Syze Developments Extension Builders

Our Approach To Building An Extension

A big project can be daunting – we aim to make it as transparent and predictable as any other service.

Consultation

Understanding your vision comes first. However far you’ve got with planning, we’ll work with you to arrive at a solution that meets your needs and satisfies all necessary regulations. Our long experience frequently helps to add clarity or suggest innovative features for your living space.

Budgeting

Once the design is established, we produce a detailed report showing the cost of materials, labour, permits and other associated expenses. This transparent cost breakdown makes it easy to understand the full scope of the project – allowing you to identify cost-saving opportunities.

Construction

An accurate schedule outlines the entire build – from foundations to finishing touches. Progress is closely monitored to ensure the plan is followed, with problems addressed immediately. Our quality standards ensure that your complete satisfaction is guaranteed from the outset.

Frequently Asked Questions

If you’re dreaming of building an extension onto your home, we recommend first engaging with an architect who will be able to help you explore your options and advise if planning permission will be needed. You will then need to appoint a structural engineer to design the floor and roof structures, as well as provide calculations for supporting beams. View our top tips for planning your extension here.

Whether you will need planning permission for your home extension will depend on the height, length, materials and site restrictions. We can help you to understand what planning permission you might need once we get an understanding of your requirements. You might find it useful to see our article on planning your extension.

Absolutely. A major change to your home can be a daunting prospect if you’re doing it for the first time. Ask us for a consultation and we’ll happily look over whatever plans or sketches you have. We can suggest cost-effective solutions or point out problems early.

When extending your home, you should expect a timeline of at least 16 to 18 weeks from start to finish. If your project is more complex, such as if you are building a second storey, this will take additional time. You can check out our article for more information on how long it takes for an extension to be built.

All homes are different and every extension is unique. But materials and labour costs are surprisingly stable – and we can predict a rough budget even with basic details. Use our budget estimator at the bottom of this page to get an idea.

The number one concern from customers is that the cost will increase once underway. That doesn’t happen with us. Our contract is approved by the Federation of Master Builders and we project manage carefully to keep the everything on time and to budget.
