kitchen, dining room, and living spaces.
Do you provide structural engineering calculations?
We coordinate with structural engineers to provide beam calculations, foundation details, and any steelwork specifications required for your extension. These are incorporated into your building regulations drawings so your builder has everything in one package.
What areas in Hampshire do you cover for extensions?
We design house extensions across Hampshire including Southampton, Winchester, Fareham, Eastleigh, Romsey, the New Forest, Chandlers Ford, Totton, Hedge End, Bishops Waltham, and surrounding areas. We also cover parts of Dorset, Wiltshire, and West Sussex close to the Hampshire border.
What types of loft conversion do you offer?
We design all types including Dormer conversions (creating additional headroom and floor space), Mansard conversions (ideal for terraced homes), and Hip-to-Gable conversions (perfect for detached or end-of-terrace properties). We'll recommend the best option for your home.
Do I need planning permission for a loft conversion?
Many loft conversions fall under Permitted Development rights and don't require planning permission. However, this depends on your property type, location, and the scale of works. We'll assess this at your free consultation and handle any applications needed.
How much does a loft conversion cost?
Costs depend on the type of conversion and specification. We provide transparent guidance at your consultation and can design to suit a range of budgets. A loft conversion is typically more cost-effective than a ground-floor extension per square metre.
How long does a loft conversion take?
The design and planning phase typically takes 2 to 3 months, with the build taking around 6 to 10 weeks depending on complexity. We'll give you a clear timeline for your specific project.
Is my loft suitable for conversion?
Most lofts can be converted, but key factors include head height (ideally 2.2m+ at the ridge), roof pitch, and available footprint. Our free survey will determine exactly what's possible with your property.
Will a loft conversion add value to my home?
Yes. A loft conversion is one of the highest-return home improvements. On average, a well-designed loft conversion adds 20 to 25% to a property's value, often far exceeding the cost of the work.
